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.
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.
