Shimano Ultegra R8070 Di 2disc groupset

Upgrade your bike with the Shimano ultegra R8070 Group; An electronic group with hydraulic disc brake.

Includes Cranks, cassette and chain.

it has the latest Dura-Ace technologies, such as the Synchro Shift and Semi Synchro Shift, thanks to which you can configure to your liking the relationship between the pinions and the chainrings every time you change gear (customizable through the E-Tube application on the computer, tablet or smartphone).

It presents a much more dynamic and elegant aesthetic line, as well as robust. This feature is especially appreciated in the Hollowtech II bottom bracket with 4 arms and oversized cranks but with a strong aero character, which improve rigidity without increasing weight.

The Ultegra Di2 rear derailleur adopts the Shadow design of high-end models to go under the cassette, well protected from possible shocks.

For its part, the front derailleur has a more compact structure and guarantees very quick chainrings.

The aesthetic and ergonomic lines of the Dual Control shifters are inspired by the Dura-Ace R9100, while the interior technology has been revised to improve the quality of the gear changes. A clearer separation between the change buttons improves the operation and makes it more intuitive. Each change has the multi-change option enabled or disabled. They include upper remote change buttons, useful for controlling electronic devices such as GPS (Garmin). Customize each remote by activating or deactivating the multi-change using the E-Tube app
