Wahoo Further Clarifies Canyon/Trek/Giant KICKR Incompatibilities with New Adapter

If there’s anything the internet is good at, it’s sleuthing through imagery to find inconsistent details. Last month when Wahoo and Canyon casually dropped a support update out saying that the Canyon Ultimate CF frames (specifically the rim brake variants) weren’t compatible with Wahoo KICKR17 , KICKR18 , KICKR CORE , or KICKR V5/2020 . This also applied to a number of Giant and Trek trainers. They said it would rub the frame, and then the frame would catch fire and give your riding buddies Syphilis. Or something like that.

For realz though, they said it’d rub your frame and break it– and indeed, some Canyon Ultimate users had started noticing this back this past summer . However, that didn’t seem to be the case for me and my Canyon Ultimate CF SL . It was absolutely nowhere near touching anything. Even in my most laborious sprint, nothing flexed enough to do anything. Albeit, I do suck at sprinting.

So this is the long story of vindication for my bike. And also Wahoo’s new adapters.

(Or, you can just skip over the juicy internet mob parts, and go straight to the update parts at the end…but that’s not what you want to do on this mid-January Wednesday. You probably need some excitement in your life about now.)

My Canyon Ultimate:

As always, the internet does not suck at sleuthing. And it didn’t take long after Wahoo & Canyon’s announcement before the comments started flooding in on my older posts and YouTube videos, telling me I was going to soon die of a shattered bike.

Now mind you, I’d been riding an assortment of Wahoo KICKR trainers for the better part of 3.5 years at this point. I’d had the KICKR 17 in the summer of 2017, then the KICKR18 and KICKR CORE from the summer of 2018, and then the KICKR2020 from mid-summer of 2020. At no point has my bike touched or been touched in an inappropriate way, and my bike still hasn’t started smoldering or shattered. I mean, sure, my drivetrain is always a dumpster fire that needs cleaning – but the frame itself hadn’t combusted yet.

So, I went back to Wahoo with an exceptionally lengthy e-mail asking for clarification. I’m pretty sure by now anytime a company receives a long e-mail from me, they know it’s unlikely to be good news.

(The e-mail included half a dozen links to both Wahoo and Canyon pages showing numerous inconsistencies in the wording and naming, including a reference on a single page that pointed to a mostly internal reference model number for the Canyon Ultimate CF SL)

A boatload of e-mails back and forth and I finally had my answer.

Turns out, only the 2019-2021 variants of the Canyon CF SL rim-brake versions are actually impacted. Prior variants, like my lovely 2016/2017 variant aren’t impacted at all. And in fact, unofficially the 2019-2021 variants can be ‘solved’ by simply turning the adapter around and using the 135mm side, which eliminates any unwanted rubbing. After all, this is not a Tinder date – rubbing was not appreciated.

Important note though that as of today – January 20th, 2021, Canyon hasn’t however finished the approval of this axle adapter flip-around, nor, the upcoming new axle adapter.

So while both Canyon and Wahoo’s site just blanket list Canyon Ultimate with rim brakes being incompatible, in actuality it’s only certain newer model years. I don’t know if Wahoo or Canyon will update their 28 different pages that list these models all over their sites, but, at least I got some clarity that mine is perfectly fine – and maybe yours too.

New Wahoo Axle Adapters:

As it stands today, the following bikes are considered incompatible with the Wahoo KICKR 17/18/20 and KICKR CORE trainers:

• 2021 Trek Emonda
• 2020-2021 Trek Domane & Madone
• 2021 Giant TCR Advanced Pro
• 2020 Cervelo S5
• 2019-2021 Canyon Ultimate CF SL/SLX/CFR rim brake models* *Fix pending final approval from Canyon

Each of these however can be fixed via a new adapter that Wahoo has started production on, and will be made available shortly (for free). These new parts essentially add slightly extra clearance for the frame to avoid undesirable contact with the KICKR trainer.

The three parts at left will replace the two existing parts at right (above) and give greater frame compatibility and clearance. They are as follows:

1.    New 12×142 Non-Drive Adapter 2.    New 12×142 Drive Side Insert 3.    New 12×142 Drive Side Cap (allows the frame to pivot) 4.    Original Drive Side 142/148 Adapter provided with the KICKR/CORE 5.    Original Non-Drive Side 142/148 adapter provided with the KICKR/CORE

More specifically, the following:

– Part 1 replaces the old/stock non-drive side KICKR 142/148 adapter (#5) – Part 2 and 3 replace the old/stock drive side KICKR 142/148 adapter (#4)

Finally, there will also be a new 148-only adapter that will replace the existing combined 142/148 adapter, but I don’t have a photo of that yet.

These new adapters will be made available to any customer upon request, via customer support, for free. That’ll happen in the next few weeks. Additionally, a rolling production change will occur for new KICKR’s coming off the assembly line to include these new adapters instead of the older ones.

Ultimately, it’s virtually impossible for bike trainer companies to test every single bike and bike configuration on the market. It’s just never gonna happen, and also physically impossible to have every bike ever made on hand to test/validate. Still, I think there are ways that bike trainer companies can work with the major manufacturers to ensure these sorts of incompatibilities are quickly discovered and listed before they get too far down the road.

Which isn’t to say that Wahoo or Tacx or Elite needs to send out pre-production unannounced trainers to all the major bike companies to validate, because honestly, that’ll just result in leaks. However, having new trainer units ready to roll to the major frame makers as soon as a product is announced would be helpful so that incompatibilities can be found quickly and documented. And on the bike manufacturer’s part, there probably has to be a realization that the vast majority of customers of high-end bikes are using them on trainers. After all, when these 2020 bikes came out, the KICKR 17/18/CORE were already on the market for quite some time.

But the best news here is that I’ve now got a post I can point to the next time someone watches one of my Wahoo trainer videos telling me my Canyon is gonna shatter. An answer for them, and a page view for me. See…win-win!

With thanks for reading!

Wahoo KICKR V6/2022 (Current Version)

Here's a few other variants or sibling products that are worth considering:

Wahoo KICKR Direct Connect Adapter

And finally, here’s a handy list of trainer accessories that most folks getting a smart trainer for the first time might not have already:

Apple TV 4K 64GB WiFi (2022)

There's no better bang for your buck in getting Zwift (or FulGaz/etc) on your big screen TV than Apple TV - it's the primary way I Zwift.

Basic Trainer Mat

This is a super basic trainer mat, which is exactly what you'll see me use. All it does is stop sweat for getting places it shouldn't (it also helps with vibrations too).

Elago R1 Apple TV Remote Silicone Case with Strap

I use Apple TV for Zwift the vast majority of the time, but also just for watching YouTube/Netflix/etc on the trainer. The Apple TV remote sucks though. This $8 case fixes that, it's a silicone strap that makes it easy to grab, but also has a strap to easily place on the edge of your handlebars. Boom! Note: Not compatible with 2021 Apple TV Edition.

Front Wheel Riser Block

Here's the thing, some people like front wheel blocks, some don't. I'm one of the ones that do. I like my front wheel to stay put and not aimlessly wiggle around. For $8, this solves that problem. Note some trainers do come with them. Also note, I use a riser block with *every* trainer.

Honeywell HT-900 Fan

I've got three of these $12 fans floating around the DCR Cave, and I frequently use them on rides. They work just fine. Sure, they're not as powerful as a Wahoo Headwind, but I could literally buy 20 of them for the same price.

Indoor Cycle Trainer Desk (RAD/CXWXC/Vinsetto/Conquer/etc...)

This desk is both a knock-off of the original KICKR Desk, but yet also better than it. First, it's got wheel locks (so the darn thing stays put), and second, it has two water bottle holders (also useful for putting other things like remotes). I've been using it as my main trainer desk for a long time now and love it. Cheaper is better apparently. Note: Branding varies by country, exact same desk.

KOM Cycling Trainer Desk

This is by far the best value in trainer desks, at only $59, but with most of the features of the higher end features. It's got multi-tier tablet slots, water bottle holders, non-stick surface, adjustable height and more. I'm loving it!

Lasko High Velocity Pro-Performance Fan (U15617)

One of the most popular trainer fans out there, rivaling the Wahoo Headwind fan in strength but at a fraction of the price. It doesn't have smartphone/ANT+/Bluetooth integration, but it does have secondary outlets. I've been using it, and a similiar European version lately with great success (exact EU variant I use is automatically linked at left).

Tacx Tablet Bike Mount

I've had this for years, and use it in places where I don't have a big screen or desk, but just an iPad or tablet on my road bike bars.

Thanks for sharing. I went back and forth with Wahoo about my 2020 Trek Checkpoint SL5 in Nov/Dec to eventually be told, after many photos, that my Kickr ‘17 was not compatible. Had to buy an adapter for a Snap that was my wife’s ($59.00) to make that work with the Checkpoint. Needless to say, I was not happy. I really hope this is the solution. The Snap is OK, but nowhere near as nice as the kickr.

The Checkpoint issue. Also must remove the handle on the kickr to allow for the dropout adjuster.

Wahoo “sucks” big time lately since they can’t make reliable heart rate monitors…. The HR Tickrs 2 and X2 are useless!! Firmware is bad. Such a sad story!!

I’ve tried the Tickr line before and always have connectivity issues. I have no idea why they’re so beloved in the fitness community other than “great marketing” (and first to market with BLE + ANT+).

Conversely, the Polar H10 has been rock solid for me and my spouse for years.

