Shimano 105 R7170 DI2 Disc 12 Speed Groupset

New Shimano 105 goes electronic for the first time, borrowing from top-tier DURA-ACE and ULTEGRA technology and functionality – wrapped up in sophisticated ergonomics. Fewer cables. No clutter. And lightning-fast precision shifts at the touch of a button. Shift under load. Customise your shifts. Go 12-speed

Shimano 105 R7170 DI2 Disc 12 Speed Groupset is beautifully integrated into the design of the bike with no stretched or frayed cables in sight – or to replace. Wireless shifting brings a clean cockpit free of shift wires and ports. While the internal Di2 battery is concealed in the seat post or frameset
