2022 Trek Speed Concept SLR 7: The Basics

We dig much (much) deeper into each of the features on the 2022 Trek Speed Concept SLR 7 in our extended review here , but let’s take a look at the basics you need to know about this bike. For our review, we rode the baseline SLR 7 Ultegra Di2 version, but the framesets are the same from the SLR 7 to the SLR 9 Dura-Ace. First, Trek has finally upgraded their slightly long-in-the-tooth Speed Concept line with disc brakes—which were a long time coming. They’ve also ditched the monopost aerobar riser for a two-post system and much-simplified front end that’s incredibly easy to work on (for travel, fit, or even general maintenance).

The new Speed Concept also has the fascinating IsoSpeed suspension system that’s meant to remove vibrations from the road into the rider—reducing fatigue for the bike and run. Trek has also improved aerodynamics by a claimed 16 minutes over 112 miles (or 16 watts at a Kona-winning 26mph average pace— here your mileage may vary, a lot) and somehow kept the weight below 20 pounds for a size medium with all hydration and storage removed. This is no small feat, by the way.

2022 Trek Speed Concept SLR 7: What We Liked

Trek did a great job with this big Speed Concept update by simplifying where they needed to (the front end, assembly, etc.) and making some pretty interesting improvements elsewhere (the IsoSpeed suspension, the integrated tool kit cleverly housed in the downtube, monstrous, organized storage in the top tube, etc.).

As such, Trek rides the fine line very well between features and real-world usability. But the thing that truly stands out on this bike is the ride itself. It’s rare to find a bike that handles intuitively—even on the first ride—cuts corners tightly, without being twitchy, and actually jumps when you stand up. Sure, killer sprinting isn’t going to win your next Ironman, but it does make riding it much more fun than some wobbly noodle. This is a bike that’s not only a blast to ride, but it’s light weight, and solid feeling—things won’t be rattling off this bike, nor do you need 100 allen wrenches of varying types from microscopic to star-shaped.

2022 Trek Speed Concept SLR 7: What Could Have Been Better

One of the biggest flashy features I was excited to try on this bike was the otherwise omnipresent IsoSpeed that Trek has been using on its various road lines for years. It all makes sense for triathletes—less vibrations mean less fatigue, less fatigue means a better ride and run, especially over long-course distances. Sadly, the unadjutable IsoSpeed only handles high-frequency road chatter as good as most well-tuned double-diamond bikes, but medium- to low-frequency bumps and jolts still hit. Technically beam bikes like the Dimond, Ventum, or Cervelo PX-Series have been using suspension, but the new Speed Concept is singular in the double-diamond world. Make it adjustable (like many other Trek bikes), and maybe it’ll be better, but otherwise the Speed Concept was a little jarring, even when compared to something like the Scott Plasma 6 or the new Quintana Roo V-PR.

There are a few other nitpicky things potential buyers should probably know, but I’ve covered that in more detail in this extended review .

Conclusions

This is a great bike on a long-needed upgrade to a well-loved line. As a gear editor who has to assemble, adjust, ride, readjust, ride again lots and lots of supercomplicated superbikes, it’s a joy to quickly assemble and adjust a new bike that’s actually fast and (mostly) does what it says it will. I can’t oversell how much fun this bike is to ride—as a quick, tight-handling setup that draws similarities to most people’s (and brands’) benchmark favorite tri bike, the Cervelo P5. Both bikes are UCI-legal, still have tri-specific details, are simple in their design, but well thought out, and extremely effective in their execution. I expect most of my big complaints (above) and little complaints (this review) can easily be ironed out in future iterations, so I’d still recommend this upgrade to anyone—particularly those Trek owners who have been toiling with rim brakes, brake-caliper cowlings, and wacky front ends.

I've found one in stock in the SL7 trim (Ultegra DI2) the claimed weight is 8.47 kg for size 56. I dare say, this is a lot of weight for a bike in this price range (and I am looking at an even larger frame). I know about isospeed but I'm nut sure if that's enough to justify the extra weight. Are there any other redeeming qualities that you would make you consider this bike / frame?

