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

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.

Very quick delivery and a great price. No problems encountered.

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!

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.

100% roadie who isn't afraid of the dirt/water/and other perfect road conditions approves this cassette for all your cycling needs!

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!

Quality cassette at a great price! I'm running a standard crank with the 11-30 cassette and love it! I could do 11-32 so I could spin more but not complaining here!

The new CS-R8000 cassette benefits from trickle-down technology from the DuraAce group as the lowest (largest) five gears are affixed with spiders which makes the spacing between gears more accurate and shifting becomes even smoother than in previous versions of Ultegra cassettes.The only penalty is a slight increase in weight versus the DuraAce version. It is certainly a bargain, especially if it's on sale at BTD.

Kudos to Shimano for creating a very affordable high performing cassette. Shits up and down super smooth. No need for dura ace if you have this (unless youre a weight weenie).

Shimano ultegra is the best without the high price

Simply the best bang for your money. Dura Ace weight savings not worth the price difference.
