The perfect gearing for every rider. In addition to picking up an 11th cog, the Ultegra CS-6800 Cassette is now available in more tooth spreads, including a hill conquering 11-32T option.

Redesigned Hyperglide tooth profiles deliver speedy, reliable shifting with the narrower CN-6800 11-speed chain. Steel cogs deliver maximum durability, and machined cutouts offer additional weight savings.

Claimed weight: 212g (11-23T), 292g (11-32T). If a particular gearing of the Ultegra CS-6800 Cassette is unavailable, please check over at the new R8000 Cassette.

Gearing options:

  • 11-23T (11,12,13,14,15,16,17,18,19,21,23T)
  • 11-25T (11,12,13,14,15,16,17,19,21,23,25T)
  • 11-28T (11,12,13,14,15,17,19,21,23,25,28T)

Worked as I expectd
rating

Northern Illinois

My new bike came with an 11-32 cassette. Living in Illinois, I wanted one that had more intermediate gears since I never need the largest 32 or 28 (for example) with a compact crank up front. So I bought the 12-25 which has a 15, 17 and 19 that are missing missing on the 11-32. The largest gear (25) plus the 34 up front gives me plenty of climbing range for the steeper (but shorter) grades I ride here in northern Illinois and southern Wisconsin. Since I travel to Colorado and Arizona occasionally, I will re-install the 11-32 for those trips.

Great cassette
rating

Going up from a 27 to a 28 was a noticeable improvement since most of my rides are climbing and descending. Going to the 11 speed for the new Shimano groupo was a no brainer. The weight savings of the Dura Ace cassette didn't make sense since clusters wear out before other components other than cables and chains. Overall, really happy with the choice.

Shimano Produces Great Results (as usual)
rating

With 11-speed components still being fairly new I am always aware that there may be bugs. This cassette has far exceeded my expectations (though I probably should have know that coming from Shimano it would be great). well made, fits perfectly and moves smoothly. The teeth grip the chain and alow for easy shifting from 1 gar to another. Happy to have 11 usable cogs for each ring )

Great hub for use on my Zipp wheels
rating
by JeffDers

Sammamish, WA

I recently purchased a new TT bike (Cervelo P3 Ultegra setup), and as it was a 2014 model, it came with 11 speed components. I use a pair of Zipp 808 wheels for racing, but they were still outfitted with my old 9-speed dura-ace cassette. What I did was purchase this cassette from WBW and also ordered a new hub to convert my Zipp wheels from 910 speed to accept an 11 speed cassette and had my local bike shop install them. It was pretty easy and I think this cassette performs just as well as the dura-ace one I replaced.

Need more speed
rating

My current bike came with a climbing cassette and i live in a place of flats. So there was no need for that cassette. So i decided to go for smaller gears for more speed. I love it, best upgrade i have done on the bike and it was pretty affordable.

I've used these cassettes for decades and they have never let me down. The 11 speed cassette continues to provide reliable shifts with a wider gear range, so that I don't need as many cassettes.

With short but steep hills around driftless region you need all the cogs you can get for 18 degrees. 11-32 does the job.

If you're putting on lots of miles, its hard to spend the extra on dura-ace. The performance of this cassette is on par at a fraction of the price.
