- Durable 7-speed ATB 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 energythrough finer cadence control
- Sprockets are cut away to reduce weight without reducing rigidity
- Nickel-plated finish offers hard wearing resistance to corrosion
- Corrosion-resistant steel cassette lockring
- For 7-speed HG chains
