Joewrote a review of Rotor ITA 30 Bottom Bracket on February 8, 2018
Leaving aside Campagnolo, there are two iterations of 30MM crank spindle: BB30/PF30 and BB386EVO. Rotor's factory site claims that this BB will work with either one and that is a significant claim if you happen to have an Italian threaded shell. Unfortunately, FSA BB386EVO carbon cranks (SL-K) bind badly with these cups apparently due to internal tolerance and the width as well. A call to the FSA techs at HQ confirmed same: There is NO FSA BB or any other BB known to be both ITALIAN threaded AND compatible with the FSA carbon 386EVO crank. (FSA does make one for the alloy Gossamer crank.) Using a 30MM crank other than the FSA 386EVO may be fine.
