The Shimano Ultegra CS-R8000 11-Speed Cassette Sprocket (11-30T) stands as a testament to Shimano’s commitment to delivering superior performance and precision engineering for road cyclists seeking to push their limits. This cassette is tailored to meet the demanding needs of competitive racers and passionate cyclists who require smooth, reliable shifting, optimal gear range, and long-lasting durability on every ride.

This 11-speed cassette features a thoughtfully designed sprocket arrangement ranging from 11 to 30 teeth, carefully crafted to offer an extensive yet finely tuned gear range. The smaller sprockets—starting at 11 teeth—enable explosive acceleration and high-speed sprints, while the larger sprockets up to 30 teeth provide a mechanical advantage for climbing steep gradients with reduced exertion. The intermediate gears ensure seamless cadence transitions, supporting an efficient pedaling rhythm regardless of terrain or riding style.

A core feature of the CS-R8000 cassette is Shimano’s innovative Hyperglide technology. This system incorporates ramped and profiled sprocket teeth engineered to precisely control the chain’s movement during shifts. By smoothing the chain’s transition from one sprocket to the next, Hyperglide minimizes shift effort and drivetrain noise, allowing riders to shift confidently and cleanly even under heavy torque or demanding conditions. This results in a more responsive, fluid riding experience that enhances control and power transfer efficiency.

The cassette’s construction employs high-quality alloys and a nickel-plated finish, striking an ideal balance between weight savings and robust durability. These materials resist wear, corrosion, and fatigue, ensuring consistent performance across extensive mileage and diverse weather conditions. The durable build quality ensures the cassette maintains its integrity, shift precision, and longevity throughout rigorous use.

Compatibility is a key aspect of the CS-R8000 design, fitting seamlessly with Shimano’s 11-speed road groupsets—including Ultegra and Dura-Ace—and standard Shimano freehub bodies. This ensures hassle-free installation, easy upgrades, and replacement options for riders seeking to optimize their drivetrains with genuine, high-performance components.

In sum, the Shimano Ultegra CS-R8000 11-Speed Cassette Sprocket (11-30T) blends cutting-edge technology, precise engineering, and versatile gearing into a single package designed to elevate every ride. Whether you’re sprinting in a criterium, tackling challenging climbs, or enjoying long-distance endurance rides, this cassette delivers the smooth shifting, durability, and gear range needed to maximize your cycling potential and performance.
