CS-M5100 Deore 11-speed cassette, 10-51T or 11-42T

• 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
• 10-51T ratio cassette requires a Shimano RD-M5100 11s Rear Mech to work with the largest sprocket. Older 11s rear mechs are unlikely to be compatible.
