Left-sensing power meter for Shimano SPD off-road cleats.

The Garmin Rally XC110 is a single-sensing pedal-based power meter for off-road cycling, compatible with Shimano SPD cleats, the standard for mountain biking, gravel, and cross-country riding. It measures power from the left pedal and doubles for total power, bringing accurate wattage data to riders running SPD two-bolt cleats. The XC pedal body features an all-metal design with a lower stack height to reduce pedal strikes on rocks and roots. Installs like any standard pedal and transfers easily between bikes. +/- 1% accuracy. Pedal IQ smart calibration monitors when calibration is needed. Up to 90 hours battery per charge. Pairs with compatible Garmin Edge cycling computers and the Garmin Connect app.

Upgrade to dual-sensing (XC210) later by adding a right-sensing pod without replacing the full pedal.
