  • The FD-R9250 Dura-Ace Di2 Front Derailleur by Shimano - Slimmer, flatter, lighter.

    The FD-R9250 electronic front derailleur for the Dura-Ace Di2 2x12-speed road bike groupset from Shimano has a more compact design than its predecessor, and is therefore even more aerodynamic. Thanks to baffles made of lightweight aluminium, there is a weight advantage of approx. 15 grams compared to the Ultegra model. With a total capacity of 16 teeth, this allows large chainrings with a maximum of 50 to 54 teeth to be shifted, whereby the shifting speed has been increased enormously compared to the past. The front derailleur is compatible with a chainline of 44.5 mm and is designed for braze-on mounting. With the help of a suitable adapter, however, it is also possible to mount a clamp on the frame. It is connected to the battery via a cable, which in turn is also connected to the rear derailleur and, if applicable, the STIs. Of course, FD-R9250 has the proven Synchro and Semi-Synchro Shift function, which enables an automated interaction with the rear derailleur and thus makes shifting easier.
