A high-performance 11-speed cassette for road cycling

The Shimano Ultegra CS-R8000 11-speed road bike cassette is designed for cyclists looking for fast, precise and smooth gear changes. Developed for the Ultegra R8000 ‘Shimano ’ groupset , it features HG-EV technology , which offers a range of gear ratios to adapt the drivetrain to your riding style and terrain.

The CS-R8000 is available in several tooth configurations, including 11-25, 11-28, 11-30, 11-32, 12-25 and 14-28 teeth. This wide choice allows riders to opt either for closely spaced ratios to maintain a steady cadence on undulating terrain, or a wider range of gear ratios for routes with greater elevation changes.

The steel sprockets feature a corrosion-resistant nickel-plated finish, whilst the Hyperglide EVsystem ensures smooth and precise gear changes. The cassette is compatible with Shimano HG-EV 11-speed and HG-X11 chains .

Which cassette should you choose?

The choice of cassette depends mainly on the terrain and your drivetrain.

11–25 teeth: suitable for sporty road cycling on relatively fast-rolling terrain, with closely spaced gears that encourage a steady cadence.

11–28 teeth: an excellent all-round choice for road cycling, offering greater ease on climbs whilst retaining a small 11-tooth sprocket.

11–30 teeth: ideal for undulating routes and cyclists looking for an easier gear range.

11–32 teeth: best suited to rougher or mountainous routes, with a wider gear range.

12–25 and 14–28 teeth: configurations better suited to specific needs, particularly when a particularly progressive gear progression is required.
