ShimanoUltegra CS-6800 11-Speed Cassette(Return to Product Page)

I've used these cassettes for decades and they have never let me down. The 11 speed cassette continues to provide reliable shifts with a wider gear range, so that I don't need as many cassettes.

Replaced the 11-28 tooth Ultegra cassette with this 11-23 tooth version. Quick and easy change, shifts flawlessly and provides ideal gear ratios for the southern Utah roads. Bike Tires Direct had the best price on the internet.

great price and you would be foolish to pay more. sure its a few grams heavier than top of the line. if your worried about that put down the doughnut !

Using this on my gravel rig......didn't need Dura Ace and am running it with Sram Force 22 drivetrain...works perfectly

With short but steep hills around driftless region you need all the cogs you can get for 18 degrees. 11-32 does the job.

Replaced an friends 11-25 cassette with this one 11-28. Smooth shitfing and climbing made a little easier !

If you're putting on lots of miles, its hard to spend the extra on dura-ace. The performance of this cassette is on par at a fraction of the price.

I love Ultegra. Almost all the benefits of Dura Ace, except weight, and much more affordable. And you have the illusion of being just a little better than 105 and with a Di2 option to boot. I am an intermediate rider at best and if I want a lighter, more aero bike, I can accomplish that by dropping 10 or 15 pounds of fat. At 205 pounds I love going uphill because of the thrill of going back down and passing the guys who drop me on the flats. But I'm working on that. The 11-32T option helps me both ways. Quality product at an affordable price at Bike Tires Direct.

upgraded my 6700 group set to 11 spd. can't go wrong with upgraded parts. I thought my bike shifted smooth, but now its a different machine.

I have been using 6800's for years, long lasting and smooth shifting

Gone are the days where one(non-pro paying out of pocket) might be tempted to jump on the Dura Ace train. Ultegra cost to benefit os better than ever over Dura Ace. And this applies more than ever to cassete purchases. These 11 speed cassetes are super smooth and will squash any delusions of trying Dura Ace. Biketiresdirect os an excellt outfit to do your purchasing.

Building wheels is the best thing about bikes. Using Ultegra 32 hole hubs and slipping on an 11 speed cassette when the wheels are done is a sure sign the wheels are going to do great things.

Nice new easy to install

Got the 32T and it's a great for hill climbing on road bike...

Excellent priced product!

great smooth shifting...I have always had the 11-28 the last year I have been using 11-32 and will never go back...I don't use the 32 that much but after a long ride and the last hill home it's great to know you have that extra gear if you are outta gas!

I have been using Shimano Ultegra for 15 years and have complete confidence in the quality. A good value as well.

I live in a very hilly area, and need a 32 on the back. Would prefer a d-Ace, but it's not made. Just a 30, sooo...

I mean what can anyone say about a Shimano Ultegra 6800 cassette. They work pretty great.

I already owned an 11-32 and 11-28. I wasn't too thrilled with them for some of my super flat crits around Chicago.

So I picked up the 11-25 and couldn't be happier. With these three cassettes I feel like I have the right tools to get the job done.

11-25 is going to be great if you want to race without to much elevation change. With the tighter spacing you can shift and find your sweet spot when you are trying to hang in the peloton and waste the minimum energy.

11-28 is going to be a great all around cassette. If you aren't going to be tackling steep grades. But won't be racing either. I don't think you could go wrong with an 11-28.

11-32 is great when you get those steep grades. Couple the 11-32 with a compact crank, you will be get getting up that hill!

Other than performance the Ultegra set is a great value for the performance it delivers. If your bike is properly tuned you can expect the components to last while delivering smooth consistent performance.

Already had an 11-32 this was too wide a range for my riding thus I bought an 11-28 for daily use and the 11-32 became my spare! Great products, hard to beat shifting!
