How to Change the Travel in a Fox 36

As someone had pointed out, the Yeti SB150 that I presented to a few weeks ago, which I am using for product reviews, was fitted with a Fox 36 fork with “only” 160mm of travel. For this bike Yeti in fact suggests a 170mm fork, so that the so-called vertical travel matches the 150mm of rear travel. The subject was discussed with the engineers of the American brand during the launch of the Yeti SB165 .

I reached out to Fox to ask about taking the 36 Grip2 from 160 to 170mm. Receiving a positive response, I was also told that I could do it myself, and that they would send me the necessary parts kit. ” It’s quite simple, just follow the instructions in the video you’ll find on our site .” And so, I took a look on Ridefox.com and I found everything , even which forks can be modified in their travel and how many volume spacers to insert to have the same feeling as when the fork had 160mm of travel.

The video is very well done and our workshop is equipped with every necessary tool so, after a brief bit of research, I got to work!

You start by removing the fork from the bike and removing all the air from the positive chamber. Then, clamp it in the stand in a horizontal position (so as not to spill the oil when you remove the lowers), then unscrew the rebound knob and the bolts that hold the lower leg assembly in place.

It’s necessary to use a mallet to get the air spring and damper rods to unseat from the lower leg assembly, and there is a special fitting to make the removal easier, which we do not have. I therefore used a small socket bit whose edge is smaller than the threaded part you see below and I tapped with caution.

Next, pour the oil from the lowers into a special container, and then pour it into a bottle that will eventually go to the landfill.

The time has therefore come to dismantle the left side air spring assembly.

To do this I first have to remove the valve cap at the fork crown and REMOVE ALL OF THE AIR from the positive spring. Then, using the appropriate socket, you can remove the valve cap assembly which the volume reducers attach to.

Then I remove the locking ring at the bottom of the stanchion. A thin flat head screwdriver should do the trick.

Now I can take out the piston that I’m going to replace.

Here they are side by side below: the new 170mm one, not yet greased, and the old 160mm one. The difference between the two is only in length. Notice how the well lubricated and clean it is, despite 8 months of use.

Now it’s time to put fresh oil in the lower leg assembly, starting with a small amount placed above the piston. It only needs 3cc. – t he oil, specifically is Fox’s 20WT Gold, which  is very dense.

At this point, I closed the left top cap, removing the volume spacer. In fact Fox suggests starting out with the new 170mm travel without a spacer, as you can see in the table below. I put the air in the chamber: 70 psi, to start, then I’ll do the fine tuning when I put the fork on the bike.

Time to reinstall the lower leg assembly. It’s an o peration that requires a bit of extra patience – to align stanchions with the dust wipers properly, and then push them up.

Again with 20WT Gold oil insert 10cc in the air side (the one I just changed). Instead, on the right side, where the sealed cartridge is, put 40cc of the 5WT oil .

Then tighten the bolts that hold the lowers with a torque wrench to their respective specs (5Nm on the right and 9Nm on the left).

The end! All that remains is to reinstall the fork on the bike and then it’s ready to ride.

In addition to increasing the travel of a 36, ​​it can also be decreased . The operation that I’ve just shown becomes relevant if one decides to change out a frame of a bike, while keeping the components and the situation therefore requires a change in front travel.

The piston kit must be ordered directly from Fox via a dealer.

2020 Fox 36 Fork Review

Both the Fox 36 and Rockshox Lyrik have truly set the benchmark for long travel single crown mountain bike suspension forks . As they continue to evolve, Fox and Rockshox are both working towards the magic combination of ultimate trail performance and reliability. For this review, we are taking a look at the 2020 Fox 36 fork . With an updated FIT4 damper and an award winning FIT GRIP2 damper, the Fox 36 is one of the most versatile forks on the market. You will find the 36 on the top of the podium in both Crankworx Slopestyle with Brett Rheader and the Enduro World Series with Martin Maes. We know the 36 is impressive, but we want to know how impressive. Here we go!

Fox 36 Fork Specifications

The 36 fork is a staple in Fox's lineup of mountain bike suspension. You will find the 36 on everything from dirt jump bikes, your weekend warriors' every day trail bike, to race winning enduro world series bikes. The 36, just like it sounds, uses 36mm upper tubes for a stiff and rigid chassis. This fork is now offered in a variety of different configurations at different price points. The FIT GRIP2 damper is a 4 way adjustable sealed cartridge damper with Fox's new Variable Valve Control. Check out our full review of the GRIP2 damper ! The alternative FIT4 damper gets an overall for 2020 that is aimed to improve sensitivity while maintaining mid stroke support. 

The 36 is still offered in either 100mm wide or 110mm Boost axle configurations. With different travel options ranging from 150 to 180mm for both the 27.5 and 29 chassis, the Fox 36 is one of the most versatile forks on the market. Below you'll find more technical information on the Fox 36.

