Description
Cannondale HollowGram Si Left Crank Arm
The Cannondale Hollowgram crank arm is a modular, high-performance component suitable for mountain, road, cyclocross, and gravel applications. Built around the BB30/PF30 platform, it works with Cannondale spindles, spiders, and direct-mount chainrings for a precise fit.
Hollow forged aluminium construction ensures a lightweight design with exceptional stiffness, delivering reliable power transfer on and off-road.
The Hollowgram sits in the middle of Cannondale’s crank range, offering a balance between the heavier, budget-friendly Cannondale One and the lighter, higher-performance Hollowgram SiSL2. Spiders and spindles are interchangeable across alloy Cannondale cranks.
