KMC - E-Bike (BOSCH GEN 4) Chainrings

KMC - E-BIKE (BOSCH GEN 4) CHAINRINGS

A drive is efficient when chain and chainring work together perfectly. The most important factor here is an optimum form and force fit, which is created by a minimum of play between the drive components. Precision is the central KMC issue in the development of advanced drive components. For the Bosch Gen4 chainrings, for example, they designed a completely new tooth profile: It prevents the chain from falling off without forcing it onto the teeth. The result is the perfect balance of power and smooth running with a long service life.
