Shimano Ultegra Di2 R8150 Groupset 2x12

With the Ultegra Di2 R8150 groupset from Shimano, you’ll reach the pinnacle of road performance and benefit from the technologies of the top-tier Dura-Ace series – but in a more affordable package. The electronic semi-wireless shifting system delivers precise and lightning-fast gear changes, making your ride more efficient. Thanks to the 12-speed cassette, you get a wide range of 11-34 teeth with finely spaced gears. Shimano has eliminated the need for cable routing between the shifters and derailleur – only one wire remains between the battery and the derailleur or front mech, providing a clean look and simple installation. With powerful hydraulic disc brakes, you’ll enjoy maximum control and safety at all times – whether the weather turns or the descents get long. The flat-mount design ensures the brakes integrate seamlessly into the sleek profile of your road bike. Upgrade to the Ultegra R8150 and experience top-tier technology on your favorite loop.
