GRX RX810 Gen 3 Power Meter Left

For focused workouts that yield results, you can't beat the consistency and accuracy of power-based training. And this unit is as low-profile and lightweight as a power meter gets - 15g, with a minimalist housing and sleek front profile. ANT+ and Bluetooth Smart compatibility make it good to go with pretty much any major GPS or cycling computer on the planet. The 3rd generation Stages power meter is more accurate, has an upgraded antenna and now features an LED light to confirm calibration and battery level.
