The Shimano Dura Ace Di2 FD-9150 Front Derailleur retains all the crisp, speedy, on-demand front shifting from previous models, but it has an increased inboard limit to work with the new position of the inner chainring on 9100 series cranksets. Its electric operation means quick, smooth gear changes even under load, and compatibility with Shimano Synchro Shift allows both front and rear derailleurs to be controlled with a single shifter.
Compatible with Shimano Di2 electronic groupsets only. Braze-on mount. Clamp adapter available separately.