The Bike Setup

For this particular review, we are riding the 2020 Fox 36 fork with the Grip2 damper, 160mm of travel, 15x110mm Boost axle, and 44mm offset . The fork is mounted up to an all new Santa Cruz Hightower with 140mm or rear wheel travel. The bike is outfitted with Industry Nine Enduro 305 wheels with Maxxis DHR II EXO+ casing tires . Finished off with Sram Eagle XX1 AXS drivetrain and the new Deity Skywire carbon handlebars , this bike is ready for it all. 

Riding and Performance

In 2019, Fox introduced the all new 4 way adjustable Grip 2 damper. The new damper design uses Fox's Variable Valve Control (VVC), a new way to control the high speed rebound damping by changing valve stiffness instead of adding preload to a shim stack. So what does that mean out on the trail? The fork's job is actually more about keeping your tire in contact with the ground giving you grip. Your arms and legs are there to absorb those big impacts. The Grip 2 damper seen in both the Fox 36 and Fox 40 is effectively more sensitive all without riding lower in the travel. Riding the 36 on the new Hightower, the Grip 2 damper allows you to ride the bike in the sweet spot of the travel without sacrificing grip or suspension sensitivity. That can be a tough balance to find sometimes and the latest Fox 36 makes tuning and setup easy.

One aspect of performance that is important to consider is the chassis. The 36 is definitely on the stiffer side of the spectrum compared to other options out there. Compared to the Rockshox Lyrik, when you point the front end where you want to go, the Fox 36 will take you there. The drawback to that is, the chassis is stiff enough that if you get yourself in tough spot out on the trail, the 36 might have your front wheel pinging off rocks and roots. There is a balance between stiffness/responsiveness and compliance/comfort and this is one aspect of performance that separates the Fox 36 from its competitors. 

What's The Bottom Line?

The Fox 36 is a top of the line contender for the most capable mid to long travel suspension fork on the market. The damping performance with the Grip 2 damper is a major improvement from its predecessor, keeping your tire in contact with the ground, and the 36 chassis allows you to be direct, precise, and assertive out on the trail. One thing different about the Fox 36 compared to other forks out there like the Rockshox Lyrik is that the chassis isn't as much designed for pure comfort as it is the aggressive rider. The Fox 36 is meant to be ridden hard and that's where it shines.

Fork travel changes can be confusing. While we won’t go into depth on ride characteristics associated with increasing or decreasing travel here, head tube angle, bottom bracket height, etc., we do want to outline some compatibility issues you may run into when bumping up fork travel.

Travel Change Chart For Common Fox And Rockshoxs Forks

Fox 36 info

• 2018 fox 36 29er forks can be bumped up to 170mm it will require various parts to make it happen though new parts needed are: new CSU, Lowers, and damper. It is usually cheaper to just buy a new fork.
• 2019 fox 36 29er forks can go to 170mm with no modification needed.
• To identify which fork you have all you need to do is look at your damper. RC2 dampers are 2018 and older. 2019 forks will have The grip 2 damper

Fox 34 info

• While 2016 29in 34mm forks may have travel extended up to 140mm, forks starting at 120mm or below will need a new damper to achieve greater than 120mm travel

The New Fox 36 Makes It Even Easier to Send It Without Losing Control

New tech makes this one of the best feeling and most adjustable long-travel forks we've tested

Price: $1,065 (as tested) Weight: 4.6 lb. (160mm, 29-inch version) Use: Trail, enduro

Ever since its introduction in 2005, the Fox 36 has been a class-leading fork for riders who want a burly chassis without a massive weight penalty. Over the past few years, Fox has made incremental changes to the platform, updating the damper to improve the ride and most recently adding the Float EVOL air spring. Those tweaks have kept the 36 at the top of the wishlist for enduro and aggressive trail riders. For 2019 Fox is giving the fork an all new FIT GRIP2 damper, which has more adjustability and even better performance on the trail. (Fox will continue to offer a version with the older FIT4 damper.) And for riders who use every millimeter of travel, there’s more good news. The new 36 gets a travel increase up to 170mm for 29-inch wheels and 180mm for 27.5-inch wheels.

Versions for All the Wheel Sizes The new 36 with GRIP2 damper doesn’t care what size wheels you run. It comes in versions that fit 29, 27.5, and 26-inch hoops (the GRIP2 damper will also be used in Fox’s dual-crown 40 downhill fork). Fox also makes two versions with the GRIP2 damper. The top-of-the-line Factory fork comes with the extra-slippery Kashima-coated stanchions and costs $1,065. The slightly less expensive ($973) Performance Elite option has black anodized stanchions. The new 36 also has several offset options: For 27.5-inch wheels there are 37 or 44 millimeter versions; offsets for 29-inch wheels are 44 or 51 millimeters. Fox is moving away from its original blue and gray graphic packages and this new fork comes in two color options: black and gloss orange.

