Featuring the same cogs-on-carrier design for the largest 5 cogs, this saves weight and increases strength.

Designed to provide superior rider choice, there's a R8000 cassette to suit nearly every riding style and terrain type.

Mew Cassette

I bought 2 cassettes 11-25 & 11-32 to mix and match a customized gearset that Shimano doesn't offet for the 11 speed. Now I have the gearimg for both downhill as well as going up. Make it close to mt Campy 12 speed setup.

Hard to go wrong

With the miles I put in each year, replacing my cassette is a yearly event. It's hard to go wrong with Shimano Ultegra, plenty of gearing options available and will last the entire year without issue and then still be good enough to put on a beater bike.

Can't go wrong with Shimano cassettes

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

Almost seamless

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.

Value, reliability, precision. Pick 3.

If you run 11-speed road components and you have to pay for them, this cassette is superb and there is no reason to go lower or higher in the Shimano range.

Great casette

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.

Quality Shimano Product

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.

Practical for every day use.

Ultegra cassette is a go-to gear for every day use/training. Not too expensive as Dura-ace and not too heavy as 105, just the sweet spot for a competitive racer or practical recreational rider.

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

Ultegra 11-30 cassette

Hard to find.. waited for months for Shimano to get back to work.. BTD kept me updated on revised shipping dates.. finally received! Great fair price. Consider the 30 if your climbs exceed 8~9% on a regular basis.

Solid performer

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.

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.

Smooth, quiet, efficient shifting

There's not much to say about this product other than that it is typical Shimano quality. It's smooth, quiet, and shifts efficiently without hesitation. The narrow gear range of this particular cassette was what I wanted for gravel racing.
