    11 speeds to heaven.

    Sure, new Shimano's CS-5800 has 11 nickel-plated steel cogs to give you extra gearing options, but all the gears in the world aren't much good if you can't shift smoothly between them. Shimano optimized the ratios between each and every cog to provide smooth shifting and make sure that your cadence increases or decreases by equal amounts, regardless if you're shifting between the two biggest cogs or the two smallest. No jumps between gears means smooth, easy pedaling, which equals less fatigue and fewer losses of momentum, so those tough hills will float by a little bit easier than they used to.

    Training cassette for training wheels

    • Familiarity: I've put it through the wringer

    There are times when it makes sense to buy top-of-the-line product and time when it doesn't.

    Obviously, if you're on a budget, the cassette is one of the places you can scale back, there'll be a little bit of a weight penalty, but in shift quality, it's going to be the same as any of the upper end cassettes.

    Where it really doesn't make sense to buy the top-end stuff (whether you're on a budget or not) is on a dedicated training wheel, or when putting a cassette on a direct-drive trainer like the Wahoo KICKR Power. In that situation, save your money, buy the 105 cassette, and put the money you saved towards a nice pair of wheels, or a bottle or two of good single-malt whisky.

    Work horse

      The 105 line used to be a bit of a joke, heavy and obtuse. Now it is every bit as good as many other brands 2nd tier products, at a fraction of the price. Not super light, but really does the trick and shifts every bit as good as Ultegra. Go for it.

      105 = Awesome

      • Familiarity: I've used it several times

      I bought this cassette as part of a 105 groupset to put on a spare frame I had laying around. I decided to go with 105 because the 105 has had a history of being Shimano's workhorse group and this 11 speed group is priced great, which leaves money for wheels or cockpit parts. Every component within the group got a good upgrade and resembles features found on the higher priced 11 speed Dura-Ace and Ultegra groups. The 105 groupset also allows for a pretty easy gear configuration if you're interested too (11/32 cassette, long cage rear derailleur & a 50/34 crank). If you're on a budget or want a group for a training bike, the 105 11-speed group is no-brainer option.


      • Familiarity: I've put it through the wringer

      New 105 cassette is a solid option for you Shimano 11 speed drive train. Obviously not the light weight option of Dura Ace or Ultegra, been still a sleek and durable as it gets cassette. Great for your everyday riding wheel.

      Hidden economy.

      • Familiarity: I gave it as a gift but have feedback to share

      The new 105 stuff blows me away. And I'm a Campy-phile. It may be the best economy-to-performance groupset on the market today, so--even if you're splurging for Ultegra or Dura-Ace--you can mix it with the 105 cassette without worrying about any sacrifices outside of a few added grams.

      Unanswered Question

      My wife is riding a Kestrel Talon Road with a Shimano 105 11 speed Sun Race 11-28 cassette, she is purchasing a set of new wheels and was considering going to the 11-32 cassette to get the one more climbing gear. Is this a direct swap with no adjustment to the derailer and can we swap back and forth without adjustment. I have a chainwip/tool and have swapped cassettes before. Thanks

      Hello Again
      Will an 11 speed cassette fit on a 9/10 speed splined hub? Does anyone know the width of these cassettes?

      Unanswered Question

      I have a 9 speed 11-34 SRAM cassette and a XO SRAM derailleur. I wish to change this to a 10 speed set up. Chain, cassette and shifter have to be changed. Do I have to change the front and rear der.? The front der. is an ultegra. Will the chain rings work with the 10 speed chain?

      will the 32tooth option work with a standard Shimano Ultegra 11 speed derailleur?

      The description for Shimano 105 CS-5800 11-Speed Cassette 11/32 is that the color of the cassette is black. Is this true?

      Hello there,

      The colour of the cassette is silver. I'm not sure where black came from, but the cassette is most definitely silver. When buying a cassette with a 32 tooth cog, I have to ask if you have the appropriate length cage on your rear der to run that large of a gear. Email me at and I can help.


      can this be used with the 105 10 speed deraileur?