Getting a Handle on the GRIP2 Damper The big story here is the new FIT GRIP2 cartridge, which features an entirely new design with four-way external adjustment: high- and low-speed compression damping, and high- and low-speed rebound damping.

Things get really interesting when you look at the rebound side of the damper. The high-speed circuit employs a new patent-pending Variable Valve Control (VCC) design. This valve is essentially a leaf spring, and the external adjuster changes the bending point of the spring. According to Fox, adjusting this valve creates an effect similar to a complete revalve of the shim stack (a pro-level mod that requires tearing apart the fork)–when you turn the adjuster, the damping changes progressively, and the damping force is consistent from the beginning to the end of the stroke. Most riders will feel an improvement over the old design, which produces more initial damping force (to slow the fork’s return rate) but then a gradual increase in speed which creates a sort of a trap-door effect that feels less consistent as the fork returns to its original position.

On the compression side, the GRIP2’s basic architecture is similar to the previous version: a shimmed piston (a very common damper design: it’s used in Fox’s Float shocks and other products). However, Fox engineers reduced shaft and seal friction to improve overall smoothness and small-bump performance. The new damper also gets a larger piston and more oil volume, which improves consistency, especially on more demanding terrains where the fork is getting hammered. The new version also gets a cool little mid-valve—a secondary damper that allows engineers to really fine tune fork performance in certain situations.

Finally, users will find a wider range of compression adjustments. That is especially valuable for lighter and heavier riders, who often reported that a fork’s performance declined at the far reaches of its compression-adjustment limits.

A New Floating Piston Keeps Thing Slippery and Consistent The FIT GRIP2 uses a spring-backed internal floating piston, also known as an IFP, as a volume compensator. To understand its value, a quick intro to damper design helps: When you hit a bump, the fork’s damper rod moves into the fork chassis, which is filled with oil to slow the compression. The rod’s movement displaces oil, which needs someplace to go. In the GRIP2, that oil pushes against an IFP, which slows the oil movement for better control, and also prevents air from rushing into the damper to fill the void—fork’s begin to fade if too many air bubbles mix with the oil.

The previous RC2 used a tightly sealed expanding bladder as a volume compensator, and two different fluids inside the fork leg: one for the damper, and one for the fork’s internal lubrication. But the lubricating fluid could get sucked into the damper over time, altering the makeup of the damping fluid and changing the fork’s performance. With the GRIP2’s IFP design, Fox uses the same fluid for lubrication and damping and designed the fork to recirculate small amounts of fluid from the damper to the lubrication system. You get a more consistent fork movement that requires less regular maintenance.

Another clever detail: A small teardrop-shaped dimple on the IFP shaft purges excess fluid when the fork reaches the end of its stroke. That prevents the damper from overfilling, which can stop the fork compression before it hits full travel, which you absolutely don’t want when slamming into a rock or landing nose-heavy off a drop. This design allows Fox to use a looser fitting main shaft seal, which further reduces friction so the fork feels more supple on the trail.

Our Ride Impressions In back-to-back comparisons with a 2018 FOX 36 RC2, the new 36 with a FIT GRIP2 damper was noticeably superior, especially on rocky trails with hard, G-out hits. It felt more composed, plusher, and the front end of the bike was more predictable because of it.

Overall, the new damper seems to offer a quieter ride with less feedback, which leads to better traction. Test riders also noticed that increasing compression damping seemed to add support, but without increasing harshness, which can happen on some other forks. This allows you to tune in the type of ride you prefer–from plush and comfortable to something more supportive —without sacrificing much sensitivity.

For some riders, navigating high- and low-speed rebound adjustments can be a pain because it makes the fork more challenging to set up properly. (Fox does provide recommended base tunes, which, according our testing, are a good starting point). But the benefit comes from the expanded range of rider-adjustable fine tuning. For riders who are willing to put in the work (riding the same section of trail over and over again while making small adjustments) this should result in a better overall ride. This is especially valuable to riders at the higher and lower ends of the weight curve and anyone who likes to tinker with their setup to get their ideal performance.

• Fox 36 Rhythm travel

My Fox 36 Rhythm forks are supposed to have 150mm travel. The exposed stanchion does indeed measure 150mm, but even with the air out, the fork stops at about 137mm. it stops with a clunk, so there is definitely some sort of mechanical stop. Has anyone else noted this on these forks?

I have similar behaviour on my 150mm performance elite ones with the FIT damper (I think I measured travel at 140mm, with a smidge over 150mm of sanction showing). I suspect it might be a case of having too much oil in the lower legs but haven’t bothered stripping them down for a service yet to see if that solves the problem.

Also, probably won’t help fix this but have you tried getting and pressurised air out of the lowers by sticking something like the pointy end of a plastic cable tie in the fork seal? When I first out mine in they had quite a build up in the lower legs that was making them very progressive later in their travel, even with the main air chamber next to empty.