Hi Ray. Thank you very much for this information. I happen to have a 2019 rim brakes Ultimate CF and just noticed the rbbing on my frame. I bought my Kick Core last may and this incompatibility did not exist at this time. What should I do ? Shall I stop using my trainer straight away ? Is my frame damaged and unusable ? Does it need some repair ? Should I contact Wahoo support ? Let me know…

As a starting point, you should check the frame to see if there’s any damage. Check out that Reddit link at the top to see what damage would look like.

Assuming none, then flip around that adapter and use the 135mm side for now to keep things safe.

Thanks. As you can see there’s been some rubbing against my frame… :-/ I flipped the adapter and there is no contact now. I’ve contacted Canyon support to be advised… Now I’m wondering if I can use my bike without risk.

I just had an answer from Canyon, I was advised I can continue to use my bike but indicated not to use any Wahoo trainer.

I also have Ultimate cf. Do you need to use force to spread the part where the wheel is?

Thanks Moshik

Been using my Trek Emonda 2021 and my Trek Madone 2020 consistently on my Kickr Core 2020 and I never noticed any possible rubbing whatsoever. Or maybe it’s just me not caring at all XD, certainly doesn’t seem a major endangering issue .

Update: I just noticed i have similar scratched on my Emonda. I have sent a support request asking whether this can affect my bike ride safety.

Hi Luca Did you get any reply from Wahoo and would they deliver a adapter to fix the problem? I have just purchased Kickr Core and I am now realizing there is a compatibility problem with my Emonda 2021.

Here’s their latest reply, dated 28th Jan though ?

“Your replacement Adapter has been ordered and you will receive an update with the tracking details once it has shipped.”

Good to have that overview and covered by Wahoo. Not natively speaking English, but there feels something not right with this sentence?

It’s just never gonna happen and physically impossible to have every bike every made

Yeah, it’s not the prettiest of sentences, and ‘every made’ should at a minimum be ‘ever made’. Will do some tweaking…

This also applied to a number of Giant and Trek trainers. Assume bikes

Thanks for that Ray, very interesting, roughly how much clearence should there be between the frame and the trainer? I am currently using my Ridley Fenix sl disc, with thru axle, on a 2020 trainer, but I’ve noticed just lately when I’ve been swapping it for my wifes Scott with QR, that when I’m swapping the adapters the cassette side adapter has started to become very difficult to get out, that difficult that I need a screwdriver to prise it out, but I also noticed when I’m tightening up the thru axle you can see the frame and rear mech pull in quite a lot? Hope that makes sense.

As opposed to my Scott plasma that sits up in the air at an angle of ~22 degrees cause the chain stays foul on The neo, driving and just about all other trainers.

That was what forced me to get a H3 when my Direto broke. I have a Plasma 3 Premium that is known to be incompatible with the Neo, and when I borrowed a KICKR it fouled my Canyon Ultimate as per this article. The H3 is perfect with both (and the cheapest of the three top level trainers – win win!)

Yeah mine was the team issue and I have found a low tech solution by putting the red of the trainer up on blocks. Tilt the whole thing forward and it clears.

And the Saris H3 comes with a bunch of adapters included in the box… don’t need to purchase additional adapters later…

Oooof. Had no idea of this and have been riding my Domane on the Kickr Core for months. Do you know if we can go ahead and request the replacement parts? Off to look for damage now…

Any idea what the issue is with the TCR? Wahoo seems to only list the Advanced Pro 0, but you list all TCR Advanced Pro. I can’t imagine what would make the 0 different from the 1, so I am guessing your list is right?

All bikes and trainers are designed using Computer Aided Design software.

They only need to share the interface surfaces.

Car manufacturers and suppliers have been doing this for decades.

To make life simpler going forward they need to agree standards.

Any idea about compatibility with gen 1 & 2 Kickr with new frames? Specifically the 21′ Emonda?

I have a 2020 Emonda Disc and had a Gen 2 Kickr.

While you could buy the adapter kit and give it a go, I would advise you not to try it.

First issue: there is hardly any clearance between the Kickr and the chain stay (around the place where the brake caliper sits). From what I’ve read the difference between the Gen 2 and the Gen 3 is a cutout around the axle to provide more frame clearance. I tried solving it by cutting out part of the trainer (the trainer is 5 years old and it was just empty space covered by a cap so I thought I’d just give it a shot).

I then installed the bike on the trainer, clearance was ok and I took the bike off again to check for any damage (better be safe than sorry).

That’s when I ran into a second issue.

I found that the part that screws on the quick release at the drive side and tightens things up I don’t know the name in English) had become stuck in the frame. I was afraid I had damaged the thread of the dropout but in the end I managed to (forcefully) pull it out without damaging the frame. Workaround n° 2: I filed off the paint, which did the trick.

I then tried riding the Kickr for 1 minute without resistance to check everything was ok. While everything seemed to be good that time round, when I took the frame off the trainer, I noticed that the paint on the 142mm adapter (that needs to inserted into the Kickr where the 135/130 mm adapter is usually placed) had been chipped off.

That’s when I decided I’d had enough. I was afraid the adapter would damage the frame in the long run so I decided to sell the trainer, tell potential buyers to stay clear of disc brake-equipped bikes and buy a trainer with actual thru-axle support.

I’d happily add some pictures but I have the impression that I can only add one so here’s the picture of the chipped 142 mm adapter.

You could try flipping the adapter as Ray suggests but (if my logic is sound) that will mean the clearance issue will be back.

Plus the dynamic clearance envelopes

This makes me feel much happier thanks Ray. I ordered my KICKR back in November, literally seconds after I pulled the trigger I spotted the compatability issue with my canyon (the same medal as Ray’s). I tried to cancel my order straight away but couldn’t so was staring down the barrel of the hassle of posting it back to wahoo. Anyway by the time it had turned up I had been digging around and spotted Ray using his ultimate on a KICKR. My new trainer arrived and I thought let’s put the bike on and see if anything is an issue. Couldn’t see one so for the past three months I’ve been riding in zwift with this constant worry at the back of my mind that my bike would disintegrate at any moment. Ray (and I guess to some extend wahoo), thanks you’ve certainly put my mind at ease.

I went back and forth with Trek & Wahoo multiple times, getting different answers each time. Until Wahoo finally gave me a bit more detail. They also changed their website several times regarding the emonda & domane issues. Turns out, the AL versions should be fine, but the carbon models are the ones having the issue. Here’s a table they provided me with the trek specific models that are having issues. My 2021 AL5 Domane seems to fit ok on the kickr, but i’m still going to apply for the new adapter. I wish they would update their website to list the SPECIFIC models of the frames that are impacted.

Thanks for posting that graphic, @ars!

I agree it would be very helpful if their Kickr bike compatibility info (not even a wahoofitness.com link, instead it links to some strange third-party website: yonyx.com) was more specific w/r/t to the specific models and what the issues are with each.

Why are trainers not able to fit within the bounds of a rear wheel? Isn’t the shape around the axel well defined. I’ve never heard of a wheelset not fitting. I’d accept that these aren’t designed to fit a 5spd freewheel but anything wider than 130mm should work.

While I’m here, I’d like to see cassette spacing adjustment on a trainer and not have to adjust bike from wheel to trainer to wheel.

Interesting to see this article. I’d not spotted the kid year releases on this subject. I actually engaged with you on twitter about it back in the summer! link to twitter.com

Both Canyon and Wahoo were a bit “huh?” when I contacted them about it, but the wahoo guys did say using the 135mm on the borrowed KICKR I was using was a possible solution.

In the end, when getting my permanent replacement once some stock re-emerged, I just got a H3 which is great with both the Canyon and my Plasma 3 TT bike (which has known incompatibility with the Neo).

Whilst I do get your point about trainer companies not being able to test against all know frames, the issues with the KICKR and Neo are largely of their own making. They could easily have a narrower dropout contact point in the case of the KICKR. The H3 is super narrow at that point and there’s a good 2+ cm of clearance. And I can’t imagine the Neo has to be quite than “long” at the front.

Technically it is trivial for the trainer companies to test every bike. The bike companies share the CAD surfaces – virtual testing. This is a failure of process to date.

It doesn’t rub on my Domane SL6 Disc either although others claim there is running. I wonder if the disc vs rim brakes scenario is the same situation here?

I had just acquired the Kickr V5 (2020) in October to go with the insideRide for my 2020 Domane SL6 when I read about rubbing. I was going to go the route of using a lathe to remove some of the material on the spacer / adapter as some have done but when I test fit the adapter with my frame I have several mm of space so it doesn’t actually rub.

Looks like Wahoo copied my solution to make the frame pivot in combo with the Climb :)

I’ve contact them a long time ago because the dropout om my Venge was getting damaged by the adapter. The adapter turned at the frame side instead of the Kickr side. My solution was an nylon washer on between the adapter and Kickr. Really curious to see how their solution performs because it looks like the are both metal.

Now that i look again i see that the washer is for the drive side. Now I am even more curious if the new adapter for the non drive side will also solve the problem. Am afraid not …

Wow, I’m surprised this issue is not more talked about. I just lifted the bike a few time and it was enough to create a bunch of carbon dust where the adapter meet the frame. I have used a similar solution, I made a plastic washer and installed it on the adapter (the section that goes in the Kickr) which allow it to rotate. I have ordered a nylon washer as a more permanent fix. I have contacted Wahoo before about that issue but they seemed not aware of the issue. On my aluminium bike it rubbed a bit of paint away which is not a big deal. Now on a carbon bike, the damage could be much more substantial.

You should just lightly tightened up the thru-axle, the bike should easily fall back down if lifted up at a 45 degree angle.

