Shimano Ultegra CS-HG800 11-Speed Cassette
The Shimano Ultegra CS-HG800 11-Speed Cassette brings Ultegra-level performance to MTB and off-road riders. The cogs on this cassette are made from steel and plated in nickel. This provides smooth shifting and a balance between durability and weight savings.
The wide 11-34T gear range also means you will have the proper gearing for any type of terrain. The bottom end of the cassette features even tooth gaps for flat or rolling terrain while the top end provides plenty of range for climbing.
This cassette was designed around HG 10-speed freehub bodies but also includes a spacer to make it compatible with HG 11-speed freehub bodies. This makes it a very versatile mixed-terrain cassette.
