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.

  • Nickel-plated steel cogs
  • Optimized gear ratios

Work horse

    THe 105's last forever! Sure they are a bit heavier but i don't care as it is on my commuting bike. Love Shimonos products. High quality, smooth and keeps you spinning all day long!

      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.

      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

      105 = Awesome

      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.

      Solid

      • 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.

      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.

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

      An 11 speed cassette will not be compatible with a 9/10 speed splined hub. You will need to find the correct 11 speed freehub body to convert your wheelset first. Call to speak with one of our bike experts to get your new 11-speed drivetrain dialed in!

      Unanswered Question

      Hello
      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?
      Thanks.

      cheap and awesome

      • Familiarity: I've put it through the wringer

      I run this cassette cause it's the same thing as the dura ace, just weight difference which doesn't matter to me anyway. Keep spinning the wheels and you'll be fine.

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

      32 tooth works fine on my 2015 CAAD 10 with short-cage Ultegra 11-speed derailleur. I run 50/34 Praxis/Zayante CR's. Great for steep climbing!

      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 robsmallman@backcountry.com and I can help.

      Can you tell me if the cassette is black or sliver.

      The cassette is silver. Please let us know if there's anything else we can help you with.

      can this be used with the 105 10 speed deraileur?

      Unfortunately this cannot be used with a 10 speed derailleur. This particular cassette is 11 speed only. Item # SHI0634 is the shimano 105 10 speed cassette.

      Does anyone have a weight for these...
