Shimano Dura-Ace R9270 Di2 Disc 12-Speed Groupset without Bottom Bracket
Shimano's Dura-Ace R9270 Di2 Disc Groupset is the pinnacle of the brand's road technology, engineered for speed, smooth operation and sleek aesthetics. In this latest edition there are a number changes including better ergonomics in the shifters for improved functionality and comfort in all hand positions, increased braking modulation, faster shifting, and, of course, the additional 12th sprocket and the move to a semi-wireless configuration.
Semi-wireless
Shimano Dura-Ace 12-Speed is semi-wireless. This sees both derailleurs connected to a central battery, with the shifters then connecting wirelessly to the system. The rear derailleur houses the brains of the system, and is also where the groupset is charged.
