KMC chains feature design characteristics that optimally support the performance of the gear systems. By adapting the tooth profiles to the chain design, the play between the sprocket and chain is minimised – this increases the efficiency of the drivetrain and reduces wear. The hardness grades of the chain and sprockets are also matched, significantly extending the service life of the drivetrain components. KMC’s extremely

robust drive sprockets are perfectly matched to KMC chains. This achieves maximum efficiency, saves battery power and ensures maximum durability with the highest precision.