It may be that your thru axle is too tight?

It’s torqued with a torque wrench to 10Nm as required by the frame manufacturer.

Doesn’t #1 replace #5, and #2 replaces #4?

Yep, saw that as well…

I would agree with you there. I’ll confirm with Wahoo on that now that I take another look at the parts (they had sent over those specific mappings).

Just confirmed with Wahoo and swapped it around. Good catch!

To those wondering if it was causing damage or not, I really had to push to get my 21 Domane to seat. Took it off after one ride because I thought something was off and there was clear paint damage. So if you were able to seat your bike I’m hopeful that you don’t have any issues!

Same here. I have a 2021 Domane SLR7 and had a hell of a time mounting it..I decided my Emonda ALR would be my trainer bike.

I’m not sure I agree with the correction to the Canyon year variants. My 2016 Ultimate CF SLX is definitely impacted by this issue with the KICKR’18. I have managed to bodge a fix using some shims but its great to know there will be some revised adapters available as a permanent solution. Thanks for the update!

This thread from 2017 describes the same: link to weightweenies.starbike.com

For the Trek Emonda, does it apply to all models? I was considering a emonda ALR rim brake.

My Emonda ALR rim brake does not have any issues on the trainer.

Another incompatibility, although not the same as this one.

Specialized SL7 with Kickr 15/16 and Thru Axle adapter.

The non-driveside adapter piece that goes through the thru-axle hole on the frame is longer than the frame is wide, so when you tighten up the QR skewer to compress everything together, it doesn’t actually push on the outside of the non-driveside frame. It pushes on the end of the adapter which is poking too far through the hole in the frame, and therefore it doesn’t actually hold the bike tight.

I did raise this with Wahoo and they said they were unaware, but as it was an old trainer model it wouldn’t be resolved.

Kickr 16 replaced with one with native thru axle support and all is good!

I noticed they recently added the ’20 and ’21 Madone to the list despite previously only saying the Domane and Emonda have issues. I have a ’19 Madone SLR which as far as I’m aware was not changed for the ’20 model year. Should I be worried?

Update: I took a look at my driveside on the trainer. Seems to fit fine to the hanger, although there are some small marks on the frame that seem just like a layer of paint. Any suggestions?

A better pic

I have the same paint missing on my 2021 Madone SLR Disc. Don’t mind all the wax flakes in the pic.

the driveside spacer has a slight pattern on it. You can see it inprinted on the inside of the derailleur hanger in both my photos and @Toms. But while you can also see the pattern slightly on the photo Tom posted, you can’t on mine. Maybe there is a slight difference betweeen the ’19 and the 20-21 Madone?

seems like normal paint scratching from bumping on the trainer/wheel when mounting and taking off. I think the frames having the real issue are seeing the dropouts being chewed into, more than just superficial paint scratches

“Superficial paint scratches”???? First of all,, paint wear is mentioned in the notice that trek sent out. Secondly, do you know what paint wear leads to? Next step is carbon wear…aka frame damage. No amount of paint wear is acceptable, no matter how minor some may want to deem it. My nondrive dropout doesn’t have a single mark, scratch, or ding. It is absolutely perfect. My drive side has no paint left around the entire lip of the dropout. If it was being caused by just putting the wheel on or putting the bike on the trainer, then it would be on both sides.

Didn’t realize this was an issue until I read it here so I greatly appreciate the article. I took off my bike from my trainer which I’ve had it on since Dec and unfortunately I have this issue. Not sure if it’s just cosmetic (not a big deal cause the bike already has war scars) or something more structural. Bike is an Emonda SL 7

I’m curious if there have been similar issues identified with any of the other major competitors in the mid-high end direct drive trainer space? Have you heard anything about Tacx or Saris H3 issues related to incompatibilities with some of these bikes (Canyon/Trek)?

Is the added 5mm a legitimate stress to the frame? I have a 2021 Ultimate (rim brakes) and I bought a Kickr Core a couple of weeks before Canyon acknowledged the incompatibility issue. I bought in US, but live in the Middle East. Returning is not an option. Ugh!

Anyone knows the compatibility of the Canyon Ultimate CF SL rim brake to a Tacx Neo 2T?

Looking into buying that one. Tacx has not updated their compatibility document in a long time and Canyon cannot give a straight answer

Owner of a 2019 Canyon Ultimate SLX (rim brake) and a newly purchased Wahoo Kickr V5. Reached out to Wahoo customer service, and as of today’s email, the new adapter will still not fix the Ultimate’s incompatibility with the trainer.

I believe though they’re saying that officially it’s not compatible until Canyon gives it the blessing, which is what’s outstanding at the moment.

So I think I have a handle on this. I have a 2021 Ultimate (rim) and bought a Kickr Core in December. I ran into the same problem and caught it early enough that it only scratched the paint. Here is an update:

It’s fixable. Wahoo knows about the problem and is crafting an adapter for the 6 bikes determined to be incompatible. They won’t confirm dates, but have promised to ship the adapter free of charge when complete.

In the meantime, I had washers made. 26mm x 19mm of varying thickness. After playing with it, I determined that 1.5mm does the job. You can probably get away with 1mm, but 1.5 adds a little wiggle room. The 1.5mm washer is still within the width of the frame (there is no stretch/stress to the frame)

Canyon hasn’t approved anything and basically told me the problem can be solved by not putting my bike on the trainer.

I’ll use the Wahoo adapter, especially if approved by Canyon. That said, it’ can’t be any more effective than the 1.5mm washer.

Hi Timothy,

Thanks for your help. I actually got a good selling deal and sold the Wahoo. I’m going for the Tacx Neo T2 which Garmin/Tacx rep confirmed it was compatible for the bike.

Thanks for this useful info. Do you know if it just the 2021 Giant TCR Advanced Pro or does it affect the Giant TCR Advanced 2 Disc as I have just picked up my son’s new bike and he is desperate to try it out on a Kickr Core (we have snow forecast for the next few days).

Great site buy the way.

Thanks, mark

I can confirm that it does indeed affect the TCR Advanced disc models too as I have just checked. I have contact Wahoo who say the adaptors will be sent to retailers to distribute but speaking to my local retailer he knew nothing about the issue. They have contacted the local rep who said it only affects Trek bikes but Wahoo own website list the following: Canyon Ultimate with rim brakes [disc brake version still compatible] 2021 Trek Emonda 2020-2021 Trek Domane & Madone 2021 Giant TCR Disc Models 2020 Cervelo S5 Lauf True Grit

Looks like either need the adaptor or I will be selling one of the Cores to buy something else.

The 2020-21 Domane is fine but no room for error, anyone who has superficial damage isn’t being careful enough when installing. If is slightly misaligned you will get those teeth bite marks, you have to be really careful when installing it, I would request the new inserts once available.

Respectfully Sigs, I’ve got to disagree! I was incredibly careful and still managed to get paint chips after a single ride. More importantly, both Wahoo and Trek agree that you should NOT be riding the 20/21 Domane on the Kickr, and CAN request a replacement.

I’m super happy you’ve had good luck, though!

What do you mean by “request a replacement”?

I had been riding my ’20 Domane SL5 on this thing for 6 months before I learned about the issues. It’s a little tricker to seat, but seems stable once I tighten up the thru axle. Pic attached of what it looked like when I found out.

Hi Ray. Any word from Wahoo when they think these will be available? I’ve reached directly a couple of times but have not heard back from them. Thanks.

My LBS put me in touch with the local Wahoo rep who after checking told me they are expecting them to be released in a couple of weeks so as an end customer I’m hopeful that we will have them within a month. I’m in the UK

Tried my 21 Emonda SLR and it was a no go. I also tried my 21 Trek Supercaliber and drive side was not fitting as well.

I asked wahoo for an update on the issue as I am planning to buy a giant TCR disc. It seems that there are still some troubles with the new adapters since I got this response:

“Wahoo is doing all that it can to modify the current thru axle adapter design to accommodate certain frames in the marketplace and we are working closely with these manufacturers to ensure the success of these revisions. However, this process takes time. The bicycle manufacturers provided their feedback on the first run of these adapters and it was determined that additional revisions to the design were required. The investigation is still ongoing to determine if their recommended revisions can be made.”

As I recently bought the wahoo kickr v5 I will hold out on buying a giant TCR as I would like my new bike to also fit my smart trainer.

Keep up the good work!

I also received the same message… Anxiously awaiting a new part for a bike I already have.

Welp, after that recent email from Wahoo, I just sold my Wahoo KICKR Core and my Saris H3 will be here in a few days. I would have just waited it out, however my 2021 Trek Madone SLR 9 ETAP will be here this week too…..I certainly wasn’t willing to put my brand new SUPER EXPENSIVE bike on my Wahoo…I was already using a 2021 Trek Madone SLR on my Wahoo and it wasn’t having terrible issues, but it did chip the paint slightly on the dropout. I mostly didn’t like the part of the email where Wahoo said something like “it’s not possible to make a product compatible with EVERY bike out there”. Makes it sound like they’re accepting defeat on this one….

I’m in the same situation – my Canyon Ultimate with rim brakes already damaged. Interested in updates about subject – when those new adaptors will be available.

