    Powerdrive vs powerspline BB

    Hi Guys.

    Are they Truvativ Powerspline bb's the same as FSA Powerdrive bb's?

    The reason i ask is that i have FSA Powerdrive crank, but my LBS can't seem to obtain a matching FSA bb, however powerspline bb's are reltively easy to get, but i'm not sure if the splines are the same?

    Can anyone shed some light?? There doesn't seem to be any info on the web about compatability of the two formats.

    I hope i'm not confusing anyone!!!

    Thanks.

    I believe the Powerdrive uses 10 splines and the Powerspline uses 12 splines

    Might be time to upgrade
