Designed for 9-speed trekking drivetrains, the Shimano Alivio T4000 derailleur delivers light, precise shifting.
Technologies
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.
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.
