Shimano Dura-Ace Di2 ST-R9150 11-speed double chainring electronic road bike shifters

Take advantage of this exceptional offer to upgrade your Shimano Dura-Ace 11-speed R9150 groupset!

This pair of shifters incorporates the latest Shimano design technologies. Synchro Shift technology allows the derailleurs to position the chain on the optimal sprocket or chainring when the cyclist initiates a gear change via one of the shifters. This results in more intuitive gear changes, with the benefit of an optimal chainline at all times and no chain crossing. Synchro Shift mode can also be deactivated when you wish to take full control of the derailleurs. Beyond this new adjustment mode, gear changes have become even smoother and more precise, establishing the new Dura-Ace 9150 as the benchmark electronic drivetrain.

They also feature a redesigned shape to offer improved ergonomics, reduced weight and a better grip. Every detail has been carefully considered, and the impeccable finish results in a very understated aesthetic.
