For sale is a great condition set of Cannondale's Hollowgram Si cranks. 175mm length arms, with 53/39t mk IV rings. Cranks have been run for 600 miles or so until I realized I should really be riding 172.5's. I've since purchased a set and thus these are for sale. Only one blemish where the chain hit the drive side arm.

These cranks are unreal as I'm sure your familiar. Lighter and stiffer than Dura Ace, etc... If you have a BB30 bike, you need these cranks.
