CANNONDALE Si CRANKARMS
Durability and efficiency are the names of the game when it comes down to it with Cannondale, and the HollowGram Left Crank Arm hosts all the features we need for our next mountain or road bike upgrade. This crank arm is for tackling tough trails, speeding down open roads, and trudging through PUDs (pointless ups and downs). It's built with Cannondale's HollowGram technology and works well paired with any SpiderRing and HollowGram spindles.
