Shimano Dura Ace CS-R9200 Cassette, 12-speed

Shimano Dura Ace CS-R9200 Cassette, 12-speed

The CS-R9200 is the first cassette from Shimano's top-of-the-range Dura-Ace road series to have 12 sprockets. Since five or six sprockets are made of titanium, depending on the gradation, this saves up to 90 grams in weight compared to the Ultegra model. The cassette features Hyperglide+ technology, which was first tested in the MTB sector and ensures seamless shifting even under heavy load. You can even change gears safely and instantly when pedalling or sprinting. The gradations have been selected to ensure high gear efficiency in all situations as well as optimal acceleration. The enlarged teeth of the pinions also contribute to this. A special plus point is its compatibility: CS-R9200 not only fits on the new 12-speed freehub body, but can also be used with conventional Shimano road freehub bodies.

TECHNOLOGIES

Hyperglide+ is the efficient further development of the Hyperglide system by Shimano. These are shifting aids and specially shaped sprocket teeth that make shifting to larger or smaller sprockets suppler, smoother and quieter. The system of small rivets and ramps machined or pressed into the side of the sprocket ensures that the chain is taken along by the next sprocket before it leaves the previous sprocket. Hyperglide+ is optimised for faster shifting and shifting under load and, in combination with an HG+ chain, has more efficient chain connection, retention force and power transmission. Compared to Hyperglide, the shifting time is reduced by one third and the pedal stroke is noticeably reduced. It enables a completely new chain stability and thus offers a safe riding experience.
