This KMC direct-mount chainring is engineered for Bosch Gen 3 e-bike motor systems. At 38 teeth with an 11/128" pitch and a chainline of 47.5/50mm, it is a precise fit for Gen 3 motor units. The black-anodised aluminium construction keeps weight down while providing the rigidity needed to handle e-bike motor torque reliably. If you're building or servicing a Bosch Gen 3 e-bike, this is the chainring to specify.
