Having an 11 28t cassette on my trek street bike U found it cumbersome going up steep hills. The 11 30t cassette eased my efforts. I called with questions and was completely satisfied with the expertise i was given. Very happy with my experience.

Almost seamless
by Tuabui
Charlotte NC

I currently use the Ultegra CS5800 11 speed group set. Actually, this group set comes with the 105 11 speed cassette. My goal was to be able to switch out seamlessly with my current wheels so when I had a chance to buy a similar brand wheel sets but deeper, I bought the CS-R8000 cassette. The installation was simple but you will need a proper torque wrench to fit the Shimano cassette to the proper spec. You may need to adjust the brake pads to make sure there is no rubbing. I did not have to adjust the rear derailleur as the shifting was dead on. The sound coming from the new cassette as the shifting takes place was loud and crisp. The sound level is still crisp but less noticeable as the teeth began to wear and sits precisely on the chain. It feels great riding with a new cassette. I may have eliminated a few grams compared to the 105 cassette. I have put in 200 miles so far and enjoying the new cassette and deep wheels.

Was just going to buy a 105 cassette fit direct drive trainer, but the sale price of this was cheaper. As expected, great, crisp shifts, no skips and very smooth.

Highly recommend.

32t is just that little extra
by GDS PDX
Cycling Enthusiast

0 of 1 customers found this review helpful.

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.

Handles anything thrown its way
by Superdupersix

Relatively quiet, though a bit heavier. Never had a mis shift, just does as asked. Last ride was a huge climb, 4,500ft elevation in 13mi, no complaints.

Consistent, effective
by Timberwolve17

With most cycling parts, it's about will it make me faster?

I purchased this cassette for a second wheelset. The cassette did not make me faster, but it did let me use my new wheels. Perviously my groupset was shimano 105, and I did not notice any significant differences upgrading to Ultegra.

Would I buy this again? Yes, but only because Dura Ace is such a dramatic jump up in price

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

Much better than 6800

Every 8-10k miles or once a year and every other Dura-Ace chain, I get a new cassette. This new 8000 series makes shifting smooth and reliable. It's easy to clean and to install.

Nothing overly special. It's a cassette that works well. Shifting is smooth and cassette is quiet in operation. I am using a KMC X11SL chain with no problems. I've had Dura-Ace cassettes and from a functionality standpoint there is no difference with the Ultegra cassettes.