Please enable JavaScript

Thanks, I’ll try both those. However, there appears to be a solid ‘stop’ at 137mm, as though that is the limit of the travel.

The only other thing I can think of where it could be possible to have something stopping full travel (other than excessive tolerance on the air shaft length) would be having too much grease in the negative air chamber. Having said that I would expect this to limit the full extension of the fork so it is far less likely to be responsible for what we are seeing given the length of sanction on show when unloaded.

I’m reaching for my coat – it appears that the fork crown is hitting the mudguard (Mudhugger)! I really should have spotted that …… @bigginge – there was air in the lowers, though.

Max ad-free streaming service is getting a price hike

Warner bros. discovery is raising prices for its ad-free max subscription offerings.

Disney, Warner Bros. streaming services bundle defeating its own purpose: Bobby Iaccino

Bobby Iaccino, co-founder of Path Trading Partners, weighs in on the effectiveness of bundling streaming platforms and why he believes the move defeats its own purpose.

Warner Bros. Discovery on Tuesday raised the price for the ad-free subscription to its Max streaming service .

The move, which will take effect immediately for new subscribers, hikes the monthly ad-free plan's price by $1 to $16.99 a month. It will also increase the annual ad-free plan price by $20 to an annual cost of $169.99.

Prices for Max's ultimate ad-free tier, which includes features such as the ability to have four streams running at the same time and 4K streaming options, will increase by $1 to $20.99 a month.

Current monthly subscribers will receive a notice informing them about the price changes 30 days before their plan renews, with changes reflected after their July billing cycle, while users with annual subscriptions won't see a change until their renewal date.

The price for the Max plan that includes ads remains unchanged at $9.99 per month.

Warner Bros. Discovery's move comes as a range of streaming platforms have moved to raise prices and bundle their offerings with those from other services.

Last month, Warner Bros. Discovery and Disney Entertainment announced a new bundle that would include Max with Disney+ and Hulu.

The bundle will include package options that are ad-supported and ad-free and will be available on any of the three streaming platforms' websites. The companies said additional details about the new bundle, including its cost, will be shared in the coming months.

Similarly, Comcast announced in late May that its new "StreamSaver" bundle will feature Peacock Premium, Apple TV+ and a standard Netflix subscription with ads.

The bundle, which became available May 29, costs $15 a month and aims to simplify streaming subscriptions for consumers while saving them money.

Day trip to Suzdal from Moscow: transport, sights, maps and tips

 DAY TRIP TO SUZDAL

  Suzdal is one of the most popular destinations on the Golden Ring and the whole city is often described as an open-air museum.  The city has no railway station and practically no heavy industry, meaning that is has preserved its provincial charm and a great deal of architectural monuments.

  From Moscow, Suzdal is not as easy to get to as Sergiev Posad (the closest Golden Ring city to the capital) but it is worth going the extra distance as Suzdal provides more of a contrast from Moscow.  If you make use of high-speed trains it is possible and not too demanding to visit for even just a day, but of course spending the night there is recommended to soak in the atmosphere or to combine it with a visit to neighbouring Vladimir.  As the city is a very popular tourist destination you will have no problem finding a cafe or guesthouse there.  There is practically no public transport in the city, but the city is small and most sights are located relatively close to each other.

Getting There and Back

Via Vladimir

Direct to Suzdal

  Buses directly to Suzdal leave from Moscow’s Schyolkovsky Bus Station.  There are about 9 buses a day and it takes around 4½ hours depending on traffic.  The buses stop at Vladimir too.  Using this option will mean a rather exhausting day trip.

Orientation and Main Sights

  Suzdal is a relatively small city and it is not difficult to walk around the city to see most of the sights.  

  The main road in the city is Ulitsa Lenina which runs north across the whole city.  

  The main sights of Suzdal are located either on or just off this road, including the two main sights: the Suzdal Kremlin in the south and the Spaso-Yevfimiev Monastery in the north.

  More information about Suzdal can be found on our Suzdal  pages.

  Suzdal is famous for its medovukha (mead) which is an alcoholic drink made out of honey.  It can be drunk either hot or cold, meaning it perfect in both summer and winter, and you will find it on practically every menu in the city.  There are various flavours of the drink available and even a non-alcoholic version.  In addition to medovukha, you can find all traditional Russian souvenirs in the city and there is a big souvenir market on Torgovaya Ploschad.

• Test the proper operation of your front and rear brakes on level ground.
• Before every race or ride, clean the outside of your fork with only mild soap and water, and wipe dry with a soft dry rag. Do not spray water directly into the seal/upper tube junction.  Do not use a high pressure washer on your fork.

WARNING:   Follow your brake manufacturer's installation instructions for proper installation and adjustment of the brake system. Failure to properly install and adjust your brakes can lead to a loss of control of the bicycle which can result in SERIOUS INJURY OR DEATH.

