Performance & Use Case
The Shimano Ultegra R8000 11-Speed Cassette is the race-tier 11-speed cassette in Shimano's range. Four gear ratio options cover the race-spec spread - tight ratios for criterium and rolling terrain (11-25, 14-28), through general road (11-28) to mixed terrain (11-30). The 14-28 variant in particular gives tighter sprocket-to-sprocket spacing than the more common 11-28, keeping the rider in their optimal cadence range during sustained efforts.
Construction & Materials
Ultegra-grade construction delivers a weight saving over the 105 HG700 while retaining the same Hyperglide+ shifting performance. Sprockets are machined and profiled for smooth shifts under load.
Compatibility & Variants
Shimano HG 11-speed freehub body. Compatible with Shimano 11-speed road groupsets - 105, Ultegra, Dura-Ace. Four gear ratio options: 11-25 (race-tight), 11-28 (all-purpose), 11-30 (mixed terrain), 14-28 (race-tight with mid-cassette focus). Select the gear range that matches your terrain and racing style.
Best cassette Shimano offer. Smoother shifting that the 105, feels crisper, (looks better that the 105) and stronger than the Dura-Ace titanium sprockets at the top of the cassette for a minor weight penalty and massive saving. More expensive than the 105 but if you amortise the extra cost over the life of the cassette it’s definitely worth it. The Goldilocks cassette.
Good cassette - very well packaged and easy to install

From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.
Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
