I have a Daytona/ Centaur 10 speed gruppo on my bike. I just bought a Bottom Bracket on ebay that comes in a Daytona box with a 110mm spindle. The 10 speed ISO ST BB AC-H and AC-S are 111mm as is the Centaur BB. I checked the Campy spare part catalog and there is no mention of a "Daytona" bottom bracket, 9 or 10 speed, just the AC-S/H. Does anyone know anything about this BB? I'm not concerned about the mm difference, just curious where it fits in.
