• 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
• 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
• Nickel-plated finish offers hard wearing resistance to corrosion
• Pearl-bright steel cassette lockring
• For use with Shimano 10 speed road bike chains
• Fits 9 or 10 speed Shimano compatible freehubs
