Cannondale's newest Hollowgram Si Forged crank arms pushes the boundry between performance and value. Now closing the gap between SiSL2, the Hollowgram Si Forged crankset features a new forging process, for the lightest crankset in it's class. Available in your choice of gear ratio, and arm length. All configurations in stock. We include the 10 arm CNC'd SpideRing SL on all of our Si Forged Cranksets, which is a huge upgrade over the stock 8 arm forged spider.
