Shimano Dura Ace R9200 – The Science of Speed

Speed was the mainspring in the development of this next generation road bike 12 speed groupset. Several years of research produced those innovations that make the Shimano Dura Ace R9200 even faster. Every component has been reviewed, refined and optimized to allow for those decisive seconds of advantage, whether in a breakaway from the peloton or in the final sprint on the Champs-Élysées.

In the Di2 electronic version, the Dura Ace relies on wireless technology where it counts to make shifting even faster and more reliable. Smooth shifting is also the goal of the Hyperglide+ system, already known in the MTB segment, which is designed to bring out the maximum performance and potential of each rider.

Hyperglide+

Conventional Hyperglide technology provides smooth gear changes thanks to small shift ramps that move the chain to the next largest sprocket. The Hyperglide+ takes over this function, but also applies it in the opposite direction to prevent the chain from falling when descending. The result is a smooth, consistent ride in both directions, with no bumps and no loss of cadence.
