High performance Hyperglide+ 12-speed 105 Road 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. 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. Nickel-plated finish offers hard wearing resistance to corrosion. Pearl-bright steel cassette lockring. .For Super Narrow 12-speed chains
