Shimano Ultegra CS-R8000 Cassette

The Shimano Ultegra CS-R8000 cassette is the logical and reliable choice for the roadbike rider focused on high-end performance. As the flagship of the 11-speed Ultegra line, this cassette combines low weight with the unmatched durability expected from Ultegra. The larger cogs are mounted onto two lightweight aluminum spiders. This not only significantly reduces weight but also enhances the lateral stiffness of the cassette, which is crucial for efficient power transfer and flawless operation during sprints or accelerating out of corners.

The core of the CSR8000's performance lies in Shimano's HyperGlide EV (HG-EV) technology. This advanced tooth profiling and cleverly positioned shift ramps ensure the chain moves with exceptional precision and speed from one cog to the next, even under heavy load. The result is virtually shock-free shifting that keeps the rider's cadence consistent. This reliability makes the ShimanoUltegra cassette the preferred choice for both competitive roadbike racers and long-distance cyclists who demand durability and precision.

The Ultegra CS-R8000 offers wide compatibility and is available in an extensive range of gearing, from tight race ratios (like 11-25T) to very wide options (up to 11-34T). The wider ratios make this 11speed cassette suitable for mountainous terrain or light gravel use while maintaining crisp, performance-oriented steps. The combination of lightweight construction, high stiffness, and proven durability makes the CSR8000 the standard for every modern roadbike.
