Sprocket FSA Bosch GEN2 20T WA647 Silver

The FSA WA647 sprocket is designed for e-bikes equipped with the Bosch Gen2 motor system. As a key drivetrain component, it is built to deliver reliable chain engagement and stable power transfer under the higher torque loads typical of electric bikes.

Made from heat-treated stainless steel, this sprocket offers strong wear resistance and long-lasting durability for regular use. The 20-tooth design is suitable for Bosch Gen2 systems and helps keep the drivetrain running smoothly on city rides, touring routes and everyday e-bike journeys.

The polished silver finish gives the sprocket a clean, high-quality look. With a weight of only 53.0 g, it is a practical choice for servicing, replacing a worn component or refreshing the drivetrain of a compatible Bosch Gen2 electric bike.
