THE SCIENCE OF SPEED: Shimano Dura Ace Di2 R9270 12-speed groupset

Shimano has been working for years to give you a head start of seconds. The new 12-speed DURA-ACE R9200 is the fastest groupset ever and the pinnacle of SHIMANO technology and innovation. Speed was the driving force behind the development of this new generation road bike groupset. That's why every component has been revised, refined and optimised to make you even faster - whether as a breakaway from the peloton or in the final sprint on the Champs-Élysées.
