Shimano CS-M5100 Deore 11-speed cassette, 11-51T

This Mountain bike cassette is a Deore M5100 11-Speed Hyperglide cassette featuring light weight minimal design sprocket carrier

The Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load

Brompton compatibility:

We used the first 5 sprockets of this cassette (11/13/15/18 and 21T) to convert our Brompton P Line from a 4 to 5 speed, giving better climbing ability

The close ratio gearing allows a more efficient use of energy through finer cadence control

Weight reduction is made by using cut away sprocket which maintain rigidity

For use with 11-speed HG-EV MTB chains
