Shimano knew that the Ultegra 6800 cassette would reside as the heart of the new 11-speed system, which is why it devoted considerable time on a feature known as 'rider-tuning.' What this means is that you receive an updated range of useable gearing options with the advent of the 11-speed design.

It also means that, even if you're running Dura-Ace, you can pop on an Ultegra cassette and no one will ever know. Except you. But once all the blood has abandoned your head for your legs, you won't care—and the fact that it's all steel instead of partially titanium means it'll last longer, too. There is the issue of weight gain compared to Dura-Ace, but since the cassette inhabits the center of the wheel, it plays no role in the inertial mass at the wheel's diameter, so it won't hamper spin-up.

Cassette options with Ultegra 6800 now range from 11-23t to its climber-friendly 11-32t. The additional cog in the back means the new cassette runs straight through for a bit longer, which generally means the addition of an 18T cog over the 10-speed. This smoother run of gearing is most noticeable while spinning in the top end of the block, allowing more consistency and control over your cadence compared to 10-speed cassettes.

Shimano Ultegra CS-6800 Cassette is slightly lighter than its 6700 brother, and it does a nice job of closing the gap on Dura-Ace 9000. The tallest cogs are riveted onto an aluminum carrier for weight savings, and they're gentler on aluminum cassette bodies. Shimano improved its manufacturing quality too; now they can make the ramps stronger because they can build to tighter tolerances. And the ramps themselves have been revised for faster shifting.

  • The cassette of choice for self-sponsored racers
  • Reliable, durable steel outlasts more expensive Ti options
  • Precisely machined ramps for Shimano 11-speed shifting
  • Shimano's Ultegra 6800 drivetrain may be the best value for racing in the industry

Great for Road or Cross

  • Familiarity: I've put it through the wringer

I use the Ultegra 6800 cassettes on my road and cyclocross bikes and I've been very happy with the shifting performance and durability. Even during some muddy CX races my bike was shifting fine.

Carves the Road

  • Familiarity: I've used it several times

I use this cassette on my mechanical Dura Ace equipped bike. Using it is definitely a more cost-effective alternative to training on (and wearing out) Dura Ace cassettes, at 3x the price. I just wish Shimano made the Ultegra in a 12-28 option.

A classic

  • Familiarity: I've put it through the wringer

Just moved to Utah from Indiana and I immediately swapped out my 11x25 with a short cage for the 11x32 with a long cage on my gravel bike. I can now make it up all of the steep gravel pitches in the mountains with enough energy to look around and enjoy the views.

This cassette is the best on the market for the price and weight, not to mention it's durability. As a recent college grad trying to buy new bike parts can be expensive! At least with this cassette it didn't break my bank account and I know I will get my moneys worth.

All around Cassette

  • Familiarity: I've put it through the wringer

I pair this with my 53-39 and that's all I needed. You can go up very hill and mountain and you can speed downhill too.

Sweet

  • Familiarity: I've put it through the wringer

I bought the 6800 package, cassette, derailleur and chain. The gearing spread combined with a compact 50-34 is wonderful, especially if you live in mountainous country. Shifting is flawless and smooth. 6800 is more durable and cost effective then the Dura Ace cassette.

11-32 Climbs like a Goat

  • Familiarity: I've put it through the wringer

I switched out my 11-28 and short cage for the 11-32 and the long cage after running out of gears on too many climbs. Making the switch was one of the best things I've done to my bike, as I've never had problems on steeper climbs. Second only to losing weight, this is one of the best things to do to become a better climber.

More cost effective than dura ace

    I have a dura ace cassette on my race wheels but end up training on my ultegra cassettes. At the rate that i go through cassettes, this is far more cost effective. Its a little heavier for sure, but i'd be lying if i told you that i could tell that the dura ace cassette shifts better.

    Standard

    • Familiarity: I've put it through the wringer

    The Ultegra 6800 cassette is a thing of beauty that gets beat up and abused more than anything else on your drive train. It gets forgotten in the back because when everything else works, you don't need to worry about the cassette. Wipe it down when you clean your chain and replace as needed based on wear.

    I currently run a 105 52/36 set up up front and a 12/30 in the rear cassette Ultegra. Would there be issues if I run the 11/32? I already have a longer cage (Ultegra)...

    Just a slightly easier climbing gear. No issue as long as your 12/30 is 11-speed.

    Shouldn't be a problem if you have the long cage.

    Great cassette. Wouldn´t pay for DuraAce

    • Familiarity: I've used it several times

    This cassettes has everything you want for training or racing: lighweight, gear ratio configurations available and great durability. Take basic care and this will last for hundreds of miles.
    CC keep the great prices on Shimano Ultegra components!

