I just got a Cannondale road frame (CAAD9) with a BB30 bottom bracket and the seller included the threaded BB adapter, but it is not yet installed. I have a Dura-Ace threaded double, but it is threaded. I am considering selling the Dura-Ace on eBay and buying a compact BB30 crankset. What is your favorite compact crankset for a BB30 bottom bracket (or should I just install the adapter and keep the Dura-Ace)?
