ShimanoUltegra CS-R8000 11 Speed Cassette(Return to Product Page)

Quality cassette at a great price! I'm running a standard crank with the 11-30 cassette and love it! I could do 11-32 so I could spin more but not complaining here!

The new CS-R8000 cassette benefits from trickle-down technology from the DuraAce group as the lowest (largest) five gears are affixed with spiders which makes the spacing between gears more accurate and shifting becomes even smoother than in previous versions of Ultegra cassettes.The only penalty is a slight increase in weight versus the DuraAce version. It is certainly a bargain, especially if it's on sale at BTD.

Kudos to Shimano for creating a very affordable high performing cassette. Shits up and down super smooth. No need for dura ace if you have this (unless youre a weight weenie).

Very quick delivery and a great price. No problems encountered.

100% roadie who isn't afraid of the dirt/water/and other perfect road conditions approves this cassette for all your cycling needs!

Shimano ultegra is the best without the high price

Simply the best bang for your money. Dura Ace weight savings not worth the price difference.

Compared to 105, this cassette is lighter and offers smoother shifting. Very happy and I got a great deal. BTD shipped super fast!

Cassette 11-30 used with Durace di2 9000.

The cassette shifts great. Just a little heavy. But is a great price. And yes, the 30 tooth cog works!

No problems.

Solid cassette at a great price. Installed on a new wheelset. Shifting is smooth and precise. Does everything it is designed to do well.

Needed to replace the cassette on my 2017 Cannondale SuperSix Ultegra Disc so I chose this cassette, which was a close equivalent to the original. Shifting is flawless in combination with a new chain and shifter cable.

I got a set of climbing specific wheels and wanted a cassette that would leverage that even further. The 32-11 was a good call. I really don't use the 32 that often (most climbs are fine with the 30) but when you hit a wall and need just a little more leverage and a little more confidence, the 32 is nice to have. I was worried about chain length because my other wheelset has a 30-11, but I have had no problem. If I was moving from a 28 to a 32, I'd probably need an extra link or two, but the 30-32 switch has performed fine on an Ultergra Di2 longcage derailleur.

Fit great and easy to install. No real adjustment necessary.

Like a staple in your diet! Always required! Always reliable. Ultegra is always there...!

I LOVE THE CASSETTE AND SHIMANO HAS BEEN EXCELLENT DRIVE TRAIN FOR ME SINCE 1986

We have a lot of steep hills in my riding area. This cassette with its lower gear helps my climb those 15 and 16 percent grades
