Ultegra CS-R8000 Cassette delivers pro-level performance with lasting value
What Our Gearhead® Experts Are Saying:
“The CS-R8000 shifts as smooth as Dura-Ace but saves you some serious cash. It’s durable, quiet, and gives you all the range you need for everything from steep climbs to flat-out crits.”
When precision and dependability matter most, the Shimano Ultegra CS-R8000 Cassette gives us the same crisp, reliable shifting found in the brand’s top-tier drivetrains—without the premium price tag. Designed for riders who demand performance across every terrain, it offers a wide range of gearing options suited for racing, training, or tackling long climbs.
Each cog is nickel-plated steel for durability and smooth transitions, mounted on a lightweight aluminum carrier to keep the weight down. Whether we’re grinding up alpine passes or sprinting for the line, the R8000’s perfectly tuned shift ramps deliver that signature Shimano feel—quiet, precise, and utterly reliable mile after mile.

Ultegra R8000 11-25
- Familiarity:
- I've put it through the wringer
11-25 Ultegra R8000 works perfectly, even with my long cage ultegra R8000 rear deraillure. Seriously works PERFECTLY!

Still the best

- I've put it through the wringer
High quality, light, easy to install, good price, smooth shifting and comes in a wide range of tooth options. I use the integra cassettes on both my ultegra and 105 rigged bikes; bought this one for a gravel rig I am building. No complaints ever.