Road Tested: Trek Speed Concept SLR9

Bicycling Australia’s fast man Luke Meers road tests one of the quickest bikes going, Trek’s Speed Concept SLR9.

Who likes to go fast? I have both hands firmly in the air. There aren’t too many things that feel better than propelling yourself along at significant speed on a bicycle. Whilst I normally exist purely in road bike land, I occasionally dabble in time trials (I do own an older Cannondale Slice).

So it was hugely fun to get to ride around the top of the line Trek Speed Concept SLR 9; a machine dedicated to compromising nothing on the way to achieving high velocity. I do feel at this point I need to acknowledge that this bike is marketed towards triathletes, which I am not. In fact, I often take much enjoyment in giving my triathlete mates a hard time about (insert standard tri-hard cliche here).

But in terms of Trek’s marketing/design, it makes sense, as by far the largest portion of time trial bike purchasers are triathletes. So there are some features of this bike that are really specific to that market, and while I’ll mention them, they won’t get the same focus as they would do if I was a non-sock wearing cyclist.

The Bottom Line

So, first things first, what do you get for a bike that sets you back the price of a small car (~$18,000)? Essentially, you get the best of everything: top of the line 800 Series OCLV Carbon frame (more on this shortly), 51mm tubeless-ready Bontrager Aeolus RSL wheels, and the new Dura-Ace 12 speed groupset.

There are other significantly cheaper models in the range: the Ultegra equipped SLR7, for example, will set you back just under $13,000, or you could buy the frame on its own for $7,000. Still significant amounts of money though.

A quick run through the standout features of the Speed Concept frame. Firstly, this design just looks nice and looks fast! The profile of the tubes [Kammtail Virtual Foil (KVF)] combine with the dropped seat stays and chunky top tube all combine to give the impression that this bike will be quick. The figures from Trek (always take the manufacturers testing numbers with a grain of salt) seem to confirm this. 

Faster Than Ever

The aerodynamic wind tunnel testing puts the bike faster at every yaw angle than the previous model at what seems to be an average saving of 16 watts (at ~42kph). This might not sound like much, but given that it is compared to an already very quick frame, the numbers seem impressive. It would be interesting to see some independent data comparing the SLR 9 to its competitors. 

Some of the aerodynamic efficiency of the bike comes from fully integrated componentry, meaning no random cables producing drag. This is coupled with the kammtail tube profiles, which seem to be widely accepted now as the best way to balance the needs for aerodynamic flow and tube structural strength. 

The back end of the top tube increases noticeably in depth. In small part, this would be to help airflow to stay laminar as it transitions from the top tube to around the seat tube. But, more significantly, this area houses the “Isospeed” feature of the bike. Some people would be familiar with Isospeed from some of Trek’s other bike models. It is interesting to see comfort being prioritised in a time trial bike. 

The logic is sound though: if you are comfortable, you can ride faster. In this iteration of the shock-absorbing tech, Trek has moved the pivot further in front of the saddle and an elastomer insert provides the shock and vibration absorption.

This effectively decouples the top tube from the downtube, in theory allowing more compliance without sacrificing the efficiency of power delivery.

While on frame design, one obvious triathlon-based feature is the feed storage area included in the top tube. It was a little disconcerting at first having an “open” section of the top tube, but as I wasn’t using it, after a while I forgot it was there. Another nifty integration is the in-frame spares/tool storage built into the down tube.

In my opinion, one of the best things Trek has done with the Speed Concept is the level of customisation and adjustment of the cockpit. Almost every part of the front position of the bike is highly adjustable. ‘Stack’ has 115mm of adjustment, ‘reach’ has 160mm, ‘pad width’ has 120mm and extension length 100mm.

These numbers combine to ensure that almost any rider should be able to find a fairly optimal position. While I’m sure it isn’t as good as getting a custom 3D-printed cockpit, it is a very clever little system to allow the amateur to play with finding the position that works best for them.

