Overview

Single-sensing pedal power meter for Shimano SPD-SL road cleats.

The Garmin Rally RS110 is a single-sensing pedal-based power meter for road cycling, compatible with Shimano SPD-SL cleats. Installs like any standard pedal and transfers easily between bikes. A reimagined strain gauge and added gyroscope deliver power accuracy within +/- 1%. Pedal IQ smart calibration monitors when calibration is needed based on temperature and other factors. Up to 90 hours battery per charge. Pairs with compatible Garmin Edge cycling computers and the Garmin Connect app for data upload and updates.
