The Stages Power LR meter is built on to a Shimano Ultegra R8000 crank set, placed on both the drive and non-drive side of the crank in order to independently measure a rider's left and right legs and is compatible with all Shimano Hollowtech II road drivetrains. Stages power meters are precision instruments assembled by hand at Stages Cycling's Boulder, Colorado facility to exacting standards. High-resolution Gen 3 Stages electronics with enhanced signal strength for reliable, consistent data capture and transfer. Both ANT+ and Bluetooth transmission for compatibility with virtually any computer, phone or smart trainer.
Main features:

Active Temperature Compensation (ATC) as standard equipment: Consistency of measurement is the most important feature of a power meter.
