Shimano SLX CS-HG81 10-speed cassette

This is a Shimano SLX HG81 10-Speed Dyna-Sys cassette featuring light weight minimal design sprocket carrier

The 3 largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity

Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load

Close ratio gearing allows a more efficient use of energy through finer cadence control

Sprockets are cut away and drilled to reduce weight without reducing rigidity

For 10-speed HG-X MTB chains
