Dura-Ace CS-R9100 Cassette delivers pro-level precision with optimal weight and durability

What Our Gearhead® Experts Are Saying:


“This cassette has that perfect Shimano feel—crisp, quiet shifts every time. I love how it balances lightweight titanium cogs with steel where it matters most, giving me both performance and longevity without compromise.”


When we’re chasing smooth, flawless shifts and a drivetrain that feels tuned to perfection, the Shimano Dura-Ace CS-R9100 Cassette is the standard we trust. As Shimano’s top-tier 11-speed road cassette, it combines precision engineering, lightweight construction, and legendary reliability for the kind of performance that stands out on every climb, sprint, and descent.


Its carbon and alloy carrier minimizes flex under power, while titanium and nickel-plated steel cogs deliver the ideal mix of low weight and long-term durability. Every shift clicks into place with that unmistakable Shimano consistency—refined, responsive, and whisper-smooth. Whether we’re racing, training, or just pushing for another personal best, the CS-R9100 brings elite-level performance to every ride.
