Has anyone seen any Rockshox athletes running flight attendant on their bikes? I haven’t been able to spot any from my casual peruse of the footage from the first 2 EDRs. 

I remember Charlie Murray (NZ) was running flight attendant last year after it got released but don’t know for how long that lasted

Yeh that’s right. I’ve been seeing over the summer (our southern summer) that he hasn’t had it on and obviously not on any other athletes it seems this season. Just curious as it seemed targeted as a racing product but the top racers don’t seem to be running it. 

I could be wrong since things change so fast, but Flight Attendant is still based on the bladder charger 2.1 damper, and hasn't been upgraded to the charger 3 yet. This likely explains why none of the pros are using it anymore.

The Fox GRIP2 damper looks 5 years old, but it got a pretty important update that flew under the radar when they did the VVC adjuster inside the damper 3 years ago. Unfortunately, the knobs on the outside look the same so you can't tell it's different, but it's a pretty clever invention that allows them to fine tune their high speed rebound and compression shims in place on the damper rod without preloading them. The original GRIP2 damper (and lots of other fork dampers in lots of other brands) use the high speed knobs (on compression or rebound) to adjust preload on shims. This achieves the goal of increasing damping force through those shims but it doesn't do so evenly across the speed range, creating a digressive damper tune for heavier riders. Digressive means lots of damping force until you overcome the preload, then it blows wide open. Not ideal, but a pretty common way to deliver adjustable high speed damping for customers that doesn't require taking apart the damper and installing rider-specific shim stacks.

The VVC damper doesn't preload the shims, it actually changes their spring rate via a knob, which allows heavier riders to run more high speed damping AND have it more consistent across various shaft speeds. Think of preloading a coil spring versus changing coil springs- one is much more effective at tuning spring rate than the other. I haven't ridden one, but I love the thinking, and I don't know of another damper that can do what the VVC adjusters do. If you're curious, there's a pretty good video from Fox explaining how they work: https://www.youtube.com/watch?v=krLP9cawQAA

Well the VVC wasn't that much of an upgrade since it made highspeed compresseion almost irelevant anyway. 

I do agree tough, the old Grip2 HC was more compression than I needed. This is what a usefull range of settings is for, isnt it? But the new one felt like some twiddly knobs you find at any walmart fork just to look cool.

anybody have any new insights about the release date of the new boxxer / vivid?

on the subject of release dates, shouldn't the embargo on the new Spez ended by now?, what happened, did they postpone the launch date?

Weird, Did Devinci forget about 6ft riders, less than 470 reach and close to 500 is too much...

current trend is brands relaxing those reach numbers... devinci didnt get the memo i see.

The latest photos of the unreleased sram caliper, the black one that looks a bit like the original Code caliper. It seems to look quite different from the previous prototype that was red with paint splat effect over it. The shapes around the pistons are different, the latest black one is flatter and the red one had some unusual looking shapes on it. The piston area had bulges in the middle that the latest black one doesn't have.

I'm guessing the current Code is staying and this will be released as a dh specific brake, but it's interesting that theres been no spy shots of any completely new lever designs to go with this new caliper.

I know the new code lever is different but its only changed to be closer to the bars, apparently the internals have not changed.

Does anyone know if the red one is still being spotted being tested out in the wild by pros? Anyone have any ideas on what the bulges on the red one were all about?

I'm hoping the eventual production version looks more like the red one but it seems the black one has a model name which suggests thats the version they are going with?

"The reach numbers should give riders plenty of room on the bike. They start at 449mm on the size S and climb to 469mm, 494mm and 519mm for the M, L and XL bikes.

Looked sick. They'll help fund to the work of the foundation. Its basically an alloy, park oriented Spartan (similar spirit to the Commencal Furious). Can't remember pricing.

Anyone have leads on products releasing at Sea Otter next week? Hope to see a few surprises.

You’re a beautiful person and you should know this! 😃

Strangely, this Devinci looks exactly like my next bike! 😂 Can anyone extrapolate on how Devinci managed to get another 10mm of travel? By a longer shock, by a different link, a combination?

Hey Jerry, 

Seems like its the black version thats going forward then... you wouldn't happen to have noticed if any of them were running a new brake lever? Whistling

Ever since the Trickstuff and Cascade boutique stuff came on the scene, I've thought it was only a matter of time until sram made a brake that could at least equal the supposed power of trickstuff but at a more realistic price point.

I run the Cascade North Fork calipers and they do feel more powerful, but I wouldn't say its an enormous night and day difference. I've never tried the Trickstuff Maximas but do wonder how much better they can really be.

The fact that Cascade basically just made a caliper using larger pistons to be used with the code lever, I've always been expecting Sram to simply do the same with something mass produced and probably kill off Cascades caliper. Nothing stopping them from doing it...

The new black caliper does somehow look a lot bigger than the current code caliper. I'm wondering how big those pistons will be.

