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

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...!

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

I use this cassette on my Specialized S-Works and it shifts great and lasts along time. I. am replacing a similar product which provided me 30,000 miles over the last 4 years.

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

Best for uphill.

Shimano Ultegra is installed on all my bikes. Never fails me.

Just updated my Trek Madone with this wider range cassette. It is perfect!

This cassette works like a dream. Smooth shifting and I always seem to have the gear I need. Nice!

This cassette makes my rides more enjoyable, I expect it to last a long time given Shimanos reputation.
