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 originally 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.