Thanks for posting this as I did not know about this until I saw it by chance. For those still watching this – latest update from Wahoo as at Mar 5th 2021 and quoting their email reply to me in full:

This email is a follow up to your support request with Wahoo. Wahoo is doing all that it can to modify the current thru axle adapter design to accommodate certain frames in the marketplace and we are working closely with these manufacturers to ensure the success of these revisions. However, this process takes time. The bicycle manufacturers provided their feedback on the first run of these adapters and it was determined that additional revisions to the design were required. The investigation is still ongoing to determine if their recommended revisions can be made. Wahoo is committed to doing all that we can to make our products compatible with as many frame designs as possible, but there are inherent limitations to making one product to work with all the various frame designs in our industry. Unfortunately we are unable to provide a specific timeline or estimated date for the availability of these adapters at this time. We appreciate your patience during this process and we sincerely apologize for the delay, we will provide additional information as it is available. Please let us know if you have any questions.

Looks like the first version was not ok and they are redesigning it (and it may never be solved for all bikes is being suggested).

Piling on here. Like many of you, I did not know this when I ordered my Domane AL 5. Found this out by going back to the Wahoo site to refresh myself on setting the Domane up on my Kickr V5. Based on Ray’s article, I too sent Wahoo an email asking for the adapters. I got the same reply. Here it is for the record:

Late in 2020 several bicycle manufacturers updated the frames on a few bike models that resulted with them being incompatible with our 2017 through current KICKR and all versions of KICKR CORE. Wahoo is working closely with the affected bicycle manufacturers to explore compatibility solutions for these frames. Wahoo is committed to doing all that we can to make our products compatible with as many frame designs as possible, but there are inherent limitations to making one product to work with all the various frame designs in our industry. We appreciate your patience during this process.

In the interim this support request will be placed ‘On Hold’ which will allow us to provide you with updates as they are available.

i think I will wait to see how things go before putting it on the trainer. Not good since I ride a lot of my trainer.

FYI my recent response from wahoo: When they mention “the article you reference” they are talking about this article.

“Your support request is on hold pending additional information becoming available of a compatibility solution for Trek frames on current production KICKRs. The article you reference contains incorrect information – this is something we are exploring however we do not have a solution available to ship at this time. We will provide you updates when they are available however we cannot offer a timeline for availability. Please do not use the bike on the KICKR in the interim – it is not compatible and will likely damage the frame.

I’ve been less than impressed with wahoos poor response time to questions and non helpful answers for such an expensive product.

Yeah, I’m not sure what/why Wahoo would say anything is inaccurate here. We literally went back and forth half a dozen times with the individuals overseen this, both before and after it was published to ensure it was crazy spot-on accurate.

Is this a problem only with the wahoo trainers?

I have a Direto XR and am considering buying a Giant TCR 2021.

I think you are fine. This issue is Wahoo specific.

I have the 2017 Kickr and an Emonda 2021 SLR after contacting Wahoo here was their answer Lee (Wahoo Fitness Support)

Mar 25, 2021, 2:13 PM EDT

We are actively exploring solutions for these frames but do not have a solution available at this time. Information online to the contrary is unfortunately not correct. We will contact you with any additional information on this as it becomes available. We sincerely apologize for any confusion.

So I’m at a loss for a solution.

“Information online to the contrary is unfortunately not correct.”

I’m not terribly sure why Wahoo supports keeps trying to passively-aggressively pass the buck here. At the end of the day, what they stated above was accurate – and verified by them – prior to and after publishing of this post, which noted that production would begin soon. In fact, they can even see that in the comments section above, when two part orderings they had sent me were typo’d (by them), and then a reader noticed, and I confirmed with them, and then fixed (all shown in the comments above).

The correct wording they should be using in their responses is:

“At this point, our adapters have been delayed further while we work with bike manufacturers to ensure it meets their specification.”

Unfortunately, Wahoo’s customer service on this issues has been absolutely horrendous, from my experience with this. Initially, Wahoo seemed to be responsive and helpful, but it quickly turned to blaming me and other excuses. A summary of my experience is below (sorry, its a bit ‘TLDR’).

On 27 January 2021 Wahoo asserted that my frame (2021 Domane) was on the incompatibility list at the time of my Core purchase (3 October 2020). Unfortunately for Wahoo, internet archives are easily searchable and I demonstrated their assertion be false. In my email to Wahoo, I provided a screen capture of the compatibility list from a 9 November 2020 archive of Wahoo’s website that clearly establishes that 2021 Domane was not on the incompatibility list published on Wahoo’s website, even a full month after my purchase of a Core. ( link to web.archive.org )

On 2 February, Wahoo asserted that the published incompatibility list is “Known Incompatible Bikes” and stated that it is the responsibility of the end user to ensure compatibility of Wahoo’s product with bike frames. However, I have reviewed all of Wahoo’s documentation provided with the Kickr Core and nowhere in the product manual does it provide any statement that the “the KICKR end user is ultimately responsible for ensuring that their bike frame is compatible with the KICKR trainers such that damage to the bike frame does not result from using the KICKR trainer”, nor does it provide any instructions to the end used on how one would assess compatibility with the bike frame.

On 2 February, Wahoo asserted that “To fully ensure compatibility, we recommend visiting a local Wahoo retailer to test your bicycle’s fit before purchasing.” However, I did visit a local Wahoo retailer on the date of purchase of my Kickr Core on 3 October 2020–my local Trek Store (to which I have receipts as proof)– and I was informed at that time (3 October 2020) that my 2021 Trek Domane was compatible with the Kickr Core that they were selling in store. Further on this point, I contacted my local Trek store (who is Wahoo retailer) and they informed me that they only received a service bulletin related to Kickr/Core compatibility issues on 7 January 2021, which is more than three months after I purchased my Core.

Two months later….. still no solution…..

This article is out now. link to velonews.com

It states that a new adapter will be available in about 6 weeks. Those who contacted support are supposed to get notified. Ray…can you verify?

Oh, my God. Finally!?

Not as of 2 days ago when Lee last replied to me.

Add a 2021 Ribble Endurance SL Disc to the list of incompatible frames….

Long story short, the drive side sleeve hits the frame before it comes in contact with the mech hanger face. requires a further 1.5mm length of the 12mm OD section. ( As pictured )

The whole issue here in my opinion is that they will have to reduce the freehub threads from 5/8″ to a smaller size to allow a smaller OD locknut to be used ( the part with the two flats ) and beef up the internal ( make the I.D smaller ). This would then enable Wahoo to supply a Drive Side 12mm spacer which was 12mm along its OD and had no step ( which is the part that hits my shiny new carbon frame ).

Also, less than impressed by essentially being schooled by Wahoo for not doing my homework first.

How do I travel 200 miles with a Kickr to try it on a bike which the companies showrooms are all shut due to Covid-19. Unless you have forgot, we are in a global pandemic.

C’mon Wahoo, it’s up to YOU to make sure they fit and be up to date with your incompatability list. Also, People don’t buy a brand new bike just for a turbo trainer ( I hope), It’s in YOUR interests that you do your homework and stay ahead of the game.

You’ve dropped a major one with the shaft design and you know it.

First things first, Ray: Thank you so much for this article, it was really helpful for me to aware before mounting the bike on the trainer.

Now, sharing my experience about my bike having clearance issues in the drive side; KICKR V5 arrived today, however, I only opened the box to get out the Thru Axle adapters (C & D) and conducted some tests with them.

I own a Trek Domane SLR 6 Disc 2017; Thru Axle 142×12;

The non-drive side (Adapter D, as referred in the manual) has enough clearance; however I would be worried about the teeth bite marks left in other users here from what I can see in their photos.

The big issue really is in the drive side (Adapter C), which has not enough clearance; the axle actually does not go thru, which clearly indicates an issue if mounting this in the trainer.

Then I did a test using Adapter D, to check how the clearance goes; I was able to pass thru the axle smoothly, which indicates to me, that the needed clearance for my bike on adapter C, should be the same one as in adapter D.

I’ve contacted Wahoo support before and after buying the trainer; I live in MX City, and there was no chance to test the KICKR before buying it; Wahoo did not help much, they only indicated that it was my responsibility ( I fully disagree) to make sure the trainer fits my bike, bla bla bla.

I contacted Wahoo today and waiting for their response , on either providing the new parts or indicating any other option available; I’ll post any updates.

Best Regards.

Any update on comparability update with Giant TCR Avanced 3? I just tried to put it on the wahoo kickr core using the 142 non drive side adapter which seems ok but there isn’t enough clearance on the other side. Two considerable chunks taken out of my bike on the drive side. I can’t believe this. I only bought the trainer last weekend and I’ve never had a scratch on my bike. Do you know of any other smart trainers that are compatible?

I feel your pain, I have just done this on a brand new bike.

I got nowhere with Wahoo really. I ended up taking matters into my own hands by first drawing a revised spacers then machining it.

Job sorted, plenty of clearance now

The damage it causes is horrific. You just don’t expect it with a leading brand like wahoo. I hope you get sorted.

Does anyone know of any smart trainers that are compatible with Giant TCR advanced 3 2021 frame? I’ve just returned the wahoo and I’m now left with a few gashes on my frame!

I just received my Wahoo Kickr Core today and noticed when setting up with my Ultimate CF that there was zero clearance between the Kickr and the frame on the non-drive side. I’ve not ridden the bike on the trainer yet and I’m now considering what to do.

All the discussion / images about new adapters appear to be for through axle, while the Ultimate is a 130mm spaced QR. Based on the fit of the Ultimate on the Kickr, I do not believe that there is any way to solve the issue with a new adapter. Basically the frame touches the Kickr even with no adapter fitted, so there is just no space to fix this with an adapter modification!

Caveat that with saying I do not believe there is a way to fix it with an adapter while keeping a strict 130mm spacing. I considered the 135 adapter flip but I don’t like the idea of flexing the stays that much, I might settle on adding 2.5mm of spacers to the 130mm side to end at 132.5mm which will give enough clearance. The alternative is grinding the Kikcr frame but this seems too drastic…the alternative alternative is using my Inflite instead!