Wind Tunnel CFD Tested

While this can all start to sound a bit like an advertorial, a list of things that sound good in theory, I was impressed with Trek’s method of testing and developing the features. They used the obvious technology of computational fluid dynamics (CFD) and wind tunnel testing. It boggles my mind though that companies often seem to do these simulations/tests without including the small fact that there is a person that sits on the bike in real life. 

Trek used virtual and real mannequins mounted on the bike to ensure that their design works optimally with the human body and that the combined airflow around the bike and body is optimised.

While I’m sure there are still compromises and assumptions that went into this process, it seems like a very logical inclusion that has often been overlooked in the past.

So many features to talk about, but how does the thing ride? That is the real question. I can’t comment quantitatively about speed and watt savings (although I did take a few Strava KOMs during testing). 

Qualitatively, the bike does just feel really fast. Speed is often so subjective in terms of feeling, so I won’t try and trust my own sense with this. Rather, I’ll talk about some other aspects of riding the Speed Concept.

The thing that struck me the most during testing was how comfortable I felt on the bike. TT bikes are not renowned for comfort, but I felt really secure and confident in my position. This was despite not really getting to properly play with dialling in a position specific to my body. I was able to put out power well above threshold levels while feeling steady and “locked in”.

From a performance point of view, I’m not sold on the idea of disc brakes on TT bikes. They seem a little unnecessary and like they would compromise the aerodynamics and weight. 

But Trek claim to have cleverly optimised the design of forks and wheels to mean that only 170g of weight is added by using discs, instead of a more normal figure of 400-500g. Despite my disc aversion, I did appreciate the sense of secure braking that they offered. The Dura Ace brakes were really beautiful.

“…The logic is sound though: if you are comfortable, you can ride faster…” Luke Meers

The other thing that was just amazing was having my first ride on the new Shimano 12 speed. It got a lot of hype on its release, so I was interested to test it out. While testing a groupset on a TT bike doesn’t give a like-for-like comparison, I was super impressed with the new Dura Ace. Shifting was simply flawless, both front and rear, noticeably quicker than the 11 speed and very smooth!

I wouldn’t quite say it was unnoticeable, but it wasn’t far off. Shimano’s top-end groupset undoubtedly is responsible for a decent part of the bike’s hefty price tag, but it really is an amazing piece of evolutionary engineering.

One little gripe I had is that the aero drink bottle was completely useless. Maybe the one I got was faulty, but essentially the valve didn’t work at all. I’m really hoping this was an outlier of the production run of these bottles. Also, putting the bottle back into the custom holder could be a little finicky at times.

Overall though, the experience of riding this bike was fantastic, it felt fast, secure, sure-footed (wheeled?) and like the only thing holding me back from going faster was my legs. I really looked forward to every ride on it. I’m sure for the avid TT rider or triathlete willing to invest, the Speed Concept would make a very suitable companion on the journey to speed.

“Value is a state of mind”, or perhaps “value is in the eye of the beholder”. At least that might be what you’re saying to yourself when spending north of $18,000 on a bike. While that certainly is a lot of money, you are definitely getting a lot of bike for it too.

Performance

My experience of the speed and performance of the bike correlate with Trek’s marketing spiel. The bike feels very quick, but that is a subjective experience in some ways. What was more evident was the surety and confidence that the bike gives, it genuinely feels very stable and remarkably comfortable for a TT bike.

You would expect great quality from a top tier bike like the SLR 9, and that is certainly what I saw. All the little finishing touches were nice, and the ability to adjust the cockpit entirely with a unit that still looks streamlined and integrated is very impressive. Shimano Dura Ace 12 speed and the Bontrager 51mm wheels are solid components.

A no-compromise time trial bike, specifically built/marketed towards triathlon but equally as effective for roadies. A great all-around bike that can be dialled in to find the optimal position and gives confidence with its handling and comfort.

Reviews Trek Speed Concept SLR 9 review - Time Trial Triathlon bikes - Bikes

Trek Speed Concept SLR 9 review

The latest iteration of the legendary Speed Concept is here, and Trek says it’s the fastest bike it’s ever tested. Should you splash out? Jack Sexty takes this superbike for a spin…

It’s taken over seven years for Trek to overhaul the Speed Concept, with the finished bike coming after “thousands” of computer-generated iterations and wind tunnel trips to validate what Trek says is “the fastest in its class”.

