Deore M4100 10-Speed Dyna-Sys cassette featuring light weight minimal design.

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.
