Shimano GRX Di2 FD-RX815 2-/11-speed Front Derailleur

The GRX Di2 FD-RX815 front derailleur by Shimano gives you more tyre clearance
The Shimano GRX Di2 FD-RX815 electronic front derailleur features a chainline that is 3.5 mm further out (compared to a conventional Shimano road front derailleur), making it compatible with wider tyres and rear triangles. With its 17 tooth capacity it fits perfectly to the Shimano FC-RX810-2 crankset. Thanks to this front derailleur nothing stands in the way of your next gravel adventure with a 2x setup.

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 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.
