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 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 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).
