The first time around, I thought it was just bad luck. No Im beginning to wonder what my problem is.
I noticed the driveside of my XTR external BB was wiggling around as I was descending Avery Creek trail in Pisgah last weekend. I got my bike completely pulled apart tuesday, and all the inner threads were ripped off the driveside cup, hence the wiggling. The BB shell itself was not harmed as far as I can tell, but this has me wondering if others have had similar issues.
Have you?
Since my BBshell is a 68, Ive to use two spacers on one side, and one on the other. Problem is, on the side w/ two spacers, I feel like there really arent enough threads to be stable under truly heavy loads. If I take out a spacer, the plastic sheath inside the bb is simply too long and I can tighten down the bearings. So I have to have the spacers.
Is there anyone that makes cups where the threads go deeper? Also the "L" and the "R" on Shimano bearings are ridiculously confusing...I couldve simply threaded them in backward if that is possible.
Any thoughts?
