Description Now with plenty of gearing options, the new Dura Ace cassette is perfect for a variety of riders and applications. And, it's new alloy carrier saves weight and increases stiffness over previous models.
Works best when used with the 7900 series chain but it also compatible with older Shimano 10 speed chains. All sizes are back compatible and work with the RD-7800 or RD-7900 rear derailleur except for the 11/28 model which requires greater chainwrap capacity and the use of the RD-7900.

Top ace
Durango ace set it all. Finest in Japanese craft and precision.

No brainer
You can't beat the quality of Dura-ace. A 11-28 is a cheaper alternative to compact cranks for 55 yr old knees. Shifts just fine

Worth it

Smoother and sure-er shifting than James Bond working a stick in an Astin Martin. Plus it's light, and has the ultra sexy titanium gears.

I use this cassette on my Cervlo R3 and it it procures very precise and smooth shifting. And the price is far more better than in a bike shop here in Qubec.

Nothing shifts as good as the Dura Ace cassette. I installed this on my good wheelset and anxiously await Spring for me to get the good bike back out. Till then it's my clunker bike with the Ultegra groupo that shifts nice but definitely not as good and responsive as Dura Ace!

I use this with a 7900 chain with Ultegra 6703 on the front. I think this works better than Shimano's recommended 6600 chain with the 6703 up front and ultegra cassette in the rear. I love the 11-28 option, as I do a lot of steep climbing. Nothing bad to say except - wow - pretty expensive.
