Hollowtech II in BB30

Postby herzog » 11 May 2011, 11:55pm

After a bit of advice...

I have a Shimano Hollowtech II crankset (Ultegra comact 6700) and I've recently acquired a frame with a BB30. I'd like to use the Hollowtech II cranks on the new frame (Bianchi Sempre), but as I understand it I'll need an adapter. Before I buy anything I'd like to know that I'm not going to be wasting cash by getting the wrong thing. Would this be suitable:
Or this

I'm guessing they are, but would like a bit of advice before purchasing (I've had a bike with BB30 before). Would I have to remove any piece of the BB30 unit before installing the adapter? Finally, what benefits would the more expensive SRAM branded unit give?
