Garmin Rally RS210 Power Meter - Dual Sensing | Shimano

What Does Dual Sensing Add to the Garmin Rally RS210?

The Garmin Rally RS210 is a dual-sensing pedal-based power meter for Shimano road cleat users who want true left and right power data independently measured, not estimated. Both pedals carry strain gauges, giving you accurate total power output alongside real-time left/right power balance that reveals asymmetries in your pedal stroke across different intensities, fatigue levels, and bike fits. That data is directly actionable for targeted strength work, injury prevention, and dialing in your position on the bike.

The RS210 pairs via ANT+ and Bluetooth to all compatible cycling computers and training platforms including Garmin, Wahoo, Hammerhead, Zwift, and TrainingPeaks, and syncs with Garmin Connect for full post-ride analytics and training load integration. The pedals use standard Shimano SPD-SL 3-bolt road cleats and install without any change to your existing fit or cleat positioning. Power accuracy is rated at plus or minus 1% across the measurement range, and battery life runs approximately 120 hours per coin cell per pedal. For Shimano road riders who train and race with power and want the complete picture on both legs, the RS210 is the right tool.