Thanks for this article, super interesting. When I contacted WAHOO and linked this article asking for the new parts they just replied saying this is still being look into and they went able to help at this time.

I was close to purchasing a V5 before I stumbled on this article. Here’s an update from a local bike shop as they’ve been in contact with Wahoo regarding this issue for a while. I have a ’21 Trek Emonda SL6-Pro.

“Update from Wahoo – they’re landing the first batch of adapters in the next couple of weeks in Georgia. There were some re-works that the bike brands involved wanted to address, hence the delay. Once they land there they will ship our first round to us. We’re still waiting on an estimate of how many units they will be sending on the first round, but there will be many more to come. We’re also still waiting on a timing confirmation for when they will be included in the box with new Kickrs – let you know as soon as I know. Let you know when we have more info or have some ready to ship your way, whichever comes first.”

Seems the delay might be because the affected manufacturer’s are involved now or more so than before.

May 2021. Wahoo support told me there is no solution to date for my 2021 Domane. I’m confused by conflicting information and frustrated.

This has been an uncoordinated, unqualified, disaster (all on Wahoo’s part).

I received the following response from one of Wahoo’s Support Supervisors last week: “[The adaptors] have now been approved by all manufacturers, but we are still a few weeks from receiving the adaptors at the warehouse and shipping them to customers.”

Thank you so much, Stephen! Nancy

Thanks a lot for the article. I read it ontime, just before mounting my Cervelo S5 current model on it for the first time …phew. I have Cervelo 2019 which is the first year when they started making that new S5 frame, so I think when Wahoo saying Cervelo S5 2020, they mean 2019 and up. Anyhow, called Wahoo tech support today and they said that are in the process of testing and manufacturing those new adapter kits, they are very much aware about the issue. They gave me a time frame that those kits will be definitely available by fall 2021. They took my information and address and promised to send me a confirmation email when kits are ready to be shipped. They will also provide those kits for free.

Lets wait and hope.

Literally so confused about this issue – I have a cervelo s5 2021. Bike shop telling me only 2020 on the list and not a problem, your post indicates 2019-2021 (which makes sense fundamentally the same model). Tested the trainer in the shop with bike doesn’t seem to be any issues, but now wahoo have emailed me confirming 2021 S5 not compatible and I should return the trainer… Extremely confused as to what to do!!

Has Wahoo started shipping the new adapter kit? I have several customers with 2021 TREKs waiting.

No. Although I have read posts by people claiming to have received Wahoo again this week told me none are available. They continue to work on a solution. I’ve emailed support and they are very responsive. They have assured me they will contact me when an adapter is available for my Domane.

This simply is to slow. Same with Campagnolo freehub – no update what so ever. Thx.

I’ve had a very strange experience with their support staff. I have a Domane and I’ve been waiting for their adapters since January. They said they would be available soon.

I don’t get any proactive communication and I follow up about once a month. Most of the responses are bordering on rude/condescending. There definitely isn’t good customer care being practiced.

Do any of you have the same issue with their support staff? Has anyone heard any more detail on adapter availability?

GW – I have a Domane as well, no additional updates. I have also had the same issue with their support staff. Its a shame because it is such a great trainer, but Wahoo has really done a belly-flop on this one…

Hi all frustrated Wahoo users

I just received this from Wahoo, so I thought I would share as its sounds like progress:

Hello! Your order attached to this support ticket request #XXXX has been shipped! Your tracking number is XXXXXXX.

Although when I click the tracking number UPS has no record of the shipment! (one step forward …)

Just an update – correct tracking number received, delivery on Monday 31st! (but the tracking also says its in my home city so maybe sooner).

I never received a tracking number after confirming my address, however, the part showed up quickly after my email exchange. Installed on my trainer the other day.

Juts received an email from Wahoo that they will be shipping me a new set of adapters and its free. In the email they also included a URL to the installation instructions: link to support.wahoofitness.com

Me too, thanks to this thread I registered a ticket with Wahoo in April and got the same email yesterday saying we need your shipping address and the adapters will be shipping very soon! Wahoo!. Great to hear some are shipping already, it helps clarify what ‘very soon’ means!

All thanks to finding this article and thread, awesome.

After my first wahoo catastrophe with my giant tcr 21 frame I am reluctant to buy another wahoo with the adapter. Does anyone have any recommendations for another smart turbo that’s compatible? When I ask the brands they don’t seem to give a definite answer!

Now with the adapters shipping out from Wahoo, should I go for the Wahoo trainer or stick with my first thought and go for the Saris h3 ? Or… ? I have a Trek Domane SLR7 2021 model.

Thanks for the advice

Ok, so parts to solve this compatability issue arrived and been installed and seemed good. Than (after a ride) I noticed that the new axle nut is shorter and does not seem to hold the free hub in place (explains why shifting was dodgy). I have raised a ticket with Wahoo to understand what is happening – maybe i have got it wrong.

Here is a link to a video where i put the old axle nut on – no movement and then the new axle nut and i have about 5 mm lateral movement. can anuone see what i have done wrong?

link to youtu.be

PS – yes i know the cassette should come off to tighten things properly which i had done initially but i didnt here to keep the video shorter

I have the exact same issue with 2017 KICKR. The drive-side adapters are significantly narrower and result in a hub width of < 142mm. There's a 2-3mm gap between the dropouts. Even with the old drive-side adapters in, it is still narrower than 142mm.

Has anybody from the UK received the revised adapters yet?

Mine shipped on Friday and are due for delivery tomorrow.

Greetings all, in the UK and received the new axles adapters this morning. Just fitted to my Kickr V5, very straightforward process and no problem with axle width. My bike’s a 2020 Trek Domane SLR and it goes on nice, with consistent space between frame and the adapters on both sides.

I’d never tried the Domane on my Kickr previously (having been pre-warned), so I was changing bikes, and also from QR to thru-axle, and from Shimano 11 speed free hub to SRAM 12 speed XDR, and unexpectedly, the XDR cassette was too far inboard, a whole gear out of alignment. Now I could have set up the rear mech wrongly, though it works fine on my Hunt wheel, but I just removed the cassette and added the XD 1.8mm spacer and everything is perfect. Slightly odd, but I’ll take that and delighted to get my ‘new’ bike onto my Kickr, finally!

Hi D Ho and others, an update on the incorrect parts that meant the free hub could move with the new parts from Wahoo. I contacted Wahoo (with heaps of information) and they advised that i was sent the incorrect parts – they were prototypes that were not meant to be shipped. They have been really good at sending me another set of parts which I have just received. I have fitted them and they work really well. “Hopefully” you have the same problem.

So if you notice the free hub can move then raise a ticket with Wahoo as they are now aware that they have shipped wrong parts and they were quick to resend the “correct” parts. Good Luck.

Just received the adapters here in Australia. Must say wahoo support has been really good with this. I first contacted them few months back checking re kickr compatibility and Trek Domane before purchasing either. Since the adapters weren’t yet available (nor was there any stock of Trek Domane here) I ended up buying a kickr and a different temporary bike. Recently wahoo contacted me to advise adapters are available, verified my details and sent them down. Very happy with the support. Now if only Trek hurry up and ship some bikes here!!

I just received my Kickr and tried mounting my Trek Domane 2021 model on it with the replacement pieces I had already received from Wahoo upfront. However, the chain is not rolling as smooth as it should be. I purchased the same cassette as the one on my bike to avoid having to change my derailleur set up. I thought it might be an issue with the used chain on a new cassette, but I have now swapped the cassette from my bike to the Kickr to rule it out and have the same issue.

I have uploaded 2 vids and photos of the parts I used. link to we.tl

Did I miss something?

Wow, any prospective buyers of a Wahoo Kickr that own the previously incompatible models AND own compatible QR bikes who ntend to swap them regularly should be aware that this will be a headache for you.

You WILL have to keep reverting back to the original non-conical threaded nut to use your original QR adapters unfortunately.

I kind of understand why they done this, in order to increase the “meat” inside of the drive side adapter due to machining back the outer diameter.

My new adapters went back in the packet and I’m using a custom made EN16T drive & non-drive side adapter which allows the use of the original threaded nut so therefore it’s easy to swap between 12mm thru axle and QR bikes.

Such a shame that the design of the entire axle is gimped.

Is there anyway to use the Canyon Ultimate Rim with a Kickr Core as of yet? Dont really want to use a 135mm incase it strecthes the rear.

I have uploaded 2 vids and photos of the parts I used.

From what I’m seeing in your videos, your indexing is slightly out on the trainer, which is not surprising. I have to re-trim my gear indexing every time I swap between trainer and wheel. This has been the case for me on two different Kickr trainers (2017 and 2020) and two different bike frames, each with different drive trains (make and number of gears), so I don’t believe this anything to do with the new Kickr axle adapters. I put it down to the cassette being in a slightly different lateral position on the trainer compared to rear wheel – I even get this when swapping wheels. I wish the manufacturers could achieve a tighter tolerance and avoid this, but at least with SRAM etap, re-trimming the rear mech is no major hardship.

Pfff that’s annoying. It seems Di2 trimming is more complex than the manual way. Swapping the bike multiple times a week doesn’t seem to be a good option. So I might be looking in a 2nd bike to put on the trainer instead…

Di2 is actually pretty darn easy (short vid below). If you pay attention to your adjustments when on the trainer, place that info on a note nearby, you can easily reverse the settings when you need to pull it off. Maybe not ideal for frequent swaps, but doable and might be “easier” than obtaining a dedicated trainer bike. More than one way to do it, so it’s good to consider the options.

