Ultegra CS-R8000 Cassette offers Dura-Ace precision and strength at a lower weight and cost
What Our Gearhead® Experts Are Saying:
“This cassette is the best value upgrade in Shimano’s lineup. It shifts flawlessly, lasts forever, and works with nearly any 11-speed setup—from road race bikes to gravel rigs.”
The Shimano Ultegra CS-R8000 Cassette embodies the balance of weight, performance, and longevity that defines the Ultegra series. Precision-machined nickel-plated steel cogs glide through gears with the same effortless smoothness as Dura-Ace, while the aluminum spider carrier reduces weight and enhances stiffness for crisp, instantaneous shifting under power.
With gearing options from tight 11–25t spreads for criterium racers to wide 11–32t configurations for steep climbs and gravel adventures, the R8000 adapts seamlessly to every discipline. Durable enough for high-mileage training yet light and refined enough for race day, it’s the cassette that keeps your drivetrain running flawlessly season after season.
