KMC chainring Bosch Gen.4/Gen.5 38T 52mm SFCB145238

The KMC 38T chainring was specifically developed for Bosch Gen.4 and Gen.5 motors, offering maximum durability and efficient power transmission. With its 38 teeth, it's ideal for tackling challenging climbs on an e-MTB, long tours on a trekking bike, or demanding everyday use on a cargo e-bike. Made of hardened chromoly steel, the sprocket withstands even the heaviest loads and, when used with compatible KMC e-Series chains (from e1 to e12), delivers an impressive lifespan of over 3,500 km. The precise 52 mm chainline ensures smooth, quiet operation and optimal shifting performance. Thanks to the direct-mount system, installation is quick and easy. With its clean, black finish, the chainring blends seamlessly into any bike design – technically robust, yet visually understated.
