Front Derailleur

FD-R9250-F - Front Derailleur image

The FD-R9250 is Shimano's new 12 speed Di2 Front Derailleur, to be used with the semi-wireless R9250 groupset to be 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, so what is a wire doing here? The new Di2 system is only semi-wireless, meaning that the derailleurs are still plugged into the battery, but the shifters send their shift comments wirelessly.

Backward compatibility

This front derailleur is meant to be used with a 12-speed rear derailleur. Just like when Di2 made the jump from 10 speed to 11 speed, this new front derailleur won't work with older 11-speed derailleurs.

BikeRadar published a page on prototypes of these derailleurs being used in races, with photos shot by Cor Vos.
