The Shimano CS-M5100 Deore 11 Speed Cassette 11-42T features a 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.Shimano CS-M5100 Deore 11 Speed Cassette 11-42T FeaturesFor 11-speed HG-EV MTB chainsColour: SilverDiscipline: MTBSpeed: 11 Speed
