It really depends on the flex stay design. Some stays have more rebound than others. You'll notice newer designs from Cannondale and Rocky Mountain with a thinned out portion to minimize this spring effect. These frames don't need special shock tunes AFAIK.
I have the flexstay stumpjumper which has a pretty beefy stay so Specialized used a digressive tune on the DPS shock to tame it. I tried a off the shelf Fox Float and the snap back was too much.

One of the local XC racers who I worked with races U23 WC went to a training camp last year in europe with a flex stay bike and i started getting messages about how she should set up the suspension as her and her coach couldn't figure it out. She was racing on a medium frame, but she was over all just too light for the way the flex stay was tuned and she just could not get along with the bike. Allegedly, that bikes frame flex was tuned for 140-190ish expected rider weight for best results. So that bike just never worked for her no mater how she set it up. It was always harsh and bouncy no matter what she did.
I think a lot of folks either don’t mind or don’t notice how crappy the flex stay bikes feel. If someone has a recommendation for a...
I think a lot of folks either don’t mind or don’t notice how crappy the flex stay bikes feel. If someone has a recommendation for a flex stay bike that’s especially well designed that I should test ride please let me know. But overall, whatever gains you’re getting by running a flex stay on an XC bike are not really worth the compromise on a proper trail bike. (My subjective opinion.)
I'll use this opportunity to finally come out... as a Canyon Lux Trail owner. I come from enduro and ride a mullet Spectral with a coil. I started getting into big rides too and figured I'd get a second bike for just that. I can run the Lux's suspension a bit softer and run the middle lock position when I want more support, but man I have been genuinely blown away by how good the suspension can feel in the full open position. For context, I call very very rocky Arizona trails home

Hello, this is Kayaba Corporation.
Introducing the new suspension we've developed for e-Bikes.
Rough roads, wet roots, rock-strewn trails, no matter how harsh the environment, Kayaba's new e-Bike suspension gives the rider peace of mind and enables them to ride as they wish.
This product is based on motorcycle suspension technology and has a design optimized for e-Bikes. By precisely controlling friction and damping force, the tires grip the trail firmly and provide high traction performance in all conditions. It uses low-friction oil seals and bushings made in Japan, and the front fork uses the same piston slide structure as a motorcycle to achieve a smooth and stable stroke. In addition, it is equipped with Kayaba's unique valve system (※) to provide optimal damping force according to the speed range (※ Patent number: JP2010-242965).
There is no compromise on handling performance either. The crown shape designed through topology optimization analysis and the large 20mm diameter axle shaft ensure torsional rigidity, achieving direct and stable response to the rider's input.
It also has excellent durability, and the inner and outer tubes are made of lightweight, high-strength 7000 series aluminum. High-quality oil seals and bushings made in Japan, and the same structure as motorcycles, ensure high performance over the long term. In addition, the fork guards provide excellent protection for the inner tubes, allowing you to use it safely even in harsh environments.
The bike also offers a wide range of adjustments to suit each individual rider. The front forks feature a hybrid structure that combines replaceable coil springs and air assist, allowing for precise settings. The bike also features rebound and compression adjustments, and is flexible enough to accommodate both 27.5" and 29" wheels.
Rear shock: Total length: 210mm Stroke: 55mm Damper adjustment: Low speed/high speed compression/rebound Spring: Coil, with preload adjustment mechanism
Packed with Kayaba technology, this suspension further expands the possibilities of e-Bikes, taking riding fun and freedom to the next level.
[Exhibition and test ride information] We will have this product on display and test rides available at the "SHIMANO ENS 2025 #3 IWATAKE" to be held at Hakuba Iwatake from Saturday, June 28th to Sunday, June 29th, 2025. We will also be giving away original goods as gifts. Please stop by the Kayaba booth.
Bumped into someone who works for a major bike brand. He says their XC 32in bikes are already ready for 2026. They are currently test riding them with modified USD forks. They are waiting for FOX and Rockshox to come out with compatible forks. Maxxis is still getting their 32in tyre range done. Apparently, their taller XC racers are already sold on the new bikes. 32in front and back and also 32in and 29in mullet. Though probably no big wheels on sizes S and XS. He says he expects a lot of 32in stuff to show up at Eurobike.

E-bikes and relatively low power lightweight electric motorcycles will be the main transportation method for large parts of the world. Imagine replacing every 2 stroke engine in a Vietnamese city with something clean. Once the tech is affordable enough it would mean a massive improvement in air quality and noise. So what’s a niche or recreational market in some places can be the norm in others.

It’s also a marketing opportunity for them. They use existing resource and leverage partnerships for some kind of increased revenue stream and they reach a new audience who now has name recognition of the brand. Also agree with bulletbass that it’s a long game as well.
Question for the Boxxer people: does this look normal, or is Luca Shaw running some sort of added chamber on the top of his spring side stanchion?
Picture comes from a bike check post on Luca's Canyon Sender from the other site. Looks like it could be an added volume cap for the positive air chamber, like the MRP Noken or Ratio Flux Cap we tested on Vital.

Sounds in the ballpark for the new fork - they run way higher pressures due to the smaller chamber diameter and large negative spring. An average dude would be in the 170psi bracket so someone like Luca could easily be at 200, especially if that has a larger positive chamber
And no, that doesn't look like a normal rockshox part

I had a buddy send me a picture of the lower half of a production final USD fox fork. He works at a bike shop. Seems its launching very soon.
3 more sleeps.
Seen this at Bikepark Winterberg on a Santa Cruz V10, never seen a V10 with this setup before.
Looks like a lot of chain slippage.
Shocker! Wasn’t it a „prototype“ just weeks ago 🤣
It may help somewhat, but damn, it’s only making contact with like 3 teeth
The modified one is shown in Blue
That V10 scares me.... odds of it skipping when you lay the power down is absurdly high!
We spent so much time worrying about pedal kickback that we didn't stop to consider pedal kickforward
Damn, yet another automative company getting into bicycles ! Curious as to why, surely MTB is a pretty niche and not very profitable market compared to cars

I think we going to have air shock from fast
I believe that’s a Formula Nebbia
https://www.rideformula.com/products/mtb-shocks/nebbia/
I see purple and think fast, not formula. My mistake
discuss the topic of energy in a different thread.
https://www.vitalmtb.com/forums/VitalMTB/Off-the-Bike,3
Is this saying there is more or less pedal kickback with this modification?
Less pedal kick with mod but less pedal efficiency, it will bob a lot

And 200 psi…
Is that low or high for the new fork?
Sounds in the ballpark for the new fork - they run way higher pressures due to the smaller chamber diameter and large negative spring. An average dude would be in the 170psi bracket so someone like Luca could easily be at 200, especially if that has a larger positive chamber
And no, that doesn't look like a normal rockshox part
So unlike the Zeb the Boxxer has a cartridge?
