I'm pretty sure the BB that Campy meant for this is the AC-H in 111 mm width. It would be this same width for both English or Italian BB shells. It was intended for Veloce and the other mid to lower gruppos. Should fit the same as an AC-S, just taht the AC-S will be a lot heaver since it has a solid crank axle. These are all sealed BBs. I've had an AC-H in the Woodrup for about three years, no problems, and I have had another one in another bike. I got that one from a CR lister for $10, and another new on final markdown for around $20. Nowhere near as light as a recent carbon-shell Record, but it works great. On Ebay you might also find a Token or IRD BB to the same spec, that should work right and have good longevity. I wouldn't mess with making a cup and cone design, even a Campy, work. Nothing wrong with them, it's just a whole added dimension of compatibility issues to work through.
