Shimano Ultegra 6800 Cassette $109.95
Move up from 10.
Shimano knew that the Ultegra 6800 cassette would reside as the heart of the new 11-speed system, which is why it devoted considerable time on a feature known as 'rider-tuning.' What this means is that you receive an updated range of useable gearing options with the advent of the 11-speed design.
Cassette options with Ultegra 6800 now range from 11-23 to its climber-friendly 11-32. The additional cog in the back means the new cassette runs straight through for a bit longer, which generally means the addition of an 18T cog over the 10-speed. This smoother run of gearing is most noticeable while spinning in the top end of the block, allowing more consistency and control over your cadence compared to 10-speed cassettes.
Shimano Ultegra CS-6800 Cassette is slightly lighter than its 6700 brother, and it does a nice job of closing the gap on Dura-Ace 9000. The tallest cogs are riveted onto an aluminum carrier for weight savings, and they're gentler on aluminum cassette bodies. Shimano improved its manufacturing quality too; now they can make the ramps stronger because they can build to tighter tolerances. And the ramps themselves have been revised for faster shifting.
The Ultegra CS-6800 Cassette has 11 cogs and comes in the following ratios: 11-23T, 11-25T, 12-25T, 11-28T, and 11-32T. Each cassette wears a nice chrome finish and comes with an alloy lock ring. Please note that the CS-6800 is recommended to be paired with corresponding Ultegra 6800 components.

Can you use the 11-32t cassette with the short cage derailleur?
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.
Superb cassette and light :)

Always superb quality, weight is dead-on at 212gm for the 11/23. I also have a DuraAce 9000 and will use this one for flats and daily riding, putting the 11/28 9000 series on my climbing wheels. For those using Shimano cassettes and note that some freehub bodies are prone to indents from the DuraAce cassettes - using Ultegra cassetes will always solve that problem, as the titanium cogs on the DuraAce are just too hard. Sticking with the Ultegra, especially at this price, is a total no brainer. Shifting is solid and dead on, no skips or hesitations and quiet as can be :) Also noted that I have tried Zipp and Mavic wheels with both the Ultegra and DuraAce 11-speed cassettes and have not had any scoring/indents on the freehub bodies; even after 3000 miles. Looks like the newer 11-speed freehubs are hardened (at least for these two manufacturers) - so cheers to that!
Can the CS-6800 be used on the Shimano...
Can the CS-6800 be used on the Shimano version of the PowerTap G3? I'm using this hub with CS-6600 right now.
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.
It's a piece of cake if you have a compatible PowerTap hub; some PowerTaps can't accept the 11-speed body. (And, even if it does, it's about $90 to buy the new hub.)

Is this cassette compatible with Dura-Ace 9000?
Yes, this cassette is compatible with Dura-Ace 9000.

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?
I would think that you'd have to switch out the shifters for sure to get the 11th gear, but the rear derailleur is probably still ok from the 6700.
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 :)
