ShimanoUltegra CS-6800 11-Speed Cassette(Return to Product Page)

Flawless shifting, a little more weight than Dura Ace, but otherwise, no noticeable difference.

This is a great cassette that will stand up to abuse and keep delivering day after day. I use these cassettes on my road and cyclocross bike and they stand up to everything.

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.

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.

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 )

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.

Just what I neededwanted, I was unable to find the 1123 cogsetanywhere bad bar, Performance and the like, Plus it was a great deal better price than any other place also

This is a mainstay of my arsenal

trek madone. works great.

I use this on this on my bike

A perfect mix of a speed and climbing gears

Quality product priced appropriately

This cassette has been a reliable and great component. You will not regret purchasing this from Western Bike Works

Great climbing gear. More quiet than sram

Way less in price vs dura ace

great price and you would be foolish to pay more. sure its a few grams heavier than top of the line. if your worried about that put down the doughnut !

Using this on my gravel rig......didn't need Dura Ace and am running it with Sram Force 22 drivetrain...works perfectly

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

My 2021 Emonda Project One came with climbing wheels and gears that work great all around. But for flat Florida cruising I put this 11/28 cassette on my Elemental wheels for precise cadence control.

upgraded my 6700 group set to 11 spd. can't go wrong with upgraded parts. I thought my bike shifted smooth, but now its a different machine.

The cassette is as you would expect for Shimano Ultegra - solid, reasonably light weight, with no problems at all.
