BBB Chainring E-Bike Sprocket for Bosch Motors | BCR-70E
The BBB chainrings are specially designed for Bosch E-bike mid-engined engines. In order to transmit the high torque of the engine without chain drops, the teeth are formed higher than usual. The chain is safer on the chainring and keeps it in the rough terrain on the chainring. For a long life with the relatively large forces of the Bosch engines, the chainrings are made of steel and hardened.
The chainring is suitable for both standard and boost frames and only needs to be mounted accordingly. The permanently integrated spacer ring generates the required offset.
