Shimano Altus - Front Derailleur - Top Swing- Clamp Band Mount - 3x9-speed
Designed for 3x9 speed drivetrains, the Shimano Altus front derailleur is HyperDrive compatible and available in down swing and top swing versions.
Technologies
Mega 9 Lite
Light pedaling with efficient drivetrain
Optimal gear ratio for each wheel size
The larger the wheel the more range needed in the cassette to maintain light pedaling.
Refined front shifting system
Gear combinations specialised for each tire size reduces the number of recovery rear shifts needed with front close gear ratio.
Tire clearance improved for better maneuverability
Top Swing Front Derailleur -Because the moving pivot section is set at a higher position and combined with a shorter link, the rigidity is higher; so quick and light shifting is possible.
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.
