Shimano Index System (SIS):
SIS Rear Index Shifting System: The system constituents such as the index mechanism built in the shifter, the frictionless SIS rear index shifting cable and the smooth action rear derailleur realize the Shimano Index System.
Double Servo:
Shimano’s double servo-panta mechanism enables the rear derailleur to move in an optimum path.
The guide pulley tracks the cogs closely while moving front to back, optimizing each shift. Perfect tracking contributes to the most accurate SIS shifting.
Keeps rear derailleur guide pulley an optimum distance from each sprocket.
HG Hyperglide:
HG Cassette: The distinctively designed Hyperglide cassette 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, which was developed for the MTB 10-speed system, underwent comprehensive optimization to achieve super-highly efficient shifting.
Guide the chain quickly and directly to the next sprocket without override.
Conventional Cassette: Cause the chain to ride up and over the gear teeth before engaging the sprocket.
