Shimano CS-R9200 Dura-Ace 12-Speed Cassette

The uninterrupted shifting experience of the Shimano Dura-Ace R9200 12-speed cassette range lets you climb, sprint and push your limits without stopping to think about your next gear change. Larger driving cogs maximize drivetrain efficiency and create compatibility with both Shimano 11 and 12-speed freehub bodies.

• Super lightweight 12speed HG+ cassette with a rigid carbon and alloy carrier for excellent shifting even under the most demanding gear changes
• Hyperglide+ sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load
• Close ratio gearing allows a more efficient use of energy through finer cadence control
• Largest sprockets are mounted on lightweight alloy and carbon carriers to reduce weight and increase rigidity
• 5 largest sprockets are made from titanium to reduce weight without sacrificing strength
• Sprockets are extensively cut away and drilled to further reduce weight without reducing rigidity
• Nickel-plated finish offers hard wearing resistance to corrosion
• Alloy cassette lock ring
• For Super Narrow 12-speed chains

Hyperglide+ cassettes have revolutionized off-road shifting with their seamless shifts both up and down the gear range. Now it's time for the technology to change road cycling. Even during maximal efforts up a climb or nearing the finish line, riders no longer need to back off to perform a shift. In any gear, Dura-Ace R9250 drivetrains maximize efficiency thanks to larger cogs and retain compatibility with existing 11-speed freehub bodies. All this while increasing to 12-gears and without increasing weight, Dura-Ace CS-R9200 cassettes are the new paradigm in road shifting.
