The ultimate road componentry from Shimano is loaded with technology and innovation, to create their fastest, most inspired drivetrains ever. Speed was the driving force behind the new generation of road groups, and every decision Shimano designers made was to make you faster. This new 12 speed groupset redefines the meaning of speed with precision shifting and premium performance.
Shimano Dura Ace DI2 R9270 Disc 12 Speed Groupset 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 kilometres of worry-free riding on a single charge.
Shimano Dura Ace DI2 R9270 Disc 12 Speed Groupset redesigned hydraulic disc brakes balance speed control and stopping power like never before. DURA-ACE brakes feature easier maintenance as well as better modulation and control. The new brake calipers offer increased pad-to-rotor clearance when the brake is disengaged, lessening the likelihood of rotor rub even if a rotor is slightly out of true.
