Shimano Dura-Ace FD-R9150F Front Derailleur

The front derailleur of the Dura Ace Di2 group is a mechatronic unit that presses the chain precisely and quickly onto the desired chainring. In interaction with the stiff chainrings, with their perfectly coordinated shifting aids, shifting operations are completed in the shortest possible time.
Typical problems with the gears, such as adjusting the derailleur, no longer exist thanks to the electronics! The auto-trim function saves valuable time because the derailleur is readjusted automatically, depending on the gear ratio.