The 2015-2019 36 FLOAT uses 180mm Post Mounts that allow you to bolt your caliper directly to the fork and utilize a 180mm rotor. This post mount eliminates the need for a caliper adaptor when using the most common 180mm rotor size for forks with these amounts of travel, which saves overall system weight. 

If your current 180mm brake setup came with bolts and a caliper spacer, you may need to source shorter bolts as you will not need a caliper spacer when using a 180mm rotor.

If using a 203mm rotor, you will need to source the appropriate caliper spacer and bolts. Contact the brake manufacturer for further information.

Install Your Wheel Correctly to Benefit From the Floating Axle

Some 2015-2019 36 forks use a true floating axle. Follow the installation instructions in the video below to properly install your front wheel and enjoy the friction reducing benefits of the floating axle. 

Wheel installation is identical for both the 15mm and 20mm axles. Information regarding converting between 15mm and 20mm axles can be found in the 15mm and 20mm Axle Conversion  section. Additional information regarding installing wheels can be found  here »

2019 36 FLOAT maximum air pressure is 120psi (8.3 bar)

NOTE: Pressure measured at an ambient temperature of 70-75ËšF. Normal operating temperature range for FOX products is 20-140ËšF.

Depending on variables such as riding style, terrain, bike geometry, etc, you may find that you can only achieve proper sag and ride performance with up to 10psi over or under the recommended value in the suggested starting pressure chart below. Feel free to experiment with fork air pressures using the information below as a guide.

Setting sag is desired and necessary for proper fork performance during general XC/Trail/AM riding. The 831 fork is not intended for general XC/Trail riding use, but for four cross racing, slalom, slope-style, or dirt jumping. Therefore, the air pressure is generally not set by obtaining proper sag, but is intended to be set for proper riding feel and bottom out control. 

Sag should be set to 15 - 20% of total fork travel

To achieve the best performance from your FOX suspension, adjust the air pressure to attain your proper sag setting. Sag is the amount your suspension compresses under your weight and riding gear. Sag range should be set to 15–20% of total fork travel.

• Attach a FOX High Pressure Pump to the Schrader valve.
• Pump your fork to the appropriate pressure as listed in the 'Suggested starting points for setting sag' table below, then remove the pump.
• Using your forks sag setting o-ring on the left upper tube (or temporarily install a zip tie to the upper tube), slide the o-ring (or zip tie) down against the fork dust wiper.
• Rotate the compression lever to the Open mode (fully counter-clockwise).
• If you have a 3-Position Remote fork, set the fork to Open mode.
• If you have LSC or HSC/LSC adjust, make sure all adjusters are open (fully counter-clockwise.
• Dressed to ride (including a filled hydration pack, if you use one), position your bike next to a wall or table to support yourself. Mount your bicycle. Assume your riding position for at least 10 seconds, allowing the suspension to fully settle. Make sure you distribute your weight evenly between the saddle, handlebars and pedals.
• While in your riding position, slide the o-ring (or zip tie) down against the fork dust wiper.
• Dismount your bike without bouncing, to avoid further moving the o-ring or zip tie. Measure the distance between the dust wiper and the o-ring or zip tie. This is your sag measurement. Suggested sag measurements are listed in the table below.
• Add or remove air pressure until your sag measurement is between 15-20% of your forks total travel.
• Repeat steps 2-8 and recheck sag measurement.
• When sag measurement is correct, screw the air cap on clockwise until snug.

Rebound controls how fast the fork extends after compressing

The rebound adjustment is dependent on the air pressure setting. For example, higher air pressures require more rebound damping.

Use your air pressure to find your rebound setting. Turn your rebound knob to the closed position (full clockwise) until it stops. Then back it out (counter-clockwise) to the number of clicks shown in the table below.

Adjust rebound until when tested, the fork returns quickly but does not top out.

Top out is felt when a fork fully extends too quickly and comes to an abrupt stop when it reaches full extension (you will hear/feel a small noise). Top out should be avoided through proper rebound setting.

Easy on-the-fly adjustments for unprecedented control and performance

3-Position Lever : The 3-position lever is useful to make on-the-fly adjustments to control shock performance under significant changes in terrain, and is intended to be adjusted throughout the ride. You can use the OPEN mode during rough descending, the MEDIUM mode for undulating terrain, and the FIRM mode for smooth climbing.

FOX recommends beginning with the 3-position lever in the open mode.

*OPEN Mode Adjust : Open mode adjust is useful to control fork performance under rider weight shifts, G-outs, and slow inputs. OPEN mode adjust provides 22 additional fine tuning adjustments for the OPEN mode. Setting 22 will have a more plush feel and setting 1 will have a firmer feel.

FOX recommends beginning with the Open mode adjust set to 18 clicks out (counter-clockwise) from fully closed (clockwise).

*Factory and Performance Elite Series forks only.

