E-Bike Chainring FSA Bosch Gen4 DM Steel MT 1x 38T SH12 WB605 B1

E-Bike Chainring FSA Bosch Gen4 DM Steel MT 1x 38T SH12 WB605 B1

The FSA WB605 B1 chainring is designed for e-bikes equipped with the Bosch Gen4 motor system, where the drivetrain must handle high loads while keeping the chain securely in place. The direct mount design suits modern e-bike setups and helps keep the drivetrain compact, clean and reliable.

This 38-tooth 1x chainring uses the MegaTooth tooth profile to improve chain engagement and reduce the risk of chain drop. That is especially important on electric bikes, where additional motor power and off-road riding loads require precise and stable drivetrain performance.

Made from steel, the chainring offers strong durability and wear resistance for everyday riding, training and trail use. Boost148 compatibility makes it a practical choice for servicing suitable Bosch Gen4 e-MTB and hybrid bikes, replacing a worn chainring or upgrading the drivetrain.
