Recently purchased a set of FSA Powerpro Cranks from MAXTHEROTTI and want to find out what B/B I need for them. Can't post pics till later and all i can tell you is that the end that fastens to the B/b has a square hole in it and I want to fit it to an Orange P7 from '95. Hope one of the retro experts can advise me :?: . Cheers guys. GAZ.
