Hi All,
I foolishly laced up some wheels somewhat recently with some Shimano XT hubs - M785 rear and M788 front to be exact.
Recently, after about 400km's on them, the rear freewheel has started intermittently jamming up. I'll be cruising along and it just sucks freezes and throws the chain off. Sometimes a bit of a clunk will be all it does and it spins again, other times it needs some encouragement. It will occasionally decide it's OK for 30km of riding, sometimes 30m.
Has anyone come across this before and know what the cause is? A quick google search seems to indicate it's moderately common, but no reasons apparent. It seems to be a problem more apparent with clydesdales & hard use too. I'm guessing it's just not up to the heavy abuse as much as it should be.
So, I've learnt my lesson. I'm planning on cutting my losses and just re-lacing the wheel with some Hope Pro2 Evo hubs to be done with it. I've got the time and it would give me peace of mind that I'm not going to rip the mech off mid ride or something.
