- XTR M970 crank instalation (it's gone wrong)
one of mine did strip in terms of fitting an allen key so it is worth being cautious- wouod not tighten but it did undo thankfully
I doubt it bottoms out or else they would not give a NM reading they would just say till it wont turn- guessing there tbh but seems to make sense to me
As for your problem sorry not surePosted 4 years agoNorthwindSubscriber
Hmm. Don’t think either of mine has that much play. Not being funny but are you absolutely sure it’s a 73mm shell? (and that you’ve fitted a 2.5 spacer? I once fitted a 1mm one out of basic inattentiveness…) Just to eliminate those…
Right, thinking again about the bolt- the bolt doesn’t bottom out but the arm bottoms onto the axle. Sorry, I could have been more helpful there earlier.Posted 4 years ago
Not entirely sure what I’ve gotten wrong. How tight should the alloy bolt be, bit paranoid of stripping it, does it stop/bottom out completely, or does it just tighten?
Took the bolt off and the axle looks to have bottomed out on the crank arm, but the collar reached the end of it’s threads and just spun. It was fine with an old CK BB 3 spacers and a 68mm shell, but somethings not quite right in the new 73mm shell with 1 spacer and an XTR BB?Posted 4 years ago
