I've heard a lot of talk over the years about Sun Tour Superbe BB's being "different". I think this started at Rivendell. What was different about Superbe? I thought the original Superbe crank was just a rebadged Sugino Mightly, which AFAIK was a total clone of Campy NR, including the BB. Was the "different" BB only of Superbe Pro? If so, what was the axle length for a Superbe Pro doubel?
