Shimano Alivio CS-HG51 Cassette - 8 Speed 11-28t Silver

The Shimano CS-HG51-8 cassette belongs to the Alivio series, dedicated to 8-speed drivetrains. Although primarily intended for mountain bikes (MTB), it will also perform excellently on trekking bikes. It is recommended for use with Shimano HG chains, such as CN-HG40, CN-HG50, CN-HG71, ensuring reliable performance and efficiency.

Technologies Used:

• HyperGlide sprockets. The specially designed HYPERGLIDE sprockets feature uniquely positioned shift ramps and tooth profiles, providing better chain control during gear shifts. HG sprockets guide the chain quickly and directly to the next sprocket without overload. Conventional sprockets cause the chain to lift and pass over the sprocket teeth before engaging.
