Shimano Dura Ace Di2 2x12-speed FD-R9250-F R9250 9250 Road Front Derailleur. 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. High shifting speed: 45 % faster than FD-R9150. Slimmer, flatter and lighter than predecessor.

Front area reduced by 33 %, thereby less wind resistance. Connected to battery via cable.

Fully- and semi-synchronous shift mode adjustable (via E-Tube or rear derailleur). Firmware updates via E-Tube Project. Inner parallelogram and baffles plated. Di2 systems are the electronic shifting systems from Shimano.

They are based on the SEIS, the Shimano Electronic Intelligent System, which takes over the index shifting function from the mechanical components, only via power cables or radio signals and not via a Bowden cable. Shifting is done by simply pressing a button. This has the advantage that no great effort is required, your concentration on the ride is not disturbed and operation is easy even with cold hands.

In addition, the electronic gear changes are very fast and highly precise. There is also no risk of a defective circuit due to dirty cables or other problems. You can adjust individual settings via the E-Tube Project, such as adjusting the shifting speed, the number of shifting operations per button press or the Synchro or Semi-Synchro shifting function.

Shimano offers an app for this purpose. Gear maintenance and firmware updates are also done via E-Tube, with the bike connected to a PC running the appropriate E-Tube software for more extensive workshop work.

Shimano's synchronised shifting function is a shifting mode that automatically matches the Di2 rear derailleur and Di2 front derailleur. It is activated either via the E-Tube platform or via the rear derailleurs with a function button.

Synchro Shift means that the front derailleur automatically selects a suitable gear depending on the position of the rear derailleur, while Semi-Synchro Shift means that a suitable rear derailleur position is automatically set when you operate the front derailleur. This gives you the advantage that you only have to concentrate on one side of the shifting process and are not thrown off-rhythm by sudden unfavourable changes to the gear ratio. Application: Road, Triathlon & Time Trial. Gearing: 2x (in combination w/ 12-speed). Chainstay Angle: 61 - 66°.