Independently Control High and Low Speed Compression

Adjusting your high and low speed compression setting controls how the fork feels as it's compressed through its travel under various types of hits. Use your high and low speed compression adjusters to tune the fork to meet your riding style and terrain.

High-speed compression (HSC)  adjustment is useful to control fork performance during bigger hits, landings, and square-edged bumps.

Low-speed compression adjustment is useful to control fork performance during rider weight shifts, G-outs, and other slow inputs.

FOX recommends turning adjusters fully clockwise until they come to a  gentle stop  (approximately 2 in-lb/ 0.2 Nm torque) then turning counter-clockwise to the recommended setting. Any High-Speed Compression settings beyond 16 clicks out from fully closed do not change damping. While the HSC adjuster may have more than 16 detent clicks, only the 16 positions closest to fully closed are designed for use. Any clicks beyond 16 out from fully closed are due to the configuration of the adjuster and will not affect performance in any way.

FOX recommends beginning with the  High-speed compression set 10 clicks out  (counter-clockwise) and  Low-speed compression set 6  clicks out  (counter-clockwise) from closed (full clockwise). 

Adjusting your  low-speed compression setting controls how the fork feels as it's compressed through its travel under various types of hits. Use your low speed compression adjusters to tune the fork to meet your riding style and terrain.

Low-speed compression (LSC)  adjustment is useful to control fork performance during rider weight shifts, G-outs, and other slow inputs.

3-Position Micro Adjust:  The 3-position lever is useful to make on-the-fly adjustments to control fork performance under significant changes in terrain, and is intended to be adjusted throughout the ride. Turning the lever to the full counter-clockwise position sets the fork in the Open mode. Turning the lever to the middle detent position sets the fork in the Medium mode. Turning the lever to the full clockwise position sets the fork in Firm mode. The positions between the Open, Medium, and Firm modes can be utilized to fine tune your compression damping. 

FOX recommends beginning with the 3-position lever in the Open mode.

The 2-Position remote can either be installed under the handlebar on the non-drive side, where a front shifter would typically be placed, or installed above the handlebar on the drive side. The 2-Position remote can be used with two cables to control both Push-to-Unlock forks and shocks simultaneously. The 3-Position remote can be installed in-line with the handlebar on either side and can control the fork or shock.

FIT4 DAMPERS (Push-to-Lock and Push-to-Unlock)

• Install the remote lever onto your handlebar. Do not exceed 1.7 Nm (15 in-lb). Less torque may be needed for carbon bars. Refer to the handlebar manufacturer’s instructions for use with carbon bars. Make sure to check for clearance between the remote lever and any brake or shifter controls.
• For Push-to-Lock forks only  - route the cable housing from the remote lever, around the rear of the crown, to the fork topcap cable stop and cut to length. Install a ferrule on the remote end.
• For Push-to-Unlock forks only  – route the cable housing from the remote lever, across the front of the crown, to the fork topcap cable stop and cut to length. Install ferrules on both ends.
• Set the remote lever to OPEN mode by pushing the release lever. Make sure that the cable head is completely seated in the remote lever.
• For 2-Position remotes only  - use a short piece of housing with one ferrule between the in-line barrel adjuster and the remote lever body.
• With all cable housing fully seated and no slack in the system, lightly lubricate the inner cable and thread it through the cable housing and around the fork remote pulley.
• While holding the cable tight, tighten the pinch bolt, cut off excess cable, and crimp the end.

GRIP DAMPERS (Push-to-Lock only)

• Route the cable housing from the fork topcap, around the rear of the crown, to the remote lever and cut to length. Install a ferrule on the end of the housing at the remote lever. The end of the housing at the fork topcap does not require a ferrule.
• Set the remote lever to FIRM mode by pushing the actuation lever. Make sure that the cable head is completely seated in the remote lever.
• Use a 5 mm hex wrench to turn the remote pulley clockwise until you feel it lightly stop, then hold it in place.  For forks with the cable exiting the topcap at the rider’s 1 o’clock position:  the remote pulley should stop at the 10-11 o’clock position.  For forks with the cable exiting the topcap at the rider’s 7 o’clock position: the remote pulley should stop at the 4-5 o’clock position.
• With all cable housing fully seated and no slack in the system, lightly lubricate the inner cable and thread it through the cable housing and around the fork remote pulley. While gently holding the remote pulley against the clockwise stop with your 5 mm hex wrench, tighten the pinch bolt.
• Release the 5 mm hex wrench from the remote pulley, cut off the excess inner cable, and crimp the end.
• The in-line barrel adjuster may be used to change the lockout blow-off force. Clockwise barrel adjustment increases blow-off force, while counter-clockwise adjustment decreases blow-off force.

The 2-position remote is designed to be used in place of a front shifter, under the handlebar on the rider's left side. The 2-position remote can be used with 2 cables to control both the front fork and rear shock simultaneously.

The 2-Position Remote lets you to switch between the OPEN and FIRM modes while riding.

