Technology
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 specialized for each tire size reduces the number of recovery rear shifts needed with front close gear ratio
- Tire clearance improved for better maneuverability
Octalink
Compared the power transfer of Octalink with the conventional square taper spindle, the 8-splined Octalink interface that connects bottom bracket and crank set increases the strength and rigidity for entire assembly.
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.
- HG Sprockets - Guide the chain quickly and directly to the next sprocket without override
- Conventional Sprockets - Cause the chain to ride up and over the gear teeth before engaging the sprocket
