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

I like dealing with Biketiresdirect

Good service, quick shipping and great products all at a fair price

I stay with oem drivetrain components

Works well with Shimano or Sram drivetrains. Cheaper than Sram.

And again a shout out to the staff there in helping meselect the right components for my bike.

Ultegra seems to be the sweet spot between performance and value. This casette is a good deal and the 30 tooth option provides that one extra for a hilly area.

I had to reinstall it 4 times to finally get it shifting correctly. I am not sure what was wrong on the 3 failed attempts given each of the smaller cassettes should only fit a single position, but I wish Shimano would just make it a single piece.

Love these Shimano cassettes. They wear good and are smooth shifting. Get an extra for different gearing or an extra as these are a wear item.

Light, look awsome and function very well! Looking forward for many rides together.

I like the lighter weight, not a huge increase in price, and the 30 tooth option provides a little easier gear for climbing.

Having been devoted to full Dura Ace components and drive chains for over 20 years, I've migrated to full Ultegra without any loss of quality or performance. Even with marginal weight gains, the significant cost savings of Ultegra makes it a no-brainer. If I were a paid pro I'd surely go full Dura Ace, but as an avid high mileage endurance road rider footing my own expenses Ultegra has never disappointed.

Great price on a new cassette

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.

These Ultegra cassettes never fail me. I stop noticing them until I use another bike with a lower quality cassette and the shifting isn't quite as crisp.

As always Bike Tires is awesome when it comes to service and swift response.

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.

With removal of 0.85 mm from aluminum carrier it will fit on a 10s freehub. Lathe or Milling machine and expertise required. Try it at your own risk.

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.

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

It is well made and worth the extra money over the 105.

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.

What can you say? Been using Shimano cassettes for years and they are the best! Great price on BTD too.