• Push-to-Lock  – Push the actuation lever to set the fork to FIRM mode. Push the release lever to set the fork to OPEN mode.
• Push-to-Unlock  – Push the actuation lever to set the fork to OPEN mode. Push the release lever to set the fork to FIRM mode.

Adjust Your Compression Ratio For The Perfect Air Spring Feel

Changing volume spacers in the 36 FLOAT fork is an easy internal adjustment that allows you to change the amount of mid stroke and bottom out resistance.

If you have set your sag correctly and are using full travel (bottoming out) too easily, then you could install one or more spacers to increase bottom out resistance.

If you have set your sag correctly and are not using full travel, then you could remove one or more spacers to decrease bottom out resistance.

*DO NOT EXCEED THE MAXIMUM NUMBER OF VOLUME SPACERS LISTED ABOVE!    

36mm FLOAT volume spacer PN: 234-04-736 is orange and has a volume of 10cc

36 Rhythm volume spacer PN: 234-44-079 is purple and has a volume of 10cc

A look at the US' 'duty to warn' and how it came into play ahead of the Moscow attack

Russia has also warned the us of threats in the past, including the man who would become the boston marathon bomber.

Russian authorities charge four men in concert hall massacre

Fox News senior foreign affairs correspondent Greg Palkot reports from London on Russia's investigation into a terror attack at Crocus City Hall on 'Your World.'

The U.S. warning to Russia couldn't have been plainer: Two weeks before the deadliest attack in Russia in years, Americans had publicly and privately advised President Vladimir Putin's government that "extremists" had "imminent plans" for just such slaughter.

The United States shared those advance intelligence indications under a tenet of the U.S. intelligence community called the "duty to warn," which obliges U.S. intelligence officials to lean toward sharing knowledge of a dire threat if conditions allow. That holds whether the targets are allies, adversaries or somewhere in between.

There's little sign Russia acted to try to head off Friday's attack at a concert hall on Moscow's edge, which killed more than 130 people. The Islamic State's affiliate in Afghanistan claimed responsibility, and the U.S. said it has information backing up the extremist group's claim.

ISIS USING DEADLY MOSCOW ATTACK TO RECRUIT NEW TERRORISTS AS US MONITORING 'VERY CLOSELY'

John Kirby, the Biden administration's national security spokesman, made clear that the warning shouldn't be seen as a breakthrough in U.S.-Russian relations or intelligence-sharing. "Yeah, look, there's not going to be security assistance with Russia and the United States," Kirby told reporters Monday.

"We had a duty to warn them of information that we had, clearly that they didn't have. We did that," Kirby said.

Such warnings aren't always heeded — the United States has dropped the ball in the past on at least one Russian warning of extremist threats in the United States.

Here's a look at the duty to warn, how it came about, and how it can play out when American intelligence officers learn militants are poised to strike.

AHEAD OF THE ATTACK, A CLEAR US WARNING

On March 7, the U.S. government went public with a remarkably precise warning: The U.S. Embassy in Moscow was monitoring unspecified reports that "extremists have imminent plans to target large gatherings in Moscow, to include concerts." It warned U.S. citizens in Moscow to avoid big events over the next 48 hours.

U.S. officials said after the attack that they had shared the warning with Russian officials as well, under the duty to warn, but gave no details how.

Putin's public reaction was dismissive. Three days before the attack, he condemned what he called "provocative statements" from the West about possible attacks within Russia . Such warnings were aimed at intimidating Russians and destabilizing the country, he said.

DUTY TO WARN

The U.S. emphasis on sharing threat warnings increased after al-Qaeda's Aug. 7, 1998, attacks on the U.S. embassies in Kenya and Tanzania. While dozens of U.S. citizens and government employees of different nationalities were killed, Kenyans made up the majority of the victims.

In 2015, then national intelligence director James Clapper formalized duty to warn in an official directive: The U.S. intelligence community bore "a responsibility to warn U.S. and non-U.S. persons of impending threats of intentional killing, serious bodily injury or kidnapping."

The order also spelled out occasions when intelligence officials could waive the duty to warn and stay silent despite looming danger. That includes when the target is an assassin or other extreme bad guy, or when disclosing the warning could "unduly endanger" U.S. personnel or their sources, those of intelligence partners among foreign governments, or their intelligence or defense operations.

SHARED WARNINGS AND THE BIDEN ADMINISTRATION

The intelligence community under former President Donald Trump faced accusations it had failed to warn U.S.-based journalist Jamal Khashoggi of a complex plot by Saudi officials that ended with his 2018 killing inside the Saudi consulate in Istanbul. Media foundations say U.S. intelligence agencies did not respond to requests for any records showing whether they knew of the plot in advance.

Under the Biden administration, the sharing of threats to other governments has flourished, although there's no way to know of any threats that the U.S. intelligence community may have decided to let play out, without warning the targets.

