Stages GRX RX810 Left Power Meter

The new single-sided Stages Power L meter is built on to a non-drive-side Shimano GRX crank arm and is compatible with all Shimano Hollowtech II road drivetrains.

Stages Power meters are precision instruments assembled by hand at our Boulder, Colorado facility to exacting standards. To us this isn't just the best way to make a power meter, it's the only way. With five Tour de France overall wins along with the Giro d'Italia, Vuelta a Espana and countless other victories in all other cycling disciplines, no other power meter is as tested-or as trusted-as Stages.
