Product Description Shimano 105 Di2 FD-R7150 Front Derailleur - Shifting has never been easier The FD-R7150 Di2 is the first electronic 2x front derailleur released by Shimano for the 105 road bike series. It weighs only about 30 grams more than the comparable Ultegra model. You benefit from ground-breaking innovations such as the Synchro Shift mode, in which the front derailleur automatically selects the appropriate chainring depending on the position of the rear derailleur. This makes the shifting process much easier and you can devote your full attention to the riding experience. Or you can go for Semi-Synchro Shift and still operate the front derailleur, but rely on the automatic adjustment of the rear derailleur. This avoids large gear changes and keeps your rhythm consistent. The FD-R7150 has a total capacity of 16 teeth and is compatible with large chainrings up to a maximum of 52 teeth and a chainline of 44.5 mm. It is designed for braze-on mounting, but with the help of a suitable adapter it can also be installed on the frame using a clamp. You connect it to the battery via a cable, which in turn is also connected to the rear derailleur. The inner parallelogram and the deflectors of the front derailleur are made of steel, the outer parallelogram is made of durable composite material to save weight.

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 Synchronized Shift 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.
