- 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
- Two 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
- For Super Narrow 9-speed HG chains
