    98 FSR Bottom Bracket Size?

    Hi there

    I want to fit some Race Face Noth Shore Cranks to this bike. but am having problems with sorting a suitable Bottom Bracket. The shell width is 73mm

    The Cranks need an ISIS bb and according to the little information out there, Race Face need either a 113 or 118 mm.

    I have tried a 118mm - but it is way too big - the front mech on maximum extension won't reach over the top ring,so I doubt that a 113 will do.

    I think I need a 108mm but can't get one easily to try.

    Specialized say speak to Race Face and Race Face say speak to Specialized!

    Doeas anyone know what Specialized supplied this with?

    What is any one else using please?

    98 FSR's came with a 68mm bb shell. I would have thought 113 would do, but it depends on your front derailleur. Have you adjusted the high limit screw to the max?
    I see hills.

    I want to climb them.
