Garmin Rally RS100 Upgrade Kit

Upgrade your Rally RK100 to a dual-sensing power meter, and analyse more than just watts to see exactly how your pedalling style generates the force that moves you. When paired with Rally RK100, the upgrade pedal completes the Rally power meter system, providing left/right balance data and cycling dynamics. The power sensor is even transferable to Rally XC pedals so you can have power for your off-road rides. Revolutionary cycling dynamics display where you’re generating power throughout the pedal stroke and show left/right balance. See where you apply force on the pedal to ensure proper cleat position and track seated vs. standing to see how position changes efficiency.
