I've got an older XTR rear hub and the thing is driving me crazy. It used to make a grinding noise. I rebuilt it and it was still there. after a while it went away, but itdidn't hold speed very well. Rebuilt again and it's pretty smooth but it is still very slow, and sort of makes a pinging noise when being ridden, but nothing while it's in the stand.
I planned on getting new cones but it's too old to get a full set and I can only get the left cone.
Any suggestions? Anyone have an old rebuild kit or an xtr hub I can bastardize?
