Shimano CS-HG50 9-Speed Cassette - 12-25T

High quality 9-Speed Shimano CS-HG50 road cassette features cut away and drilled sprockets to reduce weight without reducing rigidity. This cassette is ideally suited to Shimano Sora road groupsets. Designed for Super Narrow 9-speed HG chains, the Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load. The nickel plated finish provides a hard wearing resistance to corrosion and the HG50 cassette also includes a corrosion resistant steel lockring.
