E-Bike Chainring KMC Bosch Gen4 34T Chainline 52.0
The KMC Bosch Gen4 34T chainring is designed for e-bikes using the Bosch Gen4 system and a direct mount interface. It is a precise and durable drivetrain component that helps keep chain movement stable and power transfer smooth, even under the higher loads typical of electric bikes.
Made from hardened chromoly steel, the chainring offers excellent wear resistance, strength and long-lasting reliability. The Super Narrow profile and 1/2" x 11/128" size are suitable for narrow e-bike chains, providing accurate engagement and efficient power transfer.
The 9.0 mm offset and 52.0 mm chainline make this model a suitable choice for Bosch Gen4 direct mount setups. It is perfectly matched to KMC e1, e12, e11, e10, e9 and e8 chains, helping reduce power loss, improve drivetrain efficiency and save battery energy on longer rides.
