High performance 10-speed cassette
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
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
