This Stages Power meter is built on to a non-drive Cannondale Si crank arm specifically to pair with Cannondale's Hollowgram Si crank — 2014 or newer. The Stages Power meter will also mate to the Hollowgram SISL2 model crank.

This Stages Power meter is slimmer and up to 28% lower profile than their original meter. It's also sleeker, with a 17-percent reduction in frontal area, and they've made it stronger. The housing design increases the strength of the battery door and housing connection by 200-percent over the previous design.
