The FSA WB671‑42T Megatooth chainring is specifically designed for e‑bikes with a Bosch Gen.3 motor and delivers maximum power transfer along with precise, quiet chain movement. Thanks to its direct‑mount interface, the chainring is mounted directly onto the motor without the need for a spider. The innovative Megatooth profile with extra‑long teeth and alternating wide and narrow tooth shapes (narrow‑wide) ensures optimal chain retention and increased power engagement. This results in efficient power transmission and significantly reduces the risk of chain drops - ideal for demanding trail riding as well as everyday use.
