The 9-speed Shimano Altus M370 rear derailleur use its Mega 9 Drive Train design to deliver smooth, light action shifting performance.
Mega 9 - The 9-speed gear cluster actualises close ratio gearing without impairing wide gear range.
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, optimising each shift. Perfect tracking contributes to the most accurate SIS shifting.
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 optimisation to achieve super-highly efficient shifting.
