REGINA 525 HPE - Drive Chain - 128 Links 137HPE/1010

525 HPE - Drive Chain - 128 Links 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 friction, Eliminates the need of periodic re-lubrication, while ensuring at least the same mileage obtained with a normal chain regularly lubricated every 310 miles, Reduces energy dissipation and increases efficiency in the chain drive, Eliminates lubricant spatter during operation, minimizing environmental impact, More power to the wheel, Money savings on lube, fuel consumption and bike cleaners, Combines high hardness with a low coefficient of friction, For use with steel sprockets only.