Strategic U.S. dissemination of intelligence hit a high point in the months before Russia's February 2022 invasion of Ukraine. That's when the U.S. opted to declassify key intelligence on Russia's invasion plans to rally allies and Ukraine, and — unsuccessfully — to pressure Russia to call off its troops.

In a Foreign Affairs article this spring, CIA Director William Burns spoke of a growing awareness of the value of "intelligence diplomacy" — the strategic use of intelligence findings to bolster allies and confound adversaries.

SHARING ISN'T ALWAYS CARING

The duty to warn doesn't mean the other side has a duty to listen. That's especially so when the other side is an adversary.

In January, a U.S. official said, Americans had given a similar warning to Iranian officials ahead of bombings in the Iranian city of Kerman. The Islamic State claimed responsibility for that attack, twin suicide bombings that killed 95 people.

It's not clear if the warning led to any additional security precautions at the event, a commemoration of the 2020 killing of an Iranian general by a U.S. drone strike.

In 2004, another adversary, the government of Venezuelan President Hugo Chávez, an anti-U.S. populist, was "suspicious and incredulous" when U.S. officials relayed a warning of an extremist plot to kill him, Stephen McFarland, a former U.S. diplomat in Central and South America, said Monday on X.

That kind of deep distrust has often kept threat warnings from landing as intended when it comes to Russia and the United States. That's true even with common dangers that both face, including the Islamic State and al-Qaida.

Historically, Russians can regard any U.S. attempt at counterintelligence cooperation against that kind of shared threat as naive, and look for any openings to use it for political gain or to undermine U.S. intelligence-gathering, Steven Hall, a longtime U.S. intelligence official in the former Soviet Union, wrote after his retirement in 2015.

In 2013, it was U.S. officials who, tragically, failed adequately to follow up on a Russian warning, a U.S. government review concluded later.

Concerned the man posed a threat to Russia as well, Russia's Federal Security Service in 2011 warned U.S. officials that a U.S. resident, Tamerlan Tsarnaev, was an adherent of extremist groups. After U.S. officials concluded Tsarnaev was not a threat in the U.S., he and his younger brother planted bombs along the route of the Boston Marathon, killing three people and injuring hundreds.

Fox 36 fork: Is there such a thing as an "adjusted max psi"?

• Add to quote

I have a Fox 36 Float, 110-160mm internally adjustable travel fork. Here is the 2015 Fox 36 link. The fork is adjustable in 10mm increments and currently set to 130mm travel. Fox states the max psi for this fork is 125psi, but no mention at which travel setup. I would assume the stated max value applies to the longest travel setting: 160mm because it would have the highest peak psi at full compression - let's just say 300psi in this case. It stands to reason that Fox would be most concerned with not blowing past this peak compression psi, but they only state the single max value and not for each of the other settings. So for the shorter travel setups which would achieve a lower peak psi value at full compression, my assumption is that the max psi value should be adjusted for each of these travel points. Take the shortest travel setting of 110mm and you have reduced the mechanical compression by 50mm, so the peak compression psi in this case might (another swag, only 200 psi). Is this making sense, and if so, what would the adjusted max psi be for 130mm travel - the mid point between 110 & 160mm (or perhaps a chart or equation to calculate the correct adjusted values)? I am not sure if this concept has been previously discussed. I did not find it posted, so my apologies if it has. Please post relevant references if available. Thank you.  

The recommended pressures have a pretty huge margin for safety so you can definitely run more than that but do you need to? It’s pretty rare to find a case where you need much more than that, generally riders needed higher pressure want longer travel too There’s a few air spring calculators around nowadays that will calculate the pressures, or if you know the length of the chamber it’s pretty easy to work out  

Mechanical compression is reduced on a shorter travel fork but often the volume of the air chamber is reduced as well. A fork with less travel and less air volume can build more pressure through the stroke than a longer travel higher volume fork. Factory setups usually install more volume spacers into a shorter travel fork than a longer travel one. Some one could in theory make an adjusted max air pressure chart but it would need to factor in total number of volume spacers as well.  

We are running this particular fork on a mtb tandem, so yes, something of a rare case. As a team we are sub 300lbs, but still over the weight chart which stops at 250lbs. When we had the travel set to 120mm, I was running 128-130psi with 2 orange vol spacers. Now running 130mm and 1 orange spacer. On the weight side, a lot of teams much heavier than us also use this fork, but most of our rides will find us on rougher terrain, step downs, smaller jumps, etc. When we're pointing the tandem straight down a steep rocky pitch and drop over something, almost all of our weight is on the fork and either at or near the max travel (ie: bottomed out). I am trying to figure out the best option for a firmer initial and mid stroke, not waiting until the last of the travel to ramp up. So right now with a little more travel and 1 less vol spacer, that will allow more air vol (larger chamber) and I'm hoping more "base" platform. Tandems tend to plow through stuff, so initial suppleness isn't a primary goal for us.