    Great cassette for any 11 Speed setup

    • Familiarity: I've put it through the wringer

    I built up a SRAM Force/Rival/Red setup for my commuter and used the ultegra cassette and chain for the package and the thing shifts perfectly. The ultegra cassettes seem to last me about 3-4 chains. Each chain replaced at around 1500 miles or when it reaches just over .5%.
    I am using a red crank, Force 22 shifters, force 22 FD, and Rival 22 RD.

    Also worth the weight!

      Like all of the Ultegra 6800 group parts, the Ultegra cassette works flawlessly, won't make you have to skip a mortgage payment and will cost about 40grams. The way I see it, unless you're getting a paycheck for pedaling your bike you'll sweat off the 40 grams while enjoying the super-smooth, predictable shifting this cassette provides!

      SHIMANO has done it once again

      • Familiarity: I've put it through the wringer

      This cassette is fantastic. Shifting is effortless, like slicing warm butter. Each gear hits right on the mark even with tension out of the seat climbing, no miss shifts.

      I upgraded my 8 speed drive train with a triple up front to the whole 6800 group set... Love SHIMANO

      Best road cassette for the money

      • Familiarity: I've used it several times

      The Ultegra is the best cassette out there for the money. I replaced the 12-25 that came on my new bike because I do a lot of climbing and needed some easier gears to spin. I first used this for a century ride in which I climbed nearly 7,000 feet and I didn't miss a shift. Love it!

      The best cassette

      • Familiarity: I've put it through the wringer

      I'm running this with my DA9000 setup and it works flawlessly. Why not run a DA you ask? well I don't like spending that much more money to save a couple grams and the ultegra just last way longer.

      White Collar Conduct, Blue Collar Wage

      • Familiarity: I've put it through the wringer

      While not as light as Dura Ace, the Ultegra cassette offers smooth shifting and long durability at a reasonable price tag. Unless you are counting every gram or have a Dura Ace tattoo somewhere on your body, your cassette search ends here.

      I have dura ace di2 with a 11/28 cassette and 52/36 up front...its hard on long big climbs, can i change the cassette for this 11/32? is it compatible? will i sacrifice the quality of the durance di2?

      If you have the dura ace di2 RD-9070 rear derailleur, unfortunately no. You need a medium cage rear derailleur to use the 11/32 cassette. I'd recommend considering switching to a compact crank instead - like the FC-9000 50/34

      Best Answer

      There is a work around, flip the b-tension screw and you can go up to 32. Ssshhh don't tell shimano.

      Many may steer you away from 11/32 but the fact is: Several great cyclists I ride with run 11/32 with the intentions of training on long, steep, big climbs. I am not familiar with di2 R-Der. but on my D-A and on my Ultegra (both mechanical) there is enough adjustability to use this cassette without fear of "breaking" anything. I just added a link to my chain and I avoid cross-chaining to the 32-tooth gear. . . Ask some average-sized climbers (not the 116 lb toothpick-armed pro-climbing-specialists who can ascend Mt. Baldy at 26 kmh) and you'll see an extra tooth (or two) is A GOOD THING.

      I'm not sure about Di2, but I have some experience with using a D/A 9000 mechanical RD and an Ultegra 11-32 cassette on a 2016 Ridley Fenix SL frame.....with some b-limit adjustment, the combo worked fine. That is, however, until one day I accidentally shifted into the large chainring at the top of a mountain while still in the 32t cog. I was actually shifting both at the same time, but apparently shifted the front slightly faster......and the drivetrain immediately locked up and basically broke my RD. It would still function to change gears, but I couldn't shift into the large chainring without the RD shooting forward and the chain skipping around the outside of the pin next to the bottom pulley on the RD. It was a lot of fun trying to get the chain out of the 50/32 combo - lots of brute force and ignorance required. I was able to finish my ride (56 miles and 6,000 feet of climbing) in the small chainring, and thank God was able to still shift in back.....but I promptly went down to the bike shop and got an Ultegra long cage RD, and it works like a champ now. With the D/A 9000 mech shifters, the Ultegra RD even almost feels like a D/A RD (I have full Ultegra 6800 on my gravel bike, and while it's good, doesn't feel as smooth as my D/A 9000 stuff). Moral of the story is, use a long cage in back if you're running an 11-32. Sure, you can get away with a short cage, and I did for quite some time....but I certainly wouldn't do it again.

      IT WORKS!

      • Familiarity: I've used it several times

      No big shocker, but it works! Had to upgrade from a 10 speed freehub body on this older wheelset when I got the 105 5800 group. Works like it's always been this way, good cassette!

      IT WORKS!
