The SHIMANO HG81-10 features a refined tooth profile compatible with HG-X chains and range of 10-speed gearing choices for discerning mountain bikers. The latest generation of Shimano's patented & proven HyperGlide cassettes provide dependable shifting with reduced weight. A wider-range 11-36 10-speed HG cassette means riders can climb further in their Primary Driving Gear—the 32-tooth chainring. When other riders have pulled the rip cord, the Dyna-Sys equipped rider will still be motoring along in a more efficient gear with full traction.
