Ultegra CS-R8000 Cassette

Shimano's Ultegra group is one of the most popular out there with good reason: it's the perennial favorite when you factor the performance-to-dollars equation. With different demands for drivetrain ranges required for road, gravel, and CX riding, Shimano has created cassette ranges designed to allow the R8000 drivetrain to easily satisfy the needs for a variety of riders. The Ultegra CS-R8000 Cassette ranges as high as 32t, so you can set up the new Ultegra (or Dura-Ace R9100) with the range you need for gravel epics, 4 corner crits, hill climbs, junior nationals, and everything in-between.

Shimano's experience in forging, machining, and engineering allows for an enormous amount of technology that goes into tooth design, shaping, and shifting ramps. The cogs themselves are constructed from a nickel-plated steel that prevents corrosion and is slow to wear. Ultimately, this leads to cassettes that shift smoother and more precisely—and last longer—at a price that's friendly to the self-sponsored racer.

The top five cogs are grouped as three and two, respectively, and are riveted to anodized aluminum spiders that add stiffness to improve shifting. The remaining six cogs are individual with spacers between, and an anodized aluminum lockring screws into the freehub to hold the entire assembly together. One spline of the cassette is wider than the others and corresponds with the splines on the freehub, so the cassette cogs can only be installed with the right clocking of the shifting ramps, timing them for perfect chain pick-up and release. This innovation is true to Shimano's Japanese culture, which uses the term "poka-yoke" to refer to features—like these guiding splines—that serve as built-in wards against user error.

  • Long-lasting racing cogs for the self-sponsored cyclist
  • Reliable, durable steel preforms like Dura-Ace plus a few grams
  • Precisely machined ramps allow for accurate 11-speed shifting
  • Ranges available for crits to climbs to gravel grinds
  • Shimano's Ultegra R8000 drivetrain leads the way for best value in the industry
  • Item #SHI00FZ

I've been running same cassette for 10 speed, 11×33, and NEVER A PROBLEM. Probably 25,000 miles on the old one and looking forward to the same with this one, on new Pinarello Prince. Never had a problem with any Shimano product and all products are both mechanic and user friendly!

The ultegra cassette is the sweet spot in the price/weight/durability spectrum of shimano (and other brands) cassettes. My go-to for training and racing. I ride about 8k miles/year

Still the best

High quality, light, easy to install, good price, smooth shifting and comes in a wide range of tooth options. I use the integra cassettes on both my ultegra and 105 rigged bikes; bought this one for a gravel rig I am building. No complaints ever.

All cassettes wear out, and Ultegra cogs are a great replacement for the high priced Dura Ace OE gear at a slight weight penalty. Big thing is Competitive Cyclist shipped the right part very fast... Smooth running for this weekends rides!

My whole drivetrain is Ultegra. This cassette went on easily and it's great having a larger gear for climbing Utah's canyons. I ratios are still great for downhill and flats. Get one

Ultegra is long wearing and use it with an Ultegra chain. Runs smoothly. I've never had one break on me. If anything, they wear out over time as any metal parts wear out.

Can't go wrong with this

Familiarity:
I've put it through the wringer

I use these cassettes on both my Ultegra and Dura Ace equipped bikes. Yes, the Dura Ace cassette is lighter but after breaking two DA cassettes I've decided that there is nothing fast about "broken". I'm not a huge power rider either, I just think the DA cassettes are under-built to achieve their lightness. Sure pros use them but they are getting new cassettes put on constantly. So, save yourself some money and get this Ultegra-level cassette which will shift great and not leave you stranded.

Great Value for Ultegra 11-32T

Familiarity:
I've used it several times

Half the price offered by my LBS. Hopefully lasts longer than first. So hope to see same value when in need of new change in 5-6 months.

This is the official OLD MAN cassette

Familiarity:
I've used it several times

The basics: the cassette shifts nicely, like I expect from Shimano. The obvious trade-off from a 27 or 28 is the spread between various gears. The huge upside for my old arse is the lower end, climbing a 10% or whatever grade. Going from a 28 will likely only require adjusting the derailleur stop screw.

As Advertised

Familiarity:
I've used it once or twice and have initial impressions

I love how Competitive Cyclist always has quality components and clothing at competitive prices. Though I should have pulled the trigger a week prior because it was even less, I still felt that I received the best deal at the time from all of their competitors. This cassette will be a match for my new Enve 3.4 disc wheels, to match my current stock wheel/cassette combo.

