High Performance. Low Weight.

The Shimano Ultegra CS-R8000 11-Speed Cassette provides a wide variety of gearing options with a lightweight, durable construction of nickel-plated steel for seasons of corrosion-resistant riding. Utilizing trickled-down design and technology from their Dura Ace series, the R8000 weighs provides top-tier performance at a slight weight penalty. Featuring the same cogs-on-carrier design for the largest 5 cogs, this saves weight and increases strength.

Designed to provide superior rider choice, there's a R8000 cassette to suit nearly every riding style and terrain type.

  • 12t / 25t (243 grams): 12, 13, 14, 15, 16, 17, 18, 19, 21, 23, 25.

Solid cassette at a great price. Installed on a new wheelset. Shifting is smooth and precise. Does everything it is designed to do well.

I use it for mountain climbing. Long grades above 10% require me to stand in a 34x28, so this just makes the difference between sitting and standing.

Not much to say about a cassette - other than works well, WBW has great prices and fast service - and Ultegra level has great value.

Perfect shifting

The Ultegra cassette has always been the best balance of price and performance. With the release of the 8000 series comes the new 11-30 cassette, which I really loved for cyclocross. Having the 30t was nice to have on steep courses over the 28 but only a little bit heavier.

I have been riding SRAM for the past 10 Years and I changed to Shimano last year. The shifting is smooth as butter and easy on the hands. So far it has been a good change.

Upgraded from an 12-25 105 cassette to an 11-28 Ultegra cassette (hills) and can actually feel smoother shifting with all of the rest of the components remaining 105.

I wanted the wide gear range available in this cassette and also was glad I could get it at a decent price. I have one of these on another bike and it has lasted a very long time. This one should also last a long time. This is a very good cassette that I'll buy again if the need arises.

started to have poor shifting while on the trainer and realized lubrication was not the issue. Worn cassette and idler wheels were actually the culprits. Installed new cassette and idlers-voila! problems solved
