Meet The New Dura-Ace 9100 Cassette

Upgrade your gearing to the incredible dependability and meticulous engineering of Shimano’s 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 in the pro peloton to immediately detect.

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.

Features:

• Ride with more intuitive gearing on this improved cassette from Shimano
• Precisely machined cogs balance weight and durability
• Carbon and alloy carrier blends low weight and strength
• Titanium (top 5) and nickel-plated steel (smallest 6) construction
• Carbon fiber and alloy carrier
• Available in 11-25t, 11-28t, 11-30t, 12-25t, 12-28t options
• Compatible with Shimano 11-speed hubs
• Weight: 187g (11-28t)
