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.
