  • Opinions on bb30 crank (Sram Rival) on a BSA BBed frame?

    The "BB30" cranks which are really 386Evo are fine, they use normal BB30 bearings in cups which screw into a BSC shell just like GXP or HT2 but a bit bigger. True BB30 cranks in a BSC shell should be avoided like the plague.

    AFAIK, SRAM "BB30" cranks except Red Exogram are really 386Evo and use spacers to take up the slack when installed in BB30 or BBRight shells.

  • Cool, many thanks.
    One would still need one of the bsa30 BBS then of course?
    There's cheap ones from China. Avoid or chance it?
