Which bottom bracket
(1/1)
PhilipD:
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

If you are travelling outside of western Europe then I would go for a square taper for exactly this reason.
Some people have had a problem with Octalink cranks (especially XT) clicking once per a revolution. (look on MTBR)
rogerzilla:
Octalink V1 has a design flaw which tends to make the crankbolt loosen (worse than square taper). This is why it's no longer made. In my experience the actual BB holds up OK, and I destroy the normal Shimano BBs with depressing regularity.

+1 - good advice, square taper BBs are also quite inexpensive to purchase
