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. Nickel-plated finish offers hard wearing resistance to corrosion. Corrosion-resistant steel cassette lockring. For Narrow 8-speed HG chains.