Hi I have a 2016 slx with this issue.. If I flip the adaptor to the 135 side it then requires a slight spread of the frame to make the bike fit. Is anyone actually using the kicker /canyon in this configuration?

I also have a 2016 ultimate slx and I am now wondering which direct drive trainer is compatible with this model. Has anyone tried it with the tacx flux or elite xr model?

I’m new to Kickr with Ultimate 2017 frame. Are you still spreading the frame? Any damages to it?

It may be impossible for trainer manufacturers to test all bikes. HOWEVER, they could do more to help ensure compatibility.

Look at what 4iiii’s does: they offer a PDF template you print and stick to your frame: link to 4iiii.com

Companies like Wahoo and Tacx could offer something like that and simply say “if your bike isn’t on the tested and approved list, print this, measure for 5mm clearance here and here. If it’s less, you need spacer-X. If there’s overlap or less clearance, no bueno, even with spacers.”

Following on from my previous comment.. I’ve searched fir a washer the same diameter as the axle adaptor… Drilled the centre out to 10mm. The washer is only 1.5mm thick.. But added to the 130 side of the adapter it adds the necessary clearance without having to flex the frame outwards and still leaves enough of the axle adapter showing to sit the dropout on. Seems fine after a month or so

Hi. I just bought Kickr Core and luckily discovered incompatibility issues before mounting my Domane. I saw that the easy fix is removing 6 mm of material from 142/148 mm adapter but my question is if anything should be done also to driveside adapter? Replacement set has both parts different than original ones and I wonder if grinding one adapter is enough to solve problem.

This has really helped me out. I never had issue with my old dumb trainer – even fitting kids bikes to it was easy – but I found that I struggled with fitting bikes to my Kurt Kinetic R1 and my Bkool Smart Air. To make the kids mountain bikes fit I resorted to removing parts of the plastic housing from the trainer and I bought shims to take out the gaps. For the kids MTB I also had to remove the rear disk calliper!

I felt like I shouldn’t have to do it and worried that I could be causing more problems, but I tested it pretty well and so swallowed the worry carried on.

I feel so much better knowing I’m not alone. 🙂

Ok!! I wondered about this. Just requested my parts for my Madone SL7 2021.

Thanks for the article. I’ve written a big letter for you to see if I’ve done right. I’m attaching the letter. If I have done right, please consider modifying your article to show that we need to turn around the non drive part and use force to put the bike in. This way all will be clear and no questions will be asked.

Thanks again Moshik.

Hmm, the letter didn’t come through. The site will show previews of images, but not things like PDF’s. You can also just include a link if you want instead.

(As long as there’s just a single link, it won’t generally get hung-up in my spam pending box)

Sorry for that. Here is a link to my google drive. In general – after doing everything I found out here I need to use some force to put my bike in. Is it supposed to be like that? link to docs.google.com

I have a business proposition for you regarding this issue. You have my email so can contact me there.

Thanks for flagging this. I have a 2021 Canyon Ultimate CF SL 8 with rim brakes, and I am having the rubbing issue.

But, now I am confused, because my bike does not have a thru-axle, so I had used it on the Kickr with the standard 130mm quick release skewer. If I change my Kickr to the 142 thru-axle setup, that would make it too wide for my bike, right? Do some Ultimates come with quick release and some with thru-axle? Or am I missing something?

Hi Ray, Thanks for this! I just got my bike tuned at my LBS and they said they noticed something during the tune though both mechanics said it was likely safe to ride. I looked when I got home and saw that the rear stay on the NDS had been chewed away a bit by the rubbing against the Kickr Core I have. I did some googling and here we are. I’ve put thousands of trainer miles on the bike/trainer combo (had both since April 2020) and I am worried my bike’s integrity is impacted. Seems like neither Canyon or Wahoo will help me out and I feel like it would be bad karma to try to sell the bike, but the bike seems okay…It doesn’t seem like the new adapters will help as I have a QR…I just spun the adapter around as you suggested and got the bike back on the trainer successfully and did a ride but as others have asked, does stretching the rear stays like that cause any issues?

I was having a similar issue (as per my comment above) and what I ended up doing was using an angle grinder to grind down the black ring on the Kickr that was making contact with the chainstay. The Kickr was already out of warranty, and I can’t see how the modification I made to the Kickr could have any downsides to its integrity, especially since my 5-second sprint tops out at a paltry 700 watts :)

Hi there, I recently bought the Kickr Core and have attached my Canyon Endurace 2022 bike to it with the 130 mm thru-axle adapter that came with the Kickr. It seems the rear of my bike only rests with half of the frame on the 130 mm adapter. Tried using the 135 adapter, but that one is way too big. Seems like the size of the 130 is fine, but the adapter end is just quite small. Anyone with the same ‘problem’ or is this normal? Thanks again!

Amazing! Thank you so much for clearing this. I have the exact same model of Canyon Ultimate. I can now buy Kickr without worrying that I might need some adaptors to make it work or damage my frame.

Hi I found a solution to the problem. It will require some footwork from you. The issue is that one side of adapter one makes the frame touch the Kicker and when using the other side I need to apply force to spread the rear fork to get the bike in. I went to a friend of mine that had a CNC machine and he created a few washers for me. I applied the washers on the adapter and this gives me enough clearance so the frame does not touch the Kicker and the bike go in smoothly. I also don’t do 1000 watts sprints on the Kicker Hope you find this solution useful. Moshik

Thank you, thank you, thank you. 2018 Canyon Ultimate CF rim brake.. has been hanging from the wall lording it over my Steel Gravel/Winter bike for a very long time. A mechanical mid zwift race yesterday meant the MTB went on the trainer, which was painful to say the least. Got me thinking if there was anything I could do to make the Canyon compatible… and turns out it is! TFFT. Cheers DCR.

Anyone with a wahoo kickr experience this shifting issue?

• Add to quote

If this is the wrong forum I'm sorry I recently received my new wahoo kickr and got it set up last night. I verified my bikes hub is 130mm. (Trek Emonda SL6 Pro, Vision Metron 40 wheels, 11-28 11 speed ultegra cassette). When my bike is properly mounted, my shifting is not proper. I cannot get into my largest cog in the back, and if I shift past the smallest cog the chain will shift off the cog itself. And during the rides the chain can be noisy in some gears. My bike shifts flawlessly on the road with my wheel on, is there anything I can try to get my shifting to work properly? Thanks  

What cassette do you have on the Kickr? I would try to match the cassettes.  

It's an 11 speed as well, as far as the gearing im not sure and I haven't found online that specifies that  

I know nothing about the KickR but it sure sounds like the cassette is positioned differently on the KickR. I believe you need a shim to use the Kicker with 9 and 10s cassettes. Could it be that you have a shim installed by accident with your 11s cassette?  

jeri534 said: My bike shifts flawlessly on the road with my wheel on, is there anything I can try to get my shifting to work properly? Click to expand...

There may be a slight alignment issue. 1. Prior to mounting the bike on the kickr, make sure your bike has been shifted to a cog 5 or 6. I would keep the chain on the biggest chain ring. 2. Make sure your qr axle is not bent on your kickr. 3. Make sure the through axle mountin bike adapter is pressed in fully. 4. Place the bike on the kickr straight down. 5. Make sure the rear of the bike is flush down into the trainer, sometimes it helps to remove the little springs on the quick release axle on the rainer. 6. Tighten the quick release. 7.With your hand just hand pedal for a few cycles. 8. as you are hand pedaling shift your gears, first all the way to the largest cog, then all the way down to the smallest cog. 9.If its not going all the way to the largest or smallest cog, 2-3 turns on your barrel adjuster may be required. While the cassette is for an 11 speed drive bike i have noticed there is about 1 to 2 mm difference from when my bike is on a wheel versus when it is on the kickr.  

But the short answer is after its mounted you adjust the barrel adjuster for your rear derailuer.  

Just like putting a different wheel on a bike, you should be checking and adjusting your limit screws and adjust the cable tension to get the shifting dialed in with any wheel off trainer.  

So I took the bike off and checked everything over, remounted it and it is now working great. Must have been misaligned when I initially installed thanks for the replies and suggestions  

That's good, because you should never need to redo limit screws and play with barrel adjusters for the equivalent of a wheel change. Anyone who says otherwise probably shouldn't be giving mechanical advice. Sent from my XT1049 using Tapatalk  

I have the same issue and likely the cassette on the Wahoo isn't exactly "right" but I just turn the barrel 4 clicks when I put the bike on the trainer and 4 clicks the other way before I hit the road.  

I realize this is a bit old, but.... I had the same problem with the Gen1 Kickr. Using the 130mm setting, if I looked carefully, when tightening the quick release, the rear triangle was getting squeezed enough to mess up the shifting. Could possibly also account for the few instances of people whose carbon frames have broken(?). I flipped the little adapter thingy to the 135 position and voila, no more compression or shifting problems and no trouble getting the bike into the trainer either. I wonder if the Gen1 adapter is off a bit. But yeah, in/out of the trainer, you shouldn't have to adjust the RD at all.

All-new Trek Emonda ALR takes lightweight frame tech to alloy models

• Click to share on Facebook (Opens in new window)
• Click to email a link to a friend (Opens in new window)

When Trek announced their Emonda carbon road bike line , they backed up their “world’s lightest” claims with an impressive frame and fork and an even more impressive 10.25lb (4.6kg) complete bike. Now, they’re adding an alloy Emonda ALR option that’s also lightweight yet far more affordable.

