Shimano Dura-Ace CS-R9100 11-Speed Cassette

Why We Like The Shimano Dura-Ace CS-R9100 11-Speed Cassette

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.
