Shimano Ultegra R8050 Di2 Groupset

The Shimano Ultegra R8050 Di2 Groupset provides market-leading electronic gear shifting thanks to the Di2 system and trickle-down technology from professional-level Dura-Ace groupsets. 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.

Power and Precision

The power and precision of Di2 is unmatched. It enables beautifully smooth shifting both front and rear. The lack of maintenance and adjustment is impressive: once you’ve customised your Di2 to shift to your preferences, it will continue to do so endlessly.

Synchro Shift

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

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 groupset 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.
