Rally power meters are tested to the extreme. So you can ride there too. The dual-sensing RS200 measures total power, cadence, left/right balance and where in the pedal stroke you’re applying power to help you ride more efficiently. For single-sensing total power and cadence, check out Rally RS100. Compatible with SHIMANO SPD-SL cleats, the pedals install like any others and are easy to transfer between bikes. When paired with a compatible device, instantly see accurate power measurements on your compatible Garmin device (sold separately) or smartphone, and review later on the Garmin Connect app. View your data on Strava, TrainingPeaks and Zwift for further analysis, sharing and more.
