I am thinking of getting a used 2011 BMC SLR01 and am pricing out how much it would cost to swap frames. PBK.com is asking me if i want 42mm or 46mm ultra torque cups? anyone know which are proper for that frame set? currently running chorus 10 cranks...

Well that frameset should be BB30 so you'll need the 42mm ones (IIRC the 46 is for PF30). However I had a 2011 SLR01 which came from the factory with a BSA threaded adapter pressed in. So I would double check to make sure it hasn't got one of those.
