At Escapa, you’ll find all Shimano electronic drivetrain components.
The Shimano GRX Di2 FD-RX825 2x12-speed front derailleur was developed specifically for Gravel riding and is designed to provide maximum tire clearance. Thanks to the generous chain guide and a 2.5mm offset chainline, it’s now possible to fit extra-wide tires, which are becoming increasingly popular on Gravel bikes.
With a chainring combination optimized for Gravel riding—48/31 or 46/30 in the front—paired with an 11-34 or 11-36 cassette, this drivetrain offers an extremely wide gear range so you can ride at a comfortable cadence whether you’re on flat terrain, trails with ascents and descents, or tackling tough climbs.
The new Di2 wireless platform ensures fast and smooth shifting on the front derailleur.
It also lets you choose between manual shifting and synchronized shifting modes—SEMI-SYNCHRO or FULL-SYNCHRO.
In SEMI-SYNCHRO mode, the rear derailleur automatically adjusts to avoid large jumps in gear ratios so you can maintain your cadence and pace.
In FULL SYNCHRO mode, the rear derailleur and front derailleur work together seamlessly so you’re always in the right gear and don’t have to worry about a thing. Seamless communication with the rear derailleur, combined with programmed chain-guide control, minimizes the risk of the chain skipping.
The fully synchronized and semi-synchronized shifting modes can be selected in the E-TUBE app. Thanks to the digital precision of electronic shifting and the coordinated communication between the front derailleur and rear derailleur, the Shimano GRX Di2 FD-RX825 front derailleur delivers an excellent shifting experience.
