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

My current bike came with a climbing cassette and i live in a place of flats. So there was no need for that cassette. So i decided to go for smaller gears for more speed. I love it, best upgrade i have done on the bike and it was pretty affordable.

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.

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

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 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!

Good price for what you get

If you're on a budget for a cassette, look no further. Ultegra has always been the sweet spot for performance orientated parts from Shimano. I can purchase a 3 sets of cassettes for the price of a Dura Ace.

Great shifting with the Ultegra R8000

Smooth shifting. Great range for climbing. Heavier then Dura-Ace but much less expensive.
