    xtc bottom bracket

    I have a 2000-2003(not sure) Giant XTC. Need a Shimano Octo-link BB for it. I had a 126 it was to long wouldn't shift into the big ring. Found a 118 on E-Bay, I was wondering if this length would do the job.

    I think the crankset determines the spindle length. You can try to find out what length your crankset is compatible with, or if you still have the original bottom bracket, measure the spindle length.

    I got the frame from a buddy and had the XTcrankset laying around. I was using a LX crankset with the 126 BB on a different frame. I will see how the LX crank works on the XTC frame.

    Figure out what the chainline is on your frame and check it to this. 118 should be your max, 113 is possible. Should be the same fore the LX of similare vintage.

    Hey thanks for that chart. The LX was a FC-M572...126 and the XT is a FC-M752...118. I saw those numbers stamped in the crankarm wasn't sure what they meant.
