Dura-Ace Di2 front mech
Shimano Dura-Ace FD-R9250 Di2 Front Derailleur
A sub-100g Di2 front mech for 2x12 Dura-Ace that shifts between rings markedly faster than its predecessor and trims itself automatically. The slimmer body also presents less frontal area to the wind.
Highlights
Why we rate it
Rapid ring changes
A more powerful motor moves the chain between rings quickly and cleanly, even when you are putting the power down.
Automatic trim
The cage repositions itself as you move across the cassette, so there is no chain rub and nothing to think about.
Synchro Shift ready
Pair it with the rear mech to run full or semi-synchronised shifting through the E-Tube app.
Slimmer profile
A more compact body trims frontal area and weight compared with the 11-speed version.
