Shimano Alivio CS-HG51 8S 11-28 Cassette

The Shimano Alivio CS-HG51 8-speed 11-28 cassette is designed for mountain bikes, city bikes, and touring bikes seeking smooth and reliable shifting. Its riveted steel sprockets with a nickel-plated finish utilize HYPERGLIDE (HG) technology: specific profiles and ramps guide the chain for fast, crisp, and quiet gear changes. Carefully placed cutouts lighten the cassette without compromising its stiffness, and it mounts to standard HG-type freehub bodies with Shimano 8-speed chains. The 11-28 gear range offers a good balance between speed on flat terrain and sufficiently agile gears for moderate climbs.
