I'm building up an expedition touring bike. All is in place and I have chosen an XT groupset as my experience with these in the past has been good. However, the octalink bb I installed very rapidly gave up the ghost.
Should I replace the octalink or go for one of the new external bearing system sets? What are peoples' experience of these? Part of me thinks I should revert to a good quality square taper set as at least these can be found anywhere with ease.
Oh, before you mention it, I know I'd be better off with a rohloff, but I think the raven nomad of my dreams is good while off just yet!
Thanks
Philip
