Technology
HG Sprockets
The distinctively designed Hyperglide sprockets incorporate specially positioned shift ramps and tooth profiles for improved chain control during shifting. Fast and responsive indexed shifting is the result.
The HG cassette sprocket, which was developed for the MTB 10-speed system, underwent comprehensive optimization to achieve super-highly efficient shifting.
- HG Sprockets - Guide the chain quickly and directly to the next sprocket without override
- Conventional Sprockets - Cause the chain to ride up and over the gear teeth before engaging the sprocket
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.
