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 tyre size reduces the number of recovery rear shifts needed with front close gear ratio.
Tyre clearance improved for better maneuverability.

HyperGlide 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.

Shimano Shadow RD – The mechanism rear derailleur, Shimano Shadow RD, is intended for more aggressive riding. Its super low profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
