I have run these on both an aluminum Release and an aluminum Catch. I'd contact them directly for fitment on a the carbon model.
These things are awesome, super cheap upgrade for huge improvement in small bump compliance, and they're really cool guys to work with and support.
Best upgrade I made to my bike this season. Bang for the buck at least .
After removing the air and cycling the shock while looking "down the line", the upper mount moves a little at the beginning and end of the stroke. I had also been getting a creak from the suspension that I troubleshooted to the same upper mount.
I replaced both bushings with RWC bearings. The suspension is so much more active now and I haven't had any creaking in almost 2 months of riding. Had to slow rebound down almost all the way since it was kind of pogo sticky at faster settings with the reduced stiction.
I will be cleaning the pivots and inspecting the bearings soon. I'll report any abnormal findings.
I am running one on my 2018 Release 3 on the bottom of the shock only. I am considering an offset bushing for the top to drop the BB and slacken the head angle ever so slightly, still researching that topic right now though.
Anyway, back on topic: The RWC roller bearing is a nice upgrade and I agree that the small bump compliance has improved quite and rear suspension movement feels smoother as a whole.
