Does the 2011 Specialized Tarmac Pro SL3 frame use a Shimano BB30 Crankset? Or is it something more exotic? I want to change the Std 53/39 to a compact 50/34 to do a hilly tour.
Any help would be appreciated.

The bike as a whole uses the Specialized crankset, which has interchangable spiders. So just pick up the alternate spider for it. Yeah, it's BB30.
