Feel the unrivaled difference of digital shifting with Shimano's state-of-the-art Dura-Ace Di2 Dual Control shift levers for your road bike! Electronic touch pads make shifting faster than ever and the unidirectional carbon brake levers lighten the load by 155g over the Dura-Ace 7900 mechanical version. Shifting has never been so good! Just a simple press of a button transmits shift impulses in fractions of a second - that's 30% faster than the mechanical Shimano Dura-Ace ST-7900 Dual Control Levers. Slim, unidirectional carbon brake levers with a revised pivot location provide better braking modulation, reduce weight and are functionally refined for a more comfortable grip. Reach adjust mechanism accommodates smaller hands and a wide assortment of bar ends. Smooth bracket design is ergonomically shaped for comfort - perfect for long distance riding. Titanium fixing hand and bolt offer further weight savings.
