The Stages Power meter is built onto a Campagnolo Chorus non-drive crank arm. This meter comes ready to bolt on, including Campagnolo’s Ultra-Torque non-drive bottom bracket bearing.
Stages Power meters for Campagnolo carbon cranks have been two years in the making and feature a custom developed strain gage that precisely measures your power through the structure of a Campagnolo-designed hollow carbon crank arm.
The new Stages Power meter is slimmer, and up to 28-percent lower profile than our original meter. It's sleeker by way of a 17-percent reduction in frontal area, and we've also made it stronger. The new housing design increases the strength of the battery door and housing connection by 200-percent over the previous design.
