Front Derailleur

Front Derailleur

Ultegra FD-R8150-F

The FD-R8150 is Shimano's new 12 speed Di2 Front Derailleur, to be used with the semi-wireless R8150 groupset released in 2021.

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

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, but the shifters send their shift commands wirelessly.
