Shimano Dura Ace CS-R9200 Cassette 12-speed - silver

Dura Ace R9200 - The Science of Speed Speed was the driving force behind the development of this new generation 12-speed road bike groupset. Several years of research produced the innovations that make the Shimano Dura Ace R9200 even faster. Every component has been reworked, refined and optimized to give you the decisive seconds advantage - whether as a breakaway from the peloton or in the final sprint on the Champs-Élysées. In the electronic Di2 version, Dura Ace Wireless technology is used where it counts to make shifting even faster and more reliable. The Hyperglide+ system, already familiar from the MTB segment, is also aimed at smooth shifting and is designed to bring out the maximum performance and full potential of every racer. Hyperglide+ technology has already set standards in the off-road sector, where it has impressed with its smooth shifting in both directions across the entire gear range. With the Shimano Dura Ace CS-R9200 cassette, this concept is now also finding its way onto road bikes to ensure worry-free upshifting and downshifting, whether you're exerting maximum effort on climbs or sprinting to the finish line. While larger teeth ensure maximum efficiency, the switch to 12 gears does not increase the weight. And the 12-speed cassette is even compatible with Shimano's previous 11-speed freehub bodies. This makes the CS-R9200 the cassette of choice for road bikes.
