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.
• Average weight: 351 g for 11 - 34T.
