Garmin Rally 210 and 110 Power Meter Pedals Reviewed
Garmin's fifth-generation Rally 210 and 110 pedals land with two headline changes: built-in rechargeable batteries and a universal spindle that fits most crank systems without swapping axles. That second point matters more than it sounds. Previous Rally generations required buying pedal-specific versions for Shimano, Look, or SPD-SL cleats, which pushed costs up fast.
Battery life sits at 90 hours on a single charge. That beats the Favero Assioma Duo's 60-hour rating and removes the coin-cell anxiety that older Rally models carried. Accuracy is claimed at plus or minus 1%, matching the Assioma Duo and sitting level with Wahoo's Speedplay Power pedals. For most cyclists training with power, 1% is more than precise enough.
The new Force metrics are the technical talking point. Garmin tracks left-right power balance, pedaling smoothness, torque effectiveness, and now adds lateral and fore-aft force data through what they call Pedal IQ calibration. Paired to a Garmin Edge or compatible head unit, you get a clearer picture of pedal stroke efficiency than the Assioma's app-based analysis offers. Whether you act on that data depends on your coaching setup.
Price is where it gets harder. The Rally 210 dual-sided sits above the Favero Assioma Duo on street pricing, and the Assioma remains the benchmark for value in this category. If you are already deep in the Garmin ecosystem, the native data integration justifies the gap. If you use a Wahoo Elemnt or train primarily on feel, the premium is harder to defend.
Solid upgrade over the previous Rally generation. The rechargeable battery and universal spindle fix the two biggest complaints. Not the value leader, but the most complete Garmin pedal yet.
