Garmin Rally RK100 Single Sided Power Meter Pedals (Look Cleats)

The Garmin Rally RK100 Single Sided Power Meter Pedals (Look Cleats) offers reliability, versatility and accuracy to the serious road cyclist.

Installed in the same manner as regular pedals, and with a simple calibration procedure, easy setup is guaranteed, allowing the rider to start training with accuracy straight away. The easy setup grants quick swapping between bikes without any risk of affecting the power readings.

The power measurement instruments are housed inside the left pedal spindle, completely sealed from the elements and dirt. The spindle accurately measures the power and cadence produced by the left leg and doubles these readings to get a reliable estimate of the total power produced. The data collected is communicated in real-time to compatible bike computers, watches and indoor training formats via the wireless ANT+ and Bluetooth protocols. All of the data can be synced post-ride with programs such as Garmin Connect, Strava and TrainingPeaks for in-depth analysis and social sharing.

Look Keo cleat compatible pedal bodies spin around a spindle design that permits easy swapping with Garmin RS Shimano road or XC Shimano SPD off-road pedal bodies (available separately). This versatility means that one power meter pedal system can cater to any riding style, whether on or off-road.

Either 2 x LR44/SR44 batteries or 1 x CR1/3N battery power the electronics to afford up to 120 hours of riding. When it’s time for a battery change, the user can easily do it themselves via the robust, metal threaded battery cap.

A kit can be purchased separately, including the right power measurement pedal, allowing the rider to seamlessly upgrade to the benefits of dual-sided power-measurement should they deem this necessary in the future.
