Shimano Deore CS-M5100 Cassette 11-Speed 11-51t, Silver

The Shimano Deore CS-M5100 is an 11-speed mountain cassette with an 11-51t range, giving single-ring drivetrains wide gearing for steep climbs and fast descents. It mounts to a standard HyperGlide freehub body, making it easy to fit on many existing wheels without changing the driver. HyperGlide shift ramps and tooth profiles deliver smooth, reliable shifting under load. The 51t cog provides a very easy climbing gear for trail riding and bikepacking. It pairs with Shimano Deore M5100 11-speed drivetrains and is a durable, affordable replacement cassette for 1x mountain bikes.
