HYPERGLIDE+ cassettes offer a revolutionary off-road shifting system with seamless shifting at both extremes of hot range. Now it's time for technology to change road cycling too. Even with maximum effort on a climb or shortly before the finish, you don't have to slow down to change gear. DURA-ACE R9250 drivetrains offer maximum efficiency in every gear thanks to the larger sprockets and are still suitable for existing 11-speed Shimano bodies. In addition, DURA-ACE CS-R9200 cassettes now have 12 gears and weigh less, setting a new benchmark for on-road shifting.

・Faster, seamless shifting under maximum pedal pressure
・Refined 12-step gear combination delivers optimal efficiency and acceleration performance for any situation
・Suitable for the new 12-speed and 11-speed body.