To earn the Emonda badge, the frame uses their top-level 300-series Alpha Aluminum that’s been hydroformed into size specific tubes, then welded together using a no-see technique that produces smooth joints that use less material to save weight.

The process is called Invisible Weld Technology, which they say produces stronger, stiffer welds despite using less material. Video, pics and more details below…

Trek told us the unpainted frame is 1050g (56), and a painted fork is 358g w/240mm steerer.

Like the ultralight Emonda carbon models, the ALR uses their H2 race geometry, E2 tapered headtube (standard 1-1/8″ to 1-1/2″) and wide Pressfit BB 86.5, meaning this bike is made to go fast. Other frame details include a braze-on front derailleur mount (no need to add a clamp if you’re getting the frameset) and external cable routing.

We’ve requested a more technical description of the welding process (update as we get it), but the frame is only part of the story. The complete bikes come equipped with built-in extras like the a Blendr stem with integrated light/computer mount, and it has Duotrap S compatibility (their ANT+/Bluetooth 4.0 speed/cadence sensor, sold separately for about $60).

You also get a complete group, so the Emonda ALR 6 with Ultregra gets a full Ultegra group from chain to brakes to cassette and everything else. There are no mis-matched parts or down spec’d bits to cut costs. A full carbon fiber tapered fork completes the package.

The Emonda ALR will initially come in two builds, the “6” with full Ultegra, Bontrager Race tubeless ready wheels with R2 tires, and a Bontrager cockpit with alloy short reach/drop bar and carbon seatpost for $2,249.99. Our local Trek Bike Store says complete bike weight is claimed at 17.25lb (7.82kg).

The Emonda ALR 5 drops down to a full Shimano 105 group with non-series Bontrager tubeless ready alloy wheels, R1 tires and a full alloy Bontrager cockpit for $1,759.99. Claimed weight is 18.77lb (8.51kg), colors will be the gloss black/hi-viz yellow and blue shown here, plus a racing red coming soon.

The frameset shares the same paint scheme as the “6” and comes with an FSA sealed cartridge bearing headset for $989.99. The frames have a lifetime warranty carrying a 275lb rider weight limit.

Just for fun, here’s the companion lifestyle video.

All three models shown here are available now and should hit stores soon. Our sources tell us there’ll also be an Emonda ALR 5 with Tiagra, an ALR 8 with Dura-Ace mechanical and ALR 9 with Dura-Ace Di2 coming soon. That last model suggests they’ll have an electronic-only frame, too, since these first models only have external cable routing. At the very top, in terms of light weight anyway, will be the ALR 10 with a full SRAM Red group.

looks like a rebadged Allez

The invisible welding looks a lot like what pretty much every other company calls smooth welding. And has been using for years. You weld the tube normally then go back over it without filler material and “reweld” it. The process smooths out the weld and helps it wet out. REVOLUTIONARY TREK!!!

Interesting that they are using hydroformed tubes but didn’t choose the aero tube shapes of the Madone design.

@Robert W – my sources say the Madone is on the way out. & if the story is about weight vs. areo it would make sense to mimick the emonda shapes. Also, the 2 series aluminum frames are already Madone-esqe.

I always find it funny that companies state how they’ve extensively optimized tube shapes for their flagship carbon fiber bikes, but then seemingly can successfully apply those shapes to materials with very different properties. There is a little marketing lie in their somewhere.

Anyway. Glad to see these Al bikes. CF has been getting too pricey fort me.

I like how they quote an unpainted frame weight, then only offer it in a painted variety. But lets also make sure we pair that unpainted weight with a painted fork weight.

Looks legit. Seeing they are coming out of the Giant factory why not put on the overdrive 2 fork and stem and really take it next level?

Aluminum, how quaint.

Why not sell them unpainted if they weight them unpainted? JBikes if I read you right what your saying is the shapes have far mo9re to do with design than engineering.all thes tube shapes are probaly coming from kitchen appliance design firm and they bs riders who rarely go over 20mph that aero is worth buying a new bike for

That Bontrager cycling kit is pretty damn nice. “Understated” as the hipsters like to say.

How about US made aluminum, with giant tubes, some internal routing, and some really funky paint jobs. Oh wait…

Hasn”t specialized already been doing this for like 3 years now? And better welded joints? Revolutionary-nothing is more like it, just another slightly modified copy frame.

Roy – no I was just commenting on the fact it’s stated how non aero tube shapes are optimized for carbon fiber for whatever properties (stiffness, weight, ride) but then a vastly different material can achieve the same with the same tube shapes? I’m sure they vary material thickness and such, but given the vast difference in CF and Al, I’d think tube shapes would vary more between the two materials, unless the CF and Al frames ride completely different.

Jesus, tough crowd. Lightweight aluminum, full component groups and small price tags… Sounds good to me.

Full Ultegra! Well… except the wheels. Of which, the Bontrager Race spec is a few notches below Ultegra…

y’all are haters. you can pick on the marketing and on random bits and pieces but in the end this is the bike you’re going to start seeing at all the local crits and races. So they have weird marketing, worry about the bike and what it can do for you.

Aluminum is the new carbon.

Yeah a bunch of haters here, Go buy a Specialized because they are not owned by the big man, Oh wait, Specialized is own by a conglomerate, and Trek is family owned. Seems like most people don’t understand the definition of “the man” Don’t hate on them just because you don’t like it that more people ride Trek than any other brand in the US.

@Durianrider, you’re killing me! Lol

When you think about it, it’s a bike people actually look for: Workhorse, and the no-nonsense but clean aesthetic.

Considering the Propel SLR might not come stateside, as well as the update TCR SLR before it, it’s nice to have another potential alloy option on the market that isn’t an Allez or CAAD.

I really like where Trek is going with their new paint schemes. Very minimal branding and no stupid racing stripes and decals. Keep it premium!

Jbikes: I understand why you’re asking about why two frames with different materials have the same tube shapes, but in fact they probably should have the same shapes.

In the bike industry (and many others), it’s common practice to design using isotropic material properties (e.g., with aluminum) for a first pass. The resulting stiffness (quantified through FEA) ensures you’re getting the most sectional modulus you can out of a given tube shape. Only then do you go back and design a laminate schedule with anisotropic materials (e.g., carbon fiber).

This allows the designer to clearly separate the modulus (stiffness) due to tube shape and the modulus due to the laminate schedule. That way, each can be optimized as a discrete step.

Except for a few corner cases, optimal frame tube shape is material-independent. Surprising but true!

Looks like a great bike at a good price. I love nice aluminum race bikes. But why no H1 geometry option? It irks me that companies (not just Trek) spec the really race oriented stuff at the high-end of the price scale. I know a short head tube doesn’t work for everyone but why not give us the option? What does the size of your wallet have to do with your flexibility?

I’m wondering if some of the frames are anodized, so unpainted weight would be pretty relevant.

JasonK – thanks! Great info. Never really thought of it that way but it makes sense.

I like the emonda and the CrossRip frame for my commuter. I would seriously consider if I was in the market and carbon was not an option.

Man that’s a light frame. Nice to see they are using full groupset specs.

I wonder if the welding is a form of aluminium brazing using a lower melting temperature brazing rod. I think this is what Shimano do with the external reinforcing tabs on the aluminium rims. This is supposed to be lower strength than welding but coming up with some newer technology is not beyond Trek’s resources. Or maybe they have come up with a way to modify the pulse action of a TIG welder with a certain filler wire application. Either way, the old double pass method for aluminium is old hat now.

Most companies claim unpainted frame weights. Use this general guide: If a company says “…painted frame weight is…” then it’s including paint. If they don’t specifically say painted then you can guarantee it’s an unpainted frame weight.

The only reason I wouldn’t buy one of these is the head tube is too tall…

I applaud Trek for coming out with a ‘light’ and ‘inexpensive’ aluminum frameset but I’m still not sold on the H2 geometry.

Sincerely, Worlds longest head tube.

I like the option of a high end aluminum frame as well….but this one misses the mark for me because trek refuses to make any bike with its “racer” H1 geometry that doesn’t cost at least 4,500 for a frameset. If they only would make H1 options of their emonda sl frame or this new all I’d buy one in a second. Trek already makes a million bike models….why not better fit options? Ever since they did away with the 6 series madone the options for the budget conscious racer have gone to zero. Bleh. And more seatmast length options trek!

Nearly the same weight as a Cannondale frame that was first manufactured out of the same material about 6 years ago

I think this will make a GREAT race frame.

Certainly beats trying to replace a carbon frame someone broke for you in that ‘last corner of the criterium’ crash.

If I see one more I’m-so-flexible-I-can-stick-my-head-up-my-ass comment about the lack of H1 geometry, I might give up trolling comments on bike rumor all together. Seriously, 5 years at a Trek dealer and we sold maybe 3 H1 bikes (all as special order). We ordered dozens more project 1 bikes in the ‘normal’ H2. Working now at a Cervelo dealer I have very few people balk at the head tube height, and MOST are running a positive angle on the stem anyways. At 6’3″ I run 14cm of bar drop. I have had zero issue getting a proper fit on stock bikes, including Trek. Currently on the newly updated (i.e. market norm) stack of the 2015 Cervelo S5 I still have 15mm of spacers under my stem. If H2 geo just doesn’t do it for you, grab a Cannonade with a low profile headset cap and go ride. They are making a bike for the largest market, obviously the budget racers this bike is designed for are too busy riding their bikes to complain on Bike Rumor…..

