    So my Bottom Bracket FSA Press fit
    So my next job is to find an FSA to BSA adaptor that is 90mm wide or to decsribe it better 90mm long to fit my 90mm long bottom bracket.

      So it turns out GIANT works closely with Shimano and tends to use Shimano BB86 and BB92 bearings a lot.

      So my bottom bracket falls into the BB92 Size. When I measured my Giant Fathom 2 2017 bottom bracket I measures a with of 90mm and a diameter outside the shell of 45 mm with FSA Comet cranks.

        So now the task is to go from FSA / BB96 to BSA

        wondering if is this the way to go PF-41 adapter for Press fit bottom brackets https://lunacycle.com/pf-41-adapter-...ttom-brackets/

        With the BBSHD
