Designed for road racing, the Ultegra cassette offers smooth shifting performance in a lightweight package. Key
Features: 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. Two largest sprockets are mounted on a lightweight alloy carrier to reduce weight & increase rigidity. Sprockets are cut away & drilled to further reduce weight without reducing rigidity. Chrome-plated finish offers hard wearing resistance to corrosion. Steel lockring included. For Super Narrow 9 speed HG chains. Weight: 203g (11
