This seems like a bit of silly question, but in 25 years mountain biking I’ve never had a single freewheel problem, soÖ when they play-up or fail do they fail to engage or fail to disengage?
Also, is it likely that the freewheel might intermittently fail and give a skipping/drive failure moment?
And finally (sorry) is it possible that this is all a result of keeping the bike in a flippin’ freezing shed and it never having an opportunity to thaw?
Basically I’ve got drive skipping problems and I don’t think its the usual suspects, because rings cassette and chain are all new and correctly fitted/adjusted. I think.
