Shimano Dura-Ace FD-9250 Di2 12-Speed Front Derailleur

The Shimano Dura-Ace FD-9250 Di2 12-Speed Front Derailleur promotes an incredibly minimal silhouette and low weight, but its advanced design contributes tosmoother shifting that is 45% quicker than provided by its predecessor. It’s operated by the gear levers wirelessly via hard wiring to the rear derailleur and internal battery, with this configuration guaranteeing reliability and extended use between battery charges.

The integrated auto-trim feature automatically adjusts its position, depending on which sprocket the rear derailleur is operating, eliminating the chances of annoying chain rub. In addition, an optional Synchronised Shift mode can be selected that will intuitively change the front derailleur between the outer and inner chainrings, depending on the rear derailleur’s position, helping to keep chain lines as efficient as possible. This mode can be selected either via the Di2 app or via the Di2 button on the rear derailleur.
