Description

Ready for racing, this superb model is equipped with 11 steel sprockets which are more than capable of handling all the intensity that comes with all-day events. Using HG-EV technology, this version gives you a rider-tuned gear combination and cadence management. This means you'll benefit from its optimal gear ratio which perfectly suits your riding discipline, so you can blast up to speed in seconds and maintain the edge over your competitors.

Tech Tip: This cassette is compatible with all Shimano 11-speed road derailleurs. However, you should choose the same tooth count as your existing cassette or confirm the maximum cassette capacity for your derailleur before choosing)

Please Note: The 11-34T version of this cassette is the "CS-HG800" model as Shimano does not make the CS-R8000 in an 11-34T version.

Technologies:

HG-EV: HG-EV cassette sprocket is for rider-tuned gear combination & cadence management. We provide optimal 11-speed drivetrain gear ratio; you can choice wider and closer gear combination available to match various riding disciplines. HG-EV cassette sprocket is obtained 11-speed gear without compromising the 10-speed durability and improved HYPERGLIDE shifting.

HG-X11: Silky driving, accurate shifting. HG-X11 directional chain realises more smoother shifts and greater overall performance. Right and left sides are optimised for front and rear shifting respectively.

Customer Reviews

Shimano Ultegra R8000 11 Speed Cassette is rated 4.8 out of 5 by 115.
Rated 5 out of 5 by Mick613 from Smooth shifting Well made, smooth shifting and durable. Not as light as more expensive options, but not by much.

Rated 5 out of 5 by mshing from it works as you'd expect from Shimano. Ultegra version offered me the ratios i wanted and i prefer the satin look to the sprockets that are a cheap shiny finish on the 105. Slightly lighter with Ultegra compared to 105

Rated 5 out of 5 by ChrisP1975 from High quality cassette High quality, hard wearing cassette - a notable upgrade on the 105 version. Smooth shifting guaranteed

Rated 5 out of 5 by JamesB99 from Always a trusted buy Gone for a larger cassette as I am now running bigger Rotor chain rings. Helps me up those hills! Ultegra is a great product, light and durable without the hefty price tags

Q & A

Is this compatible with 11 speed 6800 ultegra .

We can confirm the Shimano Ultegra R8000 Cassette is indeed cross compatible with the older generation of the 6800 Ultegra series

will an 11-30 cassette work with a 6800 standar rear deraileur?

Asked by: sliab
I can advise this should be fine as it will be compatible with older generations of Shimano. I hope this helps.

Will the 11-34 be ok with a ultegra medium cage rear mech?

Asked by: DAVE654
Don't think so Dave - think you'll need the long cage e.g A road bike with Ultegra 6800 11 speed compact, 50-34, and a short cage derailleur. Which cassette is possible? 1. Maximum cassette size: The Ultegra 11 speed short cage has a maximum cassette size of 28t. A cassette with more than 28t is impossible Solution: mount a long cage derailleur, for example the Ultegra 6800 long cage, which has a maximum cassette capacity of 32t. 2. Maximum difference between the chainrings is 50-34=16t. This is within the range of a long cage. 3. Capacity of the drivetrain is (50-34)+(34-12)=38t. The short cage has a capacity of 34t, the long cage 40t. Conclusion: long cage

Is chain length affected?

I have a 2017 Specialized Roubaix Comp Ultegra 6800 with 11/32. I presume with this set up I have the long cage derailleur and I can see from previous answers that this cassette is compatible but would I need a new chain to accommodate the additional two teeth?
Asked by: CJST
there Is an online chain length calculator that I’ve seen recommended. Seems to work and is easy to use. Search for it, enter your two largest cogs, chain stay length. And it figures it out

Maximum 8000 series cassette size for Ultegra Di2 6870 GS?

I've just changed the cage on my Ultegra Di2 6870 to go from SS to GS as I was planning on switching from 11-28T to 11-32T. However, now that the 8000 series introduces 11-34T, I'm wondering if the Di2 6870 GS would support 11-34T?
Asked by: onebc
Shimano do only list the Di2 6870 GS rear derailleur as compatible with a cassette up to 32T so it would not be recommended to use this with the 11-34 cassette,

I got a Easyway Zener D1 from Wiggle 2 years ago. Will a 11-34 cassette fit with the Ultegra derailleur supplied with the bike as I'm not sure which size it is? Also will I need a longer chain?
Asked by: Obone
Unfortunately this would not be suitable. The largest cassette size that could be used is a 32t.
