Science of Speed
We take years to give you seconds. The pinnacle of Shimano road technology and innovation, the new 12-speed DURA-ACE R9200 and ULTEGRA R8100 groups are our fastest, most inspired drivetrains ever.
Speed was the driving force behind the new generation of road groups, and every decision our designers made was to make you faster. Shimano engineers worked to refine each component and every function to provide the best on-bike experience, whether you’re sprinting to the finish on the Champs-Élysées or crushing your local climb.
Shimano’s new premium 12-speed Di2 electronic road groups not only feature the proven HYPERGLIDE+ technology that revolutionized mountain bike shifting, but the new, wireless cockpit takes cycling’s fastest electronic shifting system and makes it even faster. A new, proprietary wireless protocol increases shifting speeds without sacrificing even a tiny fraction of Shimano’s hallmark precise and reliable shifting performance. Battery life is also best-in-class, with a centralized battery that delivers approximately 1,000 kilometers of worry-free riding on a single charge.
Completely redesigned hydraulic disc brakes balance speed control and stopping power like never before. DURA-ACE and ULTEGRA brakes feature easier maintenance as well as better modulation and control. Rounding out the new group, Shimano introduces a brand-new lineup of DURA-ACE and ULTEGRA wheels that perfectly blend rigidity, aerodynamics, and weight for every type of rider and every terrain. At the intersection of innovation, reliability, and control, Shimano’s new 12-speed road groups redefine the meaning of speed with precision shifting and premium performance.
