Shimano GRX Di2 FD-RX815 Front Derailleur Info

The Shimano GRX Di2 FD-RX815 Front Derailleur brings electronic precision to a 2x gravel drivetrain — delivering the kind of clean, reliable front shifts that matter most when the road turns rough. Built from aluminum with a braze-on mount, it integrates directly with the GRX Di2 system to keep your shifting consistent across varied terrain without any manual trim adjustments.

The derailleur is designed to accommodate chainrings from 46 to 50 teeth with a 17-tooth capacity, and the cage geometry provides extra clearance for the wider tires common in gravel setups. Paired with 11-speed Shimano-compatible cranksets and chains, it handles the demands of off-road riding while maintaining the quiet, stable operation the GRX lineup is built around.
