WTB: BB30 Crankset with 170mm arms, 52/36 rings preferred

Looking for a crankset for a bike I am building. Needs to be for BB30 and have 170mm arms. 52/36 rings preferred, but will consider other options.

I have a Sram Force 22 170 mm crankset laying around. Only have 53/39 chainrings though. Can get some pictures later tonight if interested.
