Your cart is empty.Shimano's groupsets often often miss call-outs for European elegance or relentless pursuit of weight loss at all cost and innovation for innovation's sake, instead earning their loyal following through the incredible dependability and meticulous engineering of the Dura-Ace CS-R9100 11-Speed Cassette. 9100 isn't a typo there, it is, in fact, a newly reworked version of Dura-Ace. When the brand introduces a new groupset, you can be sure it's actually boasting improvements you don't have to be Porte or Stannard to detect on a routine Sunday in the saddle. Since Dura-Ace is the top-tier drivetrain in the Shimano road lineup, you might be surprised that only the largest five cogs are titanium. That's because—though it's lighter—titanium is generally more prone to wear than nickel-plated steel, and the smaller cogs are more prone to wear than the larger. Because of these material properties, Shimano only uses titanium where the softer metal doesn't create a significant negative impact.

Gave me a touch better climbing gear without affecting the speed gears.

Tuve una lesión en isquiotibiales y me impedía rodar de subida, con esto el dolor desaparece y ya recuperado mantendré la cadencia en subidas pronunciadas

I replaced the Shimano Dura-Ace 11-28 cassette on my S-Works Roubaix with an 11-30 cassette to assist with climbing mountain roads. The extra gear certainly helps on long climbs.

Wow. What a difference 30 teeth makes. I live in Southern California, and its super hilly around here. I am terrible at hills, and need all the help I can get.....this cassette does the trick. Plus it's a seriously cool - titanium and carbon and all that. Much cheaper than I expected it to be with all its bling factor.

I needed a 30T so I could get my bike and butt up and over the Continental divide near Leadville, Colorado. It did the trick and works as expected with my old Dura Ace triple components.
