Technology

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.Â
The HG cassette sprocket, which was developed for the MTB 10-speed system, underwent comprehensive optimization to achieve super-highly efficient shifting.
