The Shimano GRX FD-RX825 12-Speed Di2 Front Derailleur (Braze-On) is a high-precision electronic shifting component engineered for gravel riders who demand crisp, reliable front shifting in all conditions. As part of Shimano’s GRX 12-speed Di2 lineup, this front derailleur delivers fast, accurate gear changes with minimal effort — whether you’re climbing rough gravel, navigating technical terrain, or accelerating out of corners.

Designed specifically for gravel use, the FD-RX825 features a braze-on mount for direct, secure attachment to compatible frames.

Shimano’s advanced Di2 software manages precise front shifts even under load, reducing chain rub and improving drivetrain efficiency. The gravel-specific cage profile and optimized geometry help guide the chain cleanly across chainrings, enhancing reliability in muddy, dusty, or wet conditions. Because it’s electronic, shifting performance remains sharp regardless of grime or cable wear — a significant advantage on long off-road rides.... Read More