Works great, training & racing (11-25)

Familiarity:
I've put it through the wringer

Bought two, to have one on the indoor trainer rear wheel and, one for road rides rear wheel setup. Hard to beat for the price and the mid level weight, compared to dura-ace or Sram XD at three times the cost for only 50-70 grams less, save those for race day! Can usually get 2-3 chains worth of life out of one rear cassette and set of front chain rings, then again, I clean my drive line after every ride and lube it, makes a huge difference in life of chain, gears, and how bike shifts.

Great

I have these combined with Shimano Ultegra SM-RT800 Disc Rotor on my Reynolds 58/62 Carbon Disc Wheelset and appreciate the performance when all combined.

Ultergra FTW

Super durable, fairly lightweight, and a bunch of ratios. This cassette always gets the nod when I'm in need.

Ultegra never disappoints

Smooth cassette at a nice weight. It's nice it comes in a 11-30. Nice bang for the buck too!

>Rating: 5

smooth as butter

Familiarity:

Smooth precise shifting. Purchased 11-25 to replace 11-21 for middle-gear range benefits. Ultegra - highest quality cassette with probably a little more durability than Dura Ace. (Obviously, a little heavier)

Shimano cassette

This cassette is very light and works great with my r8000 derailleur. I'm running a 11-28 cassette with a 50/34 crank.

Light, Durable and Quiet

Familiarity:

Perfect cassette for the money. Running 11-28 with SRAM Etap and DuraAce Chain. Crisp, precise shifting and seems to run a tad quieter than its 6800 counterpart.

Weight Savings!

Familiarity:
I've put it through the wringer

I upgraded my 105 5800 to the new Ultegra R8000, and purchased the 11-28 cassette to match my new short cage derailleur. Coming from an 11-32 105 cassette, this upgrade to Ultegra earned me a 60 gram savings! Ultegra 11-28 cassette weighed 246 grams on my PT scale.

Finally... a 32!

Familiarity:
I've used it several times

I gave this cassette as a gift to a family member who was really looking for a little bit more to help climb the canyons around us. Installing is the same as all Shimano cassettes, and the shifting is smooth and crisp! She is extremely happy knowing that she can run the R8000 cassette with her existing 6800, and is now able to go climb the roads just in time for fall. If you have any questions on the new R8000 gear, please reach out to me.

I currently have a 10speed shimano Tiagra on my 2021 TCR. Would i be able to use this cassette?

I'm currently running an Ultegra 11-30 cassette. Will changing it to an 11-32 require re-indexing the derailer?

Yes.

I have Sram force 22 - 1x11. Shifter/rear derailleur is Sram Cassette is Sram 11-32 one a wheelset. can I swap a Shimano 11 speed cassette 11-32 on another wheelset without any problems??

Hey Mike! As long as your chain hasn't stretched out to match the profile of the SRAM cassette, you should be able to move over to a Shimano cassette without a problem. I've included a link to a great chain checker below. Thanks! https://www.competitivecyclist.com/park-tool-chain-checker?skidn=PAR002X-ONECOL-ONESIZ&ti=U2VhcmNoIFJlc3VsdHM6Y2hhaW4gY2hlY2tlcjoxOjE6Y2hhaW4gY2hlY2tlcg==

Just purchased new carbon wheel sets from CompCyclist....can this Ultegra CS-R8000 11x32 & Ultegra CS-HG800 11x34 cassette competable with my new 105 11 speed group set ? Wanting to replace and/or upgrade 105 CS-R7000 11x32 cassette with this?

Go for it. It's a good component. Good durability and mid weight range.

>Rating:

I have a 6800 11-28 cassette on my wheel. Can I use this 8000 11-28 cassette on a spare wheel for my trainer and not have to fuss with adjusting the derailleur?

With same question in mind, I bought r8000, actually couldn't find original cs6800 at least 1 year ago. Have no problem with original cs6800 outdoor, but some noise especially in one of mid gear (maybe fifth) while Zwift. Nowadays find a cs6800 casette and try to be sure, if it is real problem or anything else

A follow up question. Can a 11 30 cassette be used with a short cage 6800 Di2

No. 11-28 is the max range for the short cage

i currently run an 11-30 on my Di2. the cross chain can cause issue but i haven't had issue whine's paying attend to its been fine for over a year...... that being said its not recommended

For those with the newer ultegra R8000-SS rear mech in now fits up to 11-30t.

Shimano says no. But I have been running one for a year now with 36-52 up front. Maybe 39-53 might b diff. Never tried that combo.

this cassette also works with the ultegra 6800?

>Rating:

I need to replace my 11-28 6800 cassette and chain. Is the R8000 compatible

Absolutely. R8000 cassette and chain are compatible with the older Ultegra 6800 groupset. Please let me know if you have any further questions. igonder@backcountry.com or direct line 801-619-7476
