Electronic 2x11-speed road bike front derailleur with precise Di2 shifting performance, Auto-Trim and Shimano Synchro-Shift compatibility.

The Shimano Ultegra Di2 FD-R8050 front derailleur was developed for fast, precise and particularly smooth shifting on electronic 2x11-speed road bike drivetrains. Even under high loads, for example when shifting onto the large chainring while riding out of the saddle, the front derailleur operates reliably and in a controlled manner.

Thanks to electronic Di2 control, gear changes are fast and consistently precise. The integrated Auto-Trim function automatically adjusts the position of the front derailleur cage to the respective chain position on the cassette. This largely prevents chain rub and annoying noise.

In combination with compatible Shimano Di2 components, the FD-R8050 also supports Synchro-Shift and Semi-Synchro-Shift. The front derailleur and Rear Derailleurs are electronically coordinated to enable the smoothest possible gear progression and efficient shifting.

Highlights:

• Electronic Di2 shifting: fast, precise and smooth gear changes.
• Auto-Trim function: automatic alignment of the front derailleur to prevent chain rub.
• Synchro-Shift compatible: coordinated interaction between the front derailleur and Rear Derailleurs.
• High shifting performance: reliable upshifting even under load and while riding out of the saddle.
• Ultegra construction: low weight and high-quality aluminum construction.
