Oh it is just a standard external bearing BB with English threads. You pick up a park BB tool for about 25$ and this gets the cups on and off and sets the cranks. Google a YouTube video on how it is done. I upgraded my FSA mega exp to a Shimano 105 for $95 the bike shifts like a dream now. The funny thing is my FSA Carbon light standard double on my Motobecane Imm Spirit shifts like dream also but the cheaper fsa stuff is not as good
