HG
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 10-speed system, underwent comprehensive optimization to achieve super-highly efficient shifting.

Dyna-Sys

SHIMANO presents the drivetrain technology for mountain bikes: DYNA-SYS. This revolutionary technology uses a 10-speed cassette, but that is not the only feature of this system. Highlight is a completely redesigned drivetrain that creates real added benefits for the rider.
