Front Derailleur

FD-R7150 - Front Derailleur image

The FD-R7150 is Shimano's new 105 12 speed Di2 Front Derailleur, used with the semi-wireless R7150 groupset released in 2022.

It works with the BT-DN300 battery and EW-SD300 Electric Wire.

Since this is essentially the older FD-R8050, it has a top limit bolt. To set up the front derailleur correctly, take a look at my page on setting R7150 105 front derailleur limits.

Wireless, but wired

So the new Di2 components are wireless but still have E-Tube Ports. What gives?

The new Di2 system is only semi-wireless, meaning that the derailleurs are still plugged into the battery. The shifters send their shift commands wirelessly, but Ultegra and Dura-Ace shifters can be wired to the rest of the system to increase battery life.


This 105 Di2 front derailleur is meant to be used with a 12-speed rear derailleur. It is compatible with all 12-speed Di2 road rear derailleurs.
