The Shimano CS-R9200 is the suitable cassette for DURA-ACE R9200 12-speed group. The most advanced drivetrain is 100 % performance focused and truly revolutionary thanks to the HYPERGLIDE+ technology. THE SCIENCE OF SPEED: Shimano DURA-ACE 12-speed Cassette CS-R9200. Shimano has been working for years to provide you with an advantage of seconds. 12-speed DURA-ACE R9200 is the fastest groupset ever and the pinnacle of SHIMANO technology and innovation. Speed was the key driver for the development of this generation road groupset. That's why every component has been revised, refined and optimised to make you even faster - whether to leave the peloton behind you or to win the final sprint on the Champs-Élysées.

SHIMANO HYPERGLIDE+ cassettes have set high standards in off-road use with their smooth upshifting and downshifting across the entire gear range. Now it's time to use this technology on road bikes as well. Even when riding at maximum power on climbs or while racing to the finish line, you can now shift without having to worry. At all speed levels, the DURA-ACE R9250 components ensure maximum efficiency thanks to larger teeth and are at the same time compatible with existing 11-speed freewheels. The fact that you can switch to 12 gears without increasing the weight makes the DURA-ACE CS-R9200 cassettes shifting benchmark for road bikes.
