Garmin Rally RS100 Single Sided Power Meter Pedals (Shimano Cleats)

Following a meticulous design phase and rigorous real-world testing, the Garmin Rally RS100 Single Sided Power Meter Pedals (Shimano Cleats) realise exceptional durability, accuracy and versatility, helping the dedicated rider train and race with greater effectiveness.

Simple to install and swap between bikes, just as standard pedals are, the power measurement is easily calibrated via a connected bike computer or watch, granting reliable readings instantly. The power measurement instruments are sealed from the elements inside the left pedal spindle, and these measure the watts and cadence produced by the rider's left leg. The system doubles these power numbers to arrive with a reliable estimate of total power, allowing the rider to train with heightened precision.

Data is communicated in real-time to compatible bike computers, watches and indoor training setups via the wireless ANT+ and Bluetooth protocols and can be synced with programs like Garmin Connect, Strava and TrainingPeaks for post-ride analysis and social sharing.

This system arrives supplied with Garmin RS Shimano road pedal bodies, but these can be easily swapped to the Garmin RK Look Keo or XC Shimano SPD off-road pedal bodies (available separately) if the rider ever wants to try different platforms. The batteries offer 120 hours of riding and can be changed easily by the user via the durable metal threaded battery cap.

Should the rider ever want to upgrade to a dual-sided power measurement system, a right-sided power pedal upgrade kit is available separately.

  • 1 x RS100 Right standard (non power measuring) pedal compatible with Shimano road style cleats
