    Save where it matters, not where it doesn’t.

    If you’re putting together a workhorse group, going sub-primo on the cassette makes a lot of sense. It’s the first part that’ll wear out if you’re logging serious miles, and since it sits at the center of the wheel, its effect on rotational weight is quite low. Shimano’s Ultegra 6800 Cassette consists of 11 steel cogs riveted onto an aluminum carrier that’ll help reduce wear on your freehub body, and comes in a wide variety of gear options, from a corncob-like 11-23 to a spin-to-win 11-32.

    • 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

    All-Around great

    • Familiarity: I've put it through the wringer

    Reliable, dependable, long lasting. Ultegra is like a Toyota Camry, it isn't flashy, but it works every time. Light enough, and cost effective for any build, hard to overlook it for a performance oriented road build, especially if you are on a budget. Great cassette for the money. Hard to beat.

    Can't go wrong.

    • Familiarity: I've put it through the wringer

    Can't go wrong with an Ultegra cassette; only weighs 15g more than a comparable Dura Ace cassette, but is a quarter the cost. Sorry; I can't justify $150 for 15g savings, except maybe on race-specific carbon climbing wheels.

    Gets the job done

    • Familiarity: I've put it through the wringer

    As far as cassettes go, there isn't a lot to review but the Ultegra cassette is a solid. lightweight and durable choice for all riders. Not quite as lightweight as the Dura ace version but the ultegra when paired with a new chain offers for buttery smooth shifters and a killer ride. I meticulously clean my chain and cassette and they have lasted me about a year usually.

    Always In Need

    • Familiarity: I've put it through the wringer

    It's easier to have more than one cassette, as to not have to constantly change them between wheels. Ultegra level cassettes don't have the lightweight pedigree of Dura Ace, but pricing vs. weight/performance is good enough. Durable and easy to maintain.

    Works Everytime

    • Familiarity: I've put it through the wringer

    Have used used these on multiple bikes with the same conclusion- works great every time. A good alternative to Dura Ace, as these are consumable items and a better value with good weight comparisons. Currently have is installed on my Dura Ace Di2 and integrates perfectly.


    • Familiarity: I've put it through the wringer

    Shimano Ultegra is just a great all around group. I have seen it equipped on professional team bikes (smaller US teams, but they are getting paid to ride) If I had to make a choice between running Dura-Ace and mediocre wheels, or running Ultegra and amazing wheels, I would run Ultegra for sure.

    With the Cassette, I opted for the 11-32 cassette for the mountainous terrain found here in Utah. I love spending time in the hills, but I am by no means a great climber. For the 11-32 cassette you do need to run Shimano's mid cage rear derailleur. It is hard to beat the reliability, quality, and acceptable weights that are offered by Shimano's Ultegra group.

    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.


    • 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.


      • 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.

      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!

      Will the 11-32 work with my Shimano Ultegra Di2, 6870, 11-speed rear derailleur, or do I need one of those extended derailleurs like you used to need for the 11-32?

      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)...

      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

      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.

      Can you use the 11-32t cassette with the short cage derailleur?

      Best Answer


      No, you would need the Mid/Long cage derailleur if you wanted to use the 11-32t cassette. The short cage is designed to only have enough chain wrap for a 28t or less cassette.

      i use an 11-32 with a short, however, you CANNOT cross chain in your big ring (to your 32).

      i have no problems with my small ring to my 32.

      i only have this setup on my training wheels, and pay strict attention so that i do not cross chain.

      if i have to be in my 32 i should be in my small ring anyways.

      it is not the ideal setup, however it does work - you might have to adjust your b-screw.

      I have Shimano Ultegra 6800 11-speed short cage on my 2015 CAAD 10. I have the 11-32 cassette on my CK/HED climbing wheels and it works like a dream. A fellow rider has been running this CR-Cassette combo for three years with NO PROBLEM. I just don't use large CR to 32.

      Can the CS-6800 be used on the Shimano version of the PowerTap G3? I'm using this hub with CS-6600 right now.

      Best Answer

      greetings - You should be good to go :) See the link to the actual PowerTap website for that tasty hub. Good day :)


      Unfortunately, I found that the CS-6800 doesn't fit my Shimano PowerTap G3. I'm trying to buy a replacement 11-speed freewheel body for it. My understanding is that this freewheel body will not require re-dishing my wheel and will allow me to mount the CS-6800 ... and therefore upgrade to Ultegra 6800 throughput.

      Maybe DRZIPGRIP is thinking of newer versions of the G3 hub, but mine certainly does not accommodate this cassette.

      Mike, I just replaced the freehub body in my G3 with the 11 speed version and it is a piece of cake. It will allow you to run a 10 speed cassette (with a spacer) and the 11 speed cassette without. It just pulls right out of the hub and you slide the new one in.

      Sorry, amateur question, can the 6800 be dropped in place of an existing 10sp 6700 gear set, or does the full set need to be upgraded as well?

      Best Answer

      Additionally, wheel manufactures are still catching up to the 11-speed. Currently the Shimano 9000 line of wheels with work, also, Most Mavic wheels will work with 11-speed, even some older models. New Zipp's will work. Just make sure that the wheelset you are using is compatible - hope it is :)

      The distance that each click of your shifter moves the derailleur in relation to the spacing and position of the cassette's gear determines whether or not the chain remains on any given gear. If your shifters have 10 click-positions and the cassette has 11 gears, you'll either eliminate the ability for the chain to reach one of the gears or prevent your chain from dropping smoothly onto the corresponding cassette teeth.... Short answer:

      10sp shifter=10sp cassette/chain & 11sp shifter=11sp cassette/chain
