Smooth shifting and riding

Smooth shifting and riding

Seamless replacement for my 49 thousand mile Ultegra 6800. Regularly replace your chain and these babies last almost forever.

Dependable and my fav group set

Shimano. It works.

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.

Biketiresdirect once again filled my needs. Great prices and great products. This cassette is well worth the money and great quality.

We have lots of options on where to get bike products. Ordering from this company is great; their pricing is competitive and fair, they offer great perks, and I have faith that the products are authentic and not knock off's. This cassette works as it should and came quickly. Thank you!

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.

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.

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.

easier to pedal in the big sprocket but goes faster in the little ones

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.

love it... quiet.. use it on sram etap... i think it is better than red cassettes

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.

Used to replace Dura Ace cassette. Its heavier but no drop off in shifting.

I have been riding SRAM for the past 10 Years and I changed to Shimano last year. The shifting is smooth as butter and easy on the hands. So far it has been a good change.

Upgraded from an 12-25 105 cassette to an 11-28 Ultegra cassette (hills) and can actually feel smoother shifting with all of the rest of the components remaining 105.

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.
