This sensor connects directly to the yellow output of the motor and automatically cuts motor assistance when changing gears, thus avoiding the impact of the chain on the chainrings. A perfect addition to our kits, it effectively protects your derailleur by cutting off the engine at the right time. Be careful, if your derailleur cable is damaged, prefer the version equipped with a cable because the cable must pass through the sensor, and a frayed cable would prevent correct operation. Ensure the longevity of your transmission with this simple and effective solution.
