Overview
Front Derailleur Shimano Dura-Ace FD-9150 Di2 brazed-on 2x11-speed
The Shimano Dura-Ace FD-9150 Di2 is a professional-grade electronic front derailleur engineered for uncompromising road racing performance. Part of the Dura-Ace R9150 series, it delivers ultra-fast, smooth and precise shifting even under very high pedaling loads.
Di2 electronic shifting combined with SHIMANO SYNCHRONIZED SHIFT technology (full and semi-synchronized modes) automatically coordinates front and rear derailleurs. Programmed trim settings reduce chain rub and ensure flawless operation across the entire gear range.
The Down Swing design provides stable chain control and rapid response in all conditions. A brazed-on mount ensures a lightweight and stiff interface with the frame. Compatible with 50–55T front chainrings, offering a 16T total capacity, and optimized for a 43.5 mm chainline. Works with HG-EV and HG-X11 11-speed chains and frames featuring a 61–66° chainstay angle.
