The Shimano GRX Di2 FD-RX825 2x12-speed front derailleur was designed and developed specifically for the use of wide tires. The chain line offset by 2.5mm and the generous chain guide make it possible to use particularly wide tires, which are becoming increasingly popular on gravel bikes.
The electronic front derailleur shifts with the utmost precision, as is typical for Shimano.
