- Fox 34 Rhythm Fork, 27.5 and 29- how do I change for different wheel sizes?
I have one of these forks on a Cube Reaction 650b bike from 2019. Nice fork, but I may be installing it soon on a 29er.
The label on the side does say “Fox 34 Rhythm 29/27.5”, so it would indicate some adjustability. On the Cube website, its described as “Fox 34 Rhythm Tapered, 15x110mm, 130mm, 2-Position Sweep-Adjust GRIP Damper”
Does anyone have any ideas as to how this is done?

Does it say 29/275+? It’s the plus that makes the difference I think. 275 plus tyres use the same chassis as the 29. The standards 275 is a different chassis.Posted 2 months agohappybikerMember
There’s no adjustment as far the chassis goes, if a 29″ wheel fits with space for mud then it’s compatible.Posted 2 months ago
If in doubt, put the larger wheel in, let the air out of the fork, fully compress and check clearance between tyre and fork crown.Posted 2 months ago
Onzadog- it does indeed say 29/275+. I will test with a 29er wheel as you suggest.Posted 2 months agoRamsey NeilMember
Virtually all 29er forks that are boost will take a 27.5+ as well . You could fit a regular 27.5 wheel in but you will end up with a spectacularly low bottom bracket and a pretty much unrideable bike .Posted 2 months agocynic-alSubscriber

Odd because this fork is 29/27.5+ but the bike has regular 27.5″ wheels fitted as standard. It doesn’t have a low BB and rides pretty well.Posted 2 months agoBearBackMember
Looks like that cube came with 2.6 kendas.. so ‘almost’ 27.5plus.
Any adjustability beyond the amount of travel, moving between wheelsizes would mean changing the length of the cast lowers. Obv this isn’t happening.
I expect cube have designed the frame to suit the 29er fork geo and given you the option to run a 3.0 tire?Posted 2 months ago
I think you’re right, BB. There’s plenty of room.Posted 2 months ago
