That's what BB30 technically is, but the information I was giving applies to 73mm and 86mm BB shells as well. I installed a lot of Shimano cranks in BBRight Cervelos using Wheels adapter inserts, and they held up very well.
The metal adapter BBs work fine, but occasionally fail to come apart properly when you want to service or replace them.
