  • Shimano Ultegra R8070 Di2 Disc Brake Groupset

    The Shimano Ultegra R8070 Di2 Disc Brake Groupset provides exceptional, market-leading electronic gear shifting thanks to the Di2 system. This system ensures shifting accuracy, which provides crisp and precise shifts with every push of a button. No adjustment is required once setup, instead of mechanical cables you have fully sealed, high-end Di2 electronic wires that relay your gear selection instantly; this truly is the essence of modern, electronic drivetrain efficiency.

    Exceptional Ultegra Hydraulic Disc Brake Performance

    This groupset is also equipped with among the most advanced hydraulic disc brakes in the industry. For many years Shimano has been pushing the development of disc brake technology for mountain bikes, now this exceptional brake feel, modulation and superior braking power is available on road bikes.

    Electronic Synchronised Front and Rear Shifting Reliability

    For the first time in an Ultegra groupset, Shimano’s innovative Synchro Shift is now available as a programmable Di2 option; Synchro Shift creates an intuitive experience with synchronised front and rear shifting, which can be custom programmed. With 'full' and 'semi' Synchro Shift available, this intuitive new mode automatically reacts when you shift from one chainring to another. Remove the guess work as your rear derailleur shifts automatically to minimise the gear step so you can keep riding with a smooth cadence and rhythm.

    Di2 E-Tube Unmatched Shifting Performance

    The Di2 E-Tube system provides unmatched shift performance, reliability and rider customisation. Along with enhanced Di2 functionality, the front and rear Di2 derailleurs are connected via Shimano’s small EW-WU111 wireless unit allowing for an ANT Private connection between the drivetrain and third party devices. These components can be connected to Shimano´s E-Tube software, which supports the programmable aspects of the Di2 electronic gear shifting system. Use the Bluetooth technology for seamless access on smartphones and tablets.
