Brand new Shimano Dura-Ace CS-R9200 11-34T 12-Speed Cassette.

The Shimano Dura Ace CS-R9200 -12 cassette offers smoother, quicker gear changes with Hyperglide Plus technology. You don’t have to lift the pedal to change gears, even on climbs or near the finish line.

In all gears, the DURA-ACE maximizes efficiency thanks to larger gears while maintaining compatibility with existing 11-speed driver bodies. All this with an increase to 12 gears and no weight gain.

Whichever gear you choose, the Dura-Ace drivetrain maximizes efficiency with a larger sprocket while maintaining compatibility with the 11-speed cassette body.
