    FSA mega exo omega Bottom Bracket replacement

    Howdy

    I need to replace the above BB and are trying to source an alternative and think a shimano 4500 bb may fit but im not sure. Its a 68mm (the exo) bb but im unsure if the end cups of the shimano are all the same diameter ie are they a universal diameter other than the different thread types

    Thanks for looking

    What BB interface does your crankset require?
    Stupidity got us into this mess - why can't it get us out?

    It's a mega exo bb, which is external.

    OP: Stick with the proper replacement external BB - that would be the FSA Mega exo that is spec'ed for your specific crank (which you forgot to tell us).

    I seem to remember prior posts from folks who swapped Shimano BB's for FSA's due to the FSA BB reputation for lack of durability. OP, did you do a search on the Forum?
