At Infinite Cycles, we love the simplicity and high performance of the Cannondale Hollowgram. When they came out with the updated SiSl2, it only got better. Compared to other leading top-level cranksets, the Hollowgram SiSl2 comes out ahead on weight, but the Hollowgram is more than that. It is more versatile that any other crankset currently available. Thanks to the interchangeable spider and modular spindle system, you can swap from a road compact to a road standard or move to your mountain bike with an XX1 or XX spider. The Hollowgram is light enough for road, tough enough for mountain.

If you’ve already got an older Hollowgram, you can upgrade to the new SpideRing and improve the shifting in a big way!
