Deore M5100 11-Speed cassette featuring light weight minimal design sprocket carrier. 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 and drilled to reduce weight without reducing rigidity. For 11-speed HG-EV MTB chains. Average weight: 467 g for 11 - 42T.
