Light, extremely stiff and stable aluminum crank from Cannondale. The HollowGram is made from one piece and hollow using a special forging process. This means that the crank arms are about as light as those of the first HollowGram SI generation but just as versatile. Due to their modular design, they are versatile and can be combined with different shafts, spiders and chainrings.
- 170 mm
- Bolt not included.