Trek tells us it experimented with ideas such as beam-shaped frames, but ultimately a more ‘traditional’ double-diamond was more structurally efficient and aero when coupled with the new lowered chainstays. The design also better accommodates new down tube storage and hydration.

It means the redesign doesn’t appear radical, but look closer and you’ll see disc brakes, a new cockpit, integrated top tube storage and the addition of Trek’s IsoSpeed system. The latter is essentially the ‘decoupling’ of the top and seat tubes to add compliance, with Trek extending this further out than on its road bikes to match a triathlete’s more aggressive position. Trek claims the Speed Concept is a huge 30% more compliant, which should leave you less fatigued for the run.

This top-end version costs a huge £12,100, so all mod cons are included, such as a power meter with the SRAM electronic groupset. The ‘cheapest’ Speed Concept with SRAM Rival is £8,100, which still gets you largely the same finishing kit with a slight weight penalty.

On the subject of weight, our size medium test bike is an impressive 8.6kg. Trek says the frameset is lighter than before, with the frame and fork optimised for disc brakes using Trek’s super light 800 Series OCLV carbon.

On a bike this expensive, we were disappointed that base bar shifters weren’t included, which is a useful addition for variable courses. It turned out that ongoing pandemic-related supply chain issues meant that Trek couldn’t source any for our test bike, but future versions will have that option. Speed Concept bikes with Shimano Di2 groupsets are already shipping with base bar shifters.

All About Zwift’s New Trek Speed Concept SLR 9 TT Bike

Zwift’s February update included the 5th frame in game from US-based Trek . Named the “Speed Concept SLR 9”, this is Trek’s first TT frame in Zwift.

Here’s how it is described in Zwift’s Drop Shop:

“Speed Concept SLR 9 is an aerodynamic carbon triathlon bike engineered for incredible speed and seamless integration. Every bit of this bike – from the light aero frame to ride-smoothing IsoSpeed to cutting-edge fuel and hydration systems – has been painstakingly designed to help you beat your PR again, and again, and again.”

This frame is priced at 958,500 Drops, and level-locked at 32. Like all TT bikes currently in game it is rated 4 stars for aero and 1 for weight.

But Zwift’s star ratings aren’t precise enough to communicate actual performance in game in a useful way, and when it comes to time trials, there’s no excuse for not choosing the absolute fastest rig. So we ran the Speed Concept SLR 9 through our battery of speed tests.

Here’s everything you need to know about the performance of the new Trek Speed Concept SLR 9 frame in Zwift.

Aero (Flat/Rolling) Performance

The Speed Concept turns in the 4th-fastest flat test time of any TT bike in Zwift.

Its test time of 49:45.5 is 30.5 seconds faster than the default Zwift TT frame. By comparison, the current fastest TT frame in Zwift ( Canyon Speedmax CF SLX Disc ) turns in a time of 49:41 on our test course, which is two laps of  Tempus Fugit , totaling 34.6km.

Climb Performance

Trek’s Speed Concept SLR9 is described as having a “light aero frame”, but it doesn’t perform like a lightweight bike in our climb test! Its time places it dead last on the list of TT frames in Zwift, with the closest frame 7 seconds ahead.

The Speed Concept SLR 9 turns in an Alpe climb time of 50:42. The fastest TT climber is the Specialized Shiv S-Works at 50:02.

Note: all test results above are from a 75kg, 183cm rider holding 300W steady using Zwift’s stock 32mm carbon wheelset.

Conclusions

While it performs well on flat ground, the Trek Speed Concept SLR 9 isn’t as fast as the Canyon Speedmax CF SLX Disc which is available at a lower level and slightly more affordable. Additionally, its climbing performance is startlingly bad, which makes us wonder if perhaps Zwift has misconfigured the frame.

On the plus side, it has a color slider. But be warned: once you move the slider, you wont be able to find that original red color again.
