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. With the release of the new OPI SpideRing MTB SL ring system Integration takes one step further. Available in your choice of ring, offset and arm length. All configurations in stock. Bottom bracket, bolts and Spindle not included. We offer all Bottom Bracket combinations, if you need help please feel free to ask.
Not sure what ring offset you need?
Si: Chainring has an offset (dish) which brings it in towards the frameset. This is the most common configuration, and is used on all Scalpels up to 2016, F29 Hardtails, Jekyll, Trigger and Habit.
Ai: Chainring has very little offset (dish) which appears flat. This is the new system on the F-Si and 2017 Scalpel Si.
