Garmin Rally RK110 Power Meter - Single Sensing | Look Keo

Is the Garmin Rally RK110 the Right Power Meter for Look Keo Riders?

The Garmin Rally RK110 is a single-sensing pedal-based power meter built for riders using Look Keo-compatible cleats who want accurate, reliable power data without replacing their entire drivetrain. Power is measured at the left pedal, and the unit transmits via ANT+ and Bluetooth to compatible Garmin cycling computers, head units, and training apps. Installation is straightforward, swapping in with standard pedal tools, and the cleats function identically to standard Look Keo hardware so your fit and cleat position don't change.

As a single-sensing unit, the RK110 measures left-leg power and doubles it for total power output, which is accurate for consistent pedaling and a smart entry point into power-based training without the cost of dual sensing. If you already train with a Garmin computer and want to add power data, the Rally integrates seamlessly with Garmin Connect and third-party platforms including TrainingPeaks and Zwift. For riders who want to step up to dual sensing later, upgrading to the RK210 left pedal brings full left/right power balance without replacing the entire system. Battery life runs approximately 120 hours on a single coin cell.
