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.

Great range of gears at a good price.

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.

50 miles a week

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.

Smooth shifting

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.

ongoing maintenance

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

Fast delivery.

The cassette is lighter than the 105 version and feels like it delivers smoother shifting. Not as light as Dura Ace but more durable and more value for the money spent.

Reliable smooth shifts

Have these on two road bikes. Cannondale Evo Hi Mods- one with DI2 and the other with Dura Ace year. Pretty simple works well all the time with both set ups. Minor weight penalty vs DA cassette but not noticeable. Have one less adult beverage and you made up the weight difference.

Great for climbing

I had a 11x28. I talked to my coach about the climbs we were planning to do. I switched to this and was happy I did!

Sure, DA is a little lighter, but Ultegra is a far better value.

Love the range!

Quality cassette at a great price! I'm running a standard crank with the 11-30 cassette and love it! I could do 11-32 so I could spin more but not complaining here!
