has anyone got a new 12speed xtr on a dt swiss microspline freehub? when im tightening up the cassette to 40nm it sounds bloody awful, like its binding, not meshing and generally a very horrid sound, also as I tighten down the torque wrench it feels crunchy is best as I can describe, it doesn't take an awful lot of leverage to get the click on the torque wrench either, so it doesn't even feel like ive done it to 40nm basically
ive checked cleaned and regreased the splines etc, its all line up correctly as far as I can see
don't get me wrong, it works fine, and when I take the cassette off I expect to see loads of marks etc on the freehub, but theres nothing....it just sounds so wrong like somethings not right
Anyone?
I have that combination but when I installed it I don't recall it sounding any worse than any other shimano cassette. They always seem to grate a bit when tightening them up. Did you get the plastic spacer, I didn't and ended up using one from my parts bin? Before that the cassette was loose on the freehub.
hi enmac - cheers for response
yeh got that really thin spacer behind the cassette, the one they decided folk needed after, its only thin but have defo got that on, and yep got the 1 spacer (plastic or metal cant remember) for mid way down the cassette
that's a better word to describe it, sounds like grating, grating metal at that, not pleasant, had to keep taking it off just make sure it wasn't mashing up the threads inside it sounded that bad
As an exshop mechanic and ex pro downhill team mechanic, I've never, in 20 years, torqued a cassette to what it say's too, it's about having a sense of what is tight and what is rite,by the sounds you've gone too far..., Take off the cassette and check for scoring on the bearing retainers, perhaps the treads on the locknut are too deep for Dt Swiss hubs? Microspline is a new standard, you've got to accept these issues