Looks like a great bike for the money and your avg rider. Nothing wrong with that. Kudos too for specing a complete group build, awesome!

Waiting for my ALR 5 to arrive!! Last bike I bought was in 1986, a Myata One Ten. Hopefully this one will last another 29 years.

uhhh… the allez actually looks good

http://www.specialized.com/us/en/bikes/road/allez/allez-comp-race

the only thing actually missing from these frames are some colorway options like the tarmacs

i had a domane and the headtube was too tall.

i might get one of these. its pretty affordable all things considered.

There doesn’t seem too much, if anything at all, to complain about here. The Emonda ALR frame MSRP is right in line with a CAAD10 frame MSRP ($10 cheaper actually). It looks good, and it’s certainly not a heavyweight bike. If it rides as good as it looks, it will be a great deal.

@MikeC – Are you kidding? I haven’t seen anyone refer to a full groupset as including the wheel since like 1999. Some people are just desperate to find something to bitch about. The Bontrager Race wheels are great. They only weigh 200g more than the Ultegras, and unlike every Shimano wheel, they are specced completely with off-the-shelf parts that are easily purchasable in any bike shop.

@Adam – Yes, because Cannondale were the first company with an aluminum racing bike. You forget the Trek, via Klein, were making awesome lightweight aluminum race bikes when Cannondale was still welding together soda cans.

@H1 Lovers – You’re all on crack. A quarter of the Trek pros don’t even ride the H1, and I promise you that you are not that fast. I can also tick off a list of local heroes, Cat 1 and PRO dudes, who get by just fine on the H2, usually preferring it to the H1.

@Psi – And the Trek is clearly much better specced than the Cannondale, with an Ultegra crank and Bontrager Race wheels, not to mention a cockpit that won’t require immediate replacement.

Wait to you see the next gen cannondale frame before you jump on this..

I am happy this exists. Buyers beware if you crash this thing it’s probably going to dent up like tinfoil.

@badbikemechanic – What makes you say that? There is a generation of high end aluminum out there that holds up just fine to the rigors of daily life. I personally have an aluminum Allez that I regularly leave locked up outside of bars, the grocery store, as well as race, and it hasn’t even scratched the anodized finish yet.

As always, opinions abound….and everyone is “right.” The H1 vs. H2 debate is clearly a hotter topic than I thought. What it boils down to though is “choice.”

Trek offers the option, meaning there are people that prefer it. I rode a 60 cm H1 Madone 6 series last year, and absolutely loved it. Sadly it was a team bike and I had to give it back at the end of the year. In looking for a replacement I want a bike with similar geometry, but don’t want to spend 4,500 to have the OPTION to get the geometry I like. The head tube on the H1 is 18 cm…compared with 21 cm on the H2. That is a LARGE difference. I don’t think anyone is right or wrong to ride whatever geometry they like. All I’m saying is that for me…the H1 geometry is perfect, and I don’t need to run a -17 stem to get my preferred position of the bike. Being a pro, being fast or slow, is irrelevant. I would just like to see the option available at a reasonable price point.

These bikes are epic. And yes, they blow the competition out of the water.

About time Trek offers something for the Joe-Racers out there. Yes, carbon is super nice but you guess what: so is aluminum. I have a locally-made Aluminum bike and it rides *amazing*. So did my old Caad7 and I bet Specialized’s aluminum bike is also fantastic. We need more people in the sport, and to do that we need a much lower entry-level bar. if for $2,200 you get a nice Al Trek with good geometry, good wheels (i own the bontis tlr and they’re indestructible and readily serviceable), good parts and cockpit that are either race-ready or hammer-ready, then god bless Trek. For the record i own a cannondale six and it’s a phenomenal bike. but my aluminum rig is my favorite. way to go, Trek – kudos indeed.

Arguing that “some pros ride H2, therefore nobody needs H1” is well, just a poor excuse for an argument. An H1 aluminum Emonda would be a hit, and I would purchase one as soon as it were available. I’ve owned and ridden both H1/H2 models, and greatly prefer the H1. As an aside, direct mount breaks on this beast would be the icing on the cake. Think about it Trek.

This bike compared with the new caad 12 is nothing …

I’ve got a current model year Allez smartweld frame built up with full 105 and tubeless Shimano wheels. I certainly didn’t do it for $1760 retail, but then some parts on my bike (bars, saddle, tires) are from a very much higher trim level. I’ve also got all the accessories (cages, tools, &c) in my price, and I was unable to use the economy of scale a manufacturer can.

ANYWAY. The ride quality of my Allez is nothing short of amazing considering. It is *as smooth* as my steel 3-speed with 38mm tires over brick roads. I have no problems riding the Allez a hundred miles, though I run out of water. The Allez smartweld is making me completely re-think aluminum as a frame material, especially for amateur racer types.

These Treks seem to DIRECTLY compete with the Allez smartweld introduced last year, which is great, since it engenders competitive designs. When you get an Allez Comp (with 105), you pay less, but you miss out on the excellent 5800 brakes and crankset, and get bog standard training wheels. Moving up to an Allez Expert (with Ultegra), gets you a full groupset with carbon SL-K crank and ‘Fulcrum’ wheels at a competitive price.

I’d love to ride these Treks back to back with my Allez.

I am happy to see Trek jump into the “high end” aluminum market. I have owned & loved several iterations of CAAD’s. I have also read good things about Specialized redesigned Allez frames. I am now hearing of a redesigned CAAD12(?) to be released later this Summer…(anyone else hearing any details?) I would have liked to have seen a disc version from Trek… (Spec as well.) I believe that road disc offerings from every manufacturer will increase exponentially once the pro’s are riding them. I wanted my next road bike purchase to have discs so that I can look for second set of wheels that will be future proof…(thru-axles coming next?) I had my eye this year’s CAAD10 Rival disc, hoping the boys at Cannondale offer an Ultegra disc spec on the CAAD12 later this year. 🙂

Just ordered my alr 6 today! I work at a trek dealer, and I have to say H2 is usually great for 99% of our customers, and they usually have the stem flipped up. For the 1% of people that actually want that huge bar drop, you can always size down and make it look super pro with a longer stem! Nothing wrong with that!

Wahoo Kickr Core incompatible with Trek Emonda 2021

Received this from Wahoo re producing a new adaptor:

“This is something we are looking at however, we do not have a timeline for this and will likely have news in the new year.“

Seems slightly less hopeful than feedback others have received

You just need 3 minutes with a bench grinder or maybe 20 with a hand file.

I’ve used the nut and bolt method suggested with a cheap hand file and the outcome is actually not too bad…

Unfortunately I’ve also realized too late this issue and the damage to my new TCR frame is done, hopefully someone out there can advise if it’s serious or just cosmetic…

I don’t think the honing oil or stone are required or even helpful.

The file should work, although I think a flat file might be more appropriate and a bit easier to use. It looks like you’ll have to take a fair bit of material off, so a handle for the file would be helpful too.

I did it with a file. Will send pictures when I get home

I tried the drill thing. Ate through my file, not the adaptor. File only worked when I did it by hand… what did you use to cut it down?

I’ve used a standard double-cut flat file, you can see it on top of the tray of my bike stand in the picture… did you use a single-cut file? These are supposed to be only used in a certain direction and if used in the wrong way will dull the file and not the metal.

Damn… didnt know about double / single cut files

Wahoo has finally updated their site, but it now just has an asterisk for the 2021 models that were previously listed as incompatible, and it says " **Additional adapters may be required, please contact customer support for further inquiry.*"

https://wahoofitness.yonyx.com/y/conversation/?id=c6a3c220-be88-11e7-b908-bc764e10c19d

I’d be willing to bet that’s just cosmetic, but maybe get it checked.

Thanks, I submitted a ticket and will report back

UGH - Wahoo seems to have removed the update about the adapter form their site, it’s reverted back to just saying it is incompatible. Additionally, I received two conflicting responses from them.

From December 3rd: "We have now confirmed with trek that the AL domane will work with the kickr (as per their support staff). Please still exercise caution when using it, however according to Trek, the frame should work. "

And from today: “Thank you for contacting Wahoo. Currently, the 2021 Trek Domane is not compatible with the V5, 18 KICKR or CORE. In partnership with Trek, we are actively investigating potential solutions to the incompatibility issue, but we do not have a timeframe for this yet.”

You can get your compatible axel adapter here

Just like some of you I got my bike and trainer without reading the fine print

Does anyone know if the Wahoo 12x142 thru axle adaptor will resolve this issue for the Kickr core, or is it just not compatible at all?

Wahoo got back to me again… changing their mind for the 4th time. Looks like AL models of Domane are in fact OK to continue using.

While I see that its difficult to guarantee compatibility for all bikes, it wouldnt be that hard to make adapters that would fit 99,9% of all bikes. Seems to me like hub manufacturers is pulling it off.

The Wahoo adapters is just a result of an extremely poor design, because they are trying to save money on making one adapter work for both 142 and 148 spacing.

The same goes for the Tacx Neo where allmost all Shimano road disc brake calipers rub or have allmost zero clearance against the trainer.

I got a reply from Wahoo saying that they will be releasing a new adapter in the coming months.

In the meantime I think the easiest option is finding a machine shop or ordering from ebay

Hi all. Saw this thread and seem to have the same issues with my Emonda…

I emailed Wahoo and they said “unfortunately, as for now, there is no workaround for this incompatibility issue, we are very sorry. The issue is not with the Thru axle, is with the geometry of the frame’s dropouts.” and that there is no ETA for a fix.

I bought one of the machined adaptors from Ebay so will see how that works!
