The Garmin Dual-sensing Upgrade Spindle is designed for riders who want to unlock full left/right power measurement from their existing Garmin pedal-based power meter system. By upgrading with this spindle, you transform a single-sensing setup into a true dual-sensing solution, giving you detailed insight into how each leg contributes to your overall power. This helps you identify imbalances, refine your pedaling technique, and train more efficiently, whether you are preparing for races, long-distance events, or simply aiming to improve your fitness.
Engineered to integrate seamlessly with compatible Garmin power meter pedals, the Dual-sensing Upgrade Spindle maintains the familiar feel and reliable performance you expect from Garmin. It communicates wirelessly with popular bike computers and training platforms, allowing you to track metrics such as total power, cadence, left/right balance, and more. Easy to install and built to withstand everyday riding conditions, this upgrade is ideal for cyclists who already trust Garmin pedals and want to take their data and training precision to the next level without replacing their entire pedal system.
