Key Features:

1. Power Measurement:

   • The power meter measures power output from the left crank arm only.
   • It provides accurate data with a claimed accuracy of ±1.5%.

2. Crank Arm:

   • The power meter is integrated into the left crank arm, which is part of the Shimano GRX RX810 groupset.
   • Available in different crank lengths to fit various bike setups.

3. Compatibility:

   • Designed specifically for gravel riding, it fits seamlessly with the Shimano GRX RX810 groupset.
   • Compatible with both ANT+ and Bluetooth Smart (BLE) protocols, ensuring it can connect with most bike computers and smartphones.

4. Battery Life:

   • Battery replacement is straightforward and can be done without any special tools.

5. Durability:

   • The unit is waterproof and built to withstand the rigors of off-road and gravel riding.
   • Stages power meters are known for their robust build quality.

6. Calibration:

   • Features Active Temperature Compensation (ATC) to maintain accuracy in varying temperatures.
   • Simple zero-offset calibration process ensures consistent data accuracy.

Benefits:

• Single Sided Measurement:

  • More affordable than dual-sided power meters.

Considerations:

• Single-sided vs. Dual-sided:

  • For most cyclists, single-sided measurement provides sufficient data for effective training and performance analysis.

Installation:

• Installation is similar to replacing a standard crank arm. You’ll need a Shimano-compatible crank puller and possibly a torque wrench to ensure proper installation.

• Riders appreciate the accuracy and reliability of the Stages GRX RX810 Single Sided power meter.
• The integration with the GRX groupset means it’s a perfect match for gravel bikes, maintaining the aesthetics and functionality of the Shimano setup.
