Shimano Dura-Ace Di2 FD-R9150 electric front derailleur, compatible with Ultegra

The new Dura-Ace Di2 FD-R9150 front derailleur now features Synchro Shift technology, enabling it to automatically select the optimal chainring based on the cassette sprocket engaged. Synchro Shift therefore enables faster and more intuitive gear changes whilst ensuring a chainline without crossing across the entire gear range. Synchro Shift mode can also be deactivated to allow for manual control.

The new Dura-Ace Di2 features a compact and very understated design. It also offers excellent impact resistance in the event of a fall. Its mechanism ensures exceptional smoothness when changing chainrings, even in the most critical situations.
