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

Work perfect with my groupset !

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.

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

Nice to have an extra at a good price. Wear item you will have to replace, or an extra with different gearing for climbing.

I wanted the wide gear range available in this cassette and also was glad I could get it at a decent price. I have one of these on another bike and it has lasted a very long time. This one should also last a long time. This is a very good cassette that I'll buy again if the need arises.

started to have poor shifting while on the trainer and realized lubrication was not the issue. Worn cassette and idler wheels were actually the culprits. Installed new cassette and idlers-voila! problems solved

Fitted on my trainer seamlessly. Duplicates my road bike.

The cassette is lighter than the 105 version and feels like it delivers smoother shifting. Not as light as Dura Ace but more durable and more value for the money spent.

Have these on two road bikes. Cannondale Evo Hi Mods- one with DI2 and the other with Dura Ace year. Pretty simple works well all the time with both set ups. Minor weight penalty vs DA cassette but not noticeable. Have one less adult beverage and you made up the weight difference.

I had a 11x28. I talked to my coach about the climbs we were planning to do. I switched to this and was happy I did!

Fair price on genuine parts that are in stock and shipped quick. Thanks BTD!

Sure, DA is a little lighter, but Ultegra is a far better value.

Good quality cassette - easy installation and works well with DI2 - as advertised, and as always, with BTD, ordering was worry-free, processed quickly and acquired at a great price.

This thang just plain works. Aint much money. Works real good. Still going strong like my John Deere. Buy it if you need it.

Great cassette. Great for the ranges I bike in.

I bought this cassette for my new wheelset. BikeTiresDirect has price match and allows you to use points earned from your prior purchases. Super fast delivery in 2 days!!

Highly recommend to anyone who is shopping bike stuffs!

The item ordered was delivered fast and as ordered. I always get great service from Bike Tires Direct.

I've been using Ultegra cassettes for years. Light, strong, durable and silent.

This cassette works real well when climbing.

Wanted a bit bigger gearing which I got at a fantastic price!

Upgraded from Ultegra 6800 cassette and rear derailleur and I'm not dissappointed!
