Shimano ’s Ultegra Di2 R8050 electric front derailleur (to be soldered on)

R8050: smoothness and precision

Shimano ’s Di2 electronic front derailleur features Synchro Shift technology, which automatically selects the optimal chainring based on the cassette sprocket engaged. This intuitive mode ensures a chainline without crossings and can be deactivated to allow for manual control.

The new Ultegra Di2 R8050 features an even more compact and understated design. It also offers excellent impact resistance in the event of a fall, and its mechanism ensures smooth and rapid chainring changes even under stress.
