Campagnolo Super Record 12 L Gen 3 Power Meter Crank Arm

Stages keeps up with the latest so you can get the power data you want and need without having to compromise your Campagnolo Super Record 12speed group to a third party crank. Stages builds their Gen 3 power meter into a Super Record 12 left-side crank arm for seamless swapping from a stock to power meter unit. Training with power pays heavy dividends if you want to get fast and race harder and with only a small power sensor located on the inside of the left crank arm. You end up with a reliable power measurement device without losing that wonderful Campy carbon mystique and super smooth spinning ceramic bearings.

Replacing the left arm with this unit is pure plug-and-play and the included meter's technology that's housed within the small pod is what the pros rely on during training and racing. Strain gauges and an improved accelerometer measure force and rotations to deliver power data to your head unit with a claimed accuracy of +/-1.5%, which is inline or exceeds other quality power meters on the market. It also incorporates Stage's Active Temperature Compensation (ATC), which compensates for the natural expansion and contraction of the strain gauges providing more accuracy and won't fluctuate with the change in external temperatures. ATC is also handy in that it adjusts at the start of the ride and compensates without requiring you to continuously zero the system. Overall, the power meter adds less than 15g to the crank, which is next to nothing for the ability to chart limits, plan training regimes, and monitor efforts on race day. Improved ANT+ and Bluetooth connectivity, over Gen 2 power meters, delivers a signal 6 times more powerful to the head unit of your choice.
