Technology
sis_shimano_index_system

SIS Rear Index Shifting System

The system constituents such as the index mechanism built in the shifting lever, the frictionless SIS rear index shifting cable and the smooth action rear derailleur realize the SHIMANO INDEX SYSTEM.

double_servo

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 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.
