Do I need to get a new bb too?

I currently have FSA gossamer crank, sram rival bb, GXP. probably english threads but i'm not 100% sure. Frame is aluminum if that helps.

Thanks

It depends on what crank you are putting on it.

i am putting in the exact same crank, just a compact

you need a mega exo BB to use the FSA Crank. GXP works with Sram and truvativ cranks. GXP BB + FSA crank = Fail

The way i have it now, it came that way when the bike was purchased.