I've got to say I've always expected a new Code caliper to pop up that does the same thing as ours. Hasn't happened yet. Kind of funny considering it's specifically designed to work with Sram parts you can find in bike shops. Whatever this new Sram brake is will determine the future of our Code caliper.

I think the upper limit on brake power will be set by what is a reasonable amount of pad retract. I can't foresee people being okay with pad rub all the time so I don't think pad retract can get much less that what we use on our calipers. If you assume all calipers can be fitted with pads that have the best possible stopping power, braking power then just becomes a ratio of piston area to master cylinder area. The larger you make that ratio the more lever throw you have for a given pad retract. The only way to keep lever throw in check with a larger ratio is decreasing pad retract. Stuff like Swinglink can help, but the more aggressively you make it move through low end braking the more hand fatigue you get riding trails where you're trailing the brakes a lot. This is something we are pretty transparent about with our brake cams. You could potentially have a brake caliper with higher ultimate braking power than another that actually results in a higher average finger force in typical riding conditions. That's when this sort of mechanism would have gone too far. Max braking might be a 3000ish psi but more often than not you're at 1/2 to 3/4 of that. It's really only accessible when you're braking in a compression or the wheels just lock up.

It is matter of time when there will be available aftermarket adapter for non UDH frames (atleast for big players) IMO.

5DEV was teasing the new cranks design as well. They will be available after sea otter.

Anybody working on increasing the friction coefficient between the pads and the rotor? Seems like this would be a possible path towards more power (if it's really needed considering the grip issue you mention). Or towards more pad retraction.

Isn't that the new lever that's already out? Someone mentioned earlier it's just a "pushed back" Code RSC. The fat part looks just like my normal Code RSC lever.

GODDAM this is annoying. The whole point is that thanks to the rear mech mounting to the axle a hanger is NO LONGER NEEDED. The frames still use a UDH mount and tolerances that have been in use for years now. How many UDH frames have you seen where the axle doesn't thread in due to mis alignment? how many frames have wheels off centre due to bad UDH tolerances? The square root of F'All. Most misalignment comes from poorly produced.....................hangers. If the mech is out of alignment with this system, there is a whole lot of F'wittery going on.

Now let's think about the whole direct mount ruining a frame. If you hit a rock hard enough to smash one of these deraileurs, I dare say your frame is going to be ruined anyway....

Some real world experience trickling in...

My buddy has a new SB160 with a set of 2022 Race Face Turbine wheels (straight pull Vault hubs) pulled from his previous bike (Orbea Rallon).

Shop goes to install XX transmission and when they tighten down the rear axle, the cassette rubs the transmission derailleur. After a bit of head scratching, the conclusion is the hub tolerances are off and the hub isn't wide enough on the drive side (my guess is less than .5mm, getting some very thin shims to test it out). Switched the cassette to a different wheel, all worked fine.

The transmission system expects there to be a very specific distance between the back of the cassette (where it contacts the hub) and the end of the hub (where it contacts the derailleur) in order for everything to line up. If those tolerances are off, you've got issues.

The shop called Race Face and they are aware of the issue. My guess is they'll need to manufacture some different end caps to solve the issue.

Anyone else run into similar hub issues yet?

Oh that's an easy fix sir. Transmission was made to be simple to install for any customer and work well from the get go without complicated adjustments. It will adjust itself. Just tighten the axle properly, don't touch the wheel. If it seems to be rubbing, Transmission will push the dropout a little bit to create the necessary space it needs to work properly, and will keep this adjustment perfect forever. No need to play with shims or take out the grinder, just trust your new Transmission, go for an epic ride and enjoy your new trouble-free drivetrain.

Isn't that the new lever that's already out? Someone mentioned earlier it's just a "pushed back" Code RSC. The fat part looks just like my normal Code RSC lever. 

Looks a lot more like a DB8 lever with the swing link and contact point adjustment and rotated under the bar.

Anybody working on increasing the friction coefficient between the pads and the rotor? Seems like this would be a possible path towards more power (if it's really needed considering the grip issue you mention). Or towards more pad retraction.

Hm, aren't there already plenty of pad manufacturers selling pads with varying CoF? And brake rotors with different designs? Like a lot of small holes vs few big holes etc.

Oh that's an easy fix sir. Transmission was made to be simple to install for any customer and work well from the get go without complicated adjustments. It will adjust itself. Just tighten the axle properly, don't touch the wheel. If it seems to be rubbing, Transmission will push the dropout a little bit to create the necessary space it needs to work properly, and will keep this adjustment perfect forever. No need to play with shims or take out the grinder, just trust your new Transmission, go for an epic ride and enjoy your new trouble-free drivetrain.

Solid advice. I’m sure the wheel drag will disappear within the first few miles. Once some pesky metal wears away. Laughing

I'd be surprised if any innovation in this area came from mtb. Automotive (and motorsports) spends a lot more on r&d for this than bike companies ever could.
