Technologies:
- HyperGlide - specially arranged shifting ramps and tooth profiles that improve chain control during shifting. The result is fast and responsive indexed shifting.
- MEGA 9 DRIVETRAIN - the 9-speed block ensures close gear ratios without compromising a wide gear range.
- Top Swing - because the moving linkage part is positioned higher and combined with a shorter link, stiffness is greater, allowing quick and easy gear changes.
Designed for mountain bikes with a 27-speed drivetrain and a compatible chain.
