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

i have the measurement for DA hubs written down, but i'll take a digital caliper to the ball bearings again and get back to you if nooone else comes through.

i dunno about the superbe cranks though

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

I'm very tired and shouldn't be typing yet in the morning. I meant Spocalc

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.
