HG Road 10-speed Chain
The inner outer plate, designed for better contact with gear teeth, allows smooth shifting even under high load conditions. In addition, the chain has achieved a pedaling efficiency of 0.6% higher.
In order to obtain good gear shifting performance, this chain has a forward side and a reverse side, and the sides are marked so that the chain will face the correct way when installed.
