Tetrahedral Amorphous Carbon (ta-C) coating is an advanced DLC (Diamond Like Carbon) coating applied on the surfaces of the bushings and the rollers of the HPE Chain, combining high hardness with a low coefficient of frictionEliminates the need of periodic re-lubrication, while ensuring at least the same mileage obtained with a normal chain regularly lubricated every 310 milesReduces energy dissipation and increases efficiency in the chain driveEliminates lubricant spatter during operation, minimizing environmental impactMore power to the wheelEU: Eliminates the need of periodic re-lubrication, while ensuring at least the same mileage obtained with a normal chain regularly lubricated every 500 kmMoney savings on lube, fuel consumption and bike cleanersCombines high hardness with a low coefficient of frictionFor use with steel sprockets only.
