I am wondering if I can safely take apart and reassemble an XT or XTR cartridge type bottom bracket. (ES-71 XT and M952 XTR)
Here's why:
I have a FSA mountain bike crank that requires XT octalink spindle, not XTR. The XT is significantly heavier than the XTR, though I believe the spindle weight is the same. (they are both hollow cromoly). They just have a slightly different octalink spline. I was thinking of taking the XTR spindle out, and placing the XT spindle in. 40 grams less. Can this be done, and what would I have to do to do this? I have never seen anything on servicing the internals of a Shimano cartridge type bottom bracket.
