The Garmin Rally XC power meter pedal is a mountain biking power-meter pedal compatible with Shimano SPD cleats (included). The XC 100 measures left-side power only (right pedal is a standard, non-power measuring). Your left-side power is doubled to approximate total power.
The XC 200 measures both left and right side power and provides more in-depth pedal analytics.
Compatible with all bluetooth and/or ANT+ power-reading devices.
