    • Stages Cycling Power Meter G3 L (GRX R8100)

  • Stages Cycling Power L G3 - GRX R8100

    Designed for accurate results across mixed terrain conditions, this crankarm power meter is specifically engineered to be compatible with all Shimano GRX cranksets. Whether you're training on smooth roads or navigating across rocky gravel conditions, this model helps you to achieve your performance goals with ± 1.5% accuracy in all conditions.

    Single Sided Power Meter

    This sleek model features a single-sided power meter that's integrated into a non-drive-side Shimano GRX RX-810 crank arm. This allows you to benefit from its precise readings and its active temperature compensation. Coming equipped with 200+ hours of battery life, this version is more than capable of handling long-distance training sessions as you ride across the mixed terrains on your bike. One final highlight is it only adds a mere 15g of weight to your crankset, so you can enjoy its performance benefits without weighing down your ride.
