Hyperglide
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.
