The Bosch E-Bike Gen3 Chainring Connex is an upgraded chainring made in Germany specifically for Gen 3 and 4 Bosch E-Bike systems, giving you the capability to change the gearing ratios on your Bosch equipped E-Bike.
Customize your Bosch Gear Ratios
A perfect upgrade if you find yourself running out of gears while going downhill, or if you find yourself using the smaller sprockets on your cassette often. A high-quality manufacturing and hardening process ensures the Bosch E-Bike Sprocket Connex is extremely wear-resistant and more durable than the original Bosch chainring.
