Bearing size for Dura Ace hubs and Superbe bottom bracket?

Anyone know what the size is or a resource that has that stuff listed?

It might be worth while to create something like Sporcal with that information.

Aren't 1/4" bearings the industry norm for rear hubs?? Same for bottom brackets.

That's what I thought. But then again we're talking bikes here. Campy ran two different size bearings on their rear hub.

Generally yes but I've seen BB bearings be several different sizes and Campy ran a different size for Record hubs.
