Ultegra CS-R8000 Cassette

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.
