E-Bike Sprocket FSA Bosch Ø42.2x3/32x14T WA449 Black

E-Bike Sprocket FSA Bosch Ø42.2x3/32x14T WA449 Black

The FSA WA449 sprocket is designed for e-bikes equipped with the Bosch Gen2 motor system. This compact 14-tooth sprocket is an important drivetrain component, helping ensure secure chain engagement and smooth power transfer during e-bike use.

Electric bike drivetrains operate with higher torque and load than standard bicycle systems, so a correctly matched sprocket is important for reliable performance and riding comfort. The FSA WA449 is a practical choice for replacing a worn component, servicing the bike or refreshing the drivetrain of an e-bike with a Bosch Gen2 system.

The sprocket features a Ø42.2 x 3/32 size and is made for use with Bosch Gen2 drive systems. Its black finish matches modern electric bike components, while the very low 13.1 g weight makes it a lightweight and practical spare part.
