Speed was the driving force behind the development of this 12-speed racing bike series. Several years of research led to innovations that make the Shimano Dura Ace R9200 even faster. Every component has been revised, refined, and optimized to allow for crucial seconds of advantage—whether as a breakaway from the peloton or in the final sprint on the Champs-Élysées. In the electronic Di2 version, Dura Ace relies on wireless technology where it matters most, making gear shifts even faster and more reliable. Smooth shifting is also the goal of the Hyperglide+ system, which is already known from the MTB segment and is designed to extract the maximum performance and full potential from every racer.
