High quality 7speed 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. Sprockets are cut away to further reduce weight without reducing rigidity. Nickelplated finish offers hard wearing resistance to corrosion. Corrosionresistant steel cassette lockring. For 7speed HG chains.
