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.
• Six largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity.
• Sprockets are cut away and drilled to further reduce weight without reducing rigidity.
• Chrome-plated finish offers hard wearing resistance to corrosion.
• Chrome-plated steel cassette lockring.
• Use with Super Narrow 9-speed HG chains.
• Weight: 256g (11 - 32T)
• Ratios: 11-32t, 11-34t.
