The Shimano GRX FD-RX825 Di2 Front Derailleur is built for smooth, reliable front shifting on gravel bikes running 2×12-speed drivetrains. Even under heavy pedaling, it delivers fast and precise gear changes, helping you stay in control on varied terrain. A +2.5 mm chainline increases tire clearance compared to standard road derailleurs, making it easier to run larger gravel tires without interference.

Designed around a wider 17-tooth front gear range, this derailleur gives you more flexibility for steep climbs and fast descents. Its also Di2-compatible, meaning you can fine-tune your ride with Full and Semi-Synchronized shift modes, or customize shifting behavior with the new FRONT SHIFT NEXT function. Whether youre racing, exploring, or bikepacking, the RX825 makes shifting smoother, faster, and smarter.

Key Features:

• Wide Tire Clearance – +2.5 mm chainline allows more room for larger gravel tires.

• Expanded Gear Range – Supports a 17-tooth front difference for more gearing options.

• Di2 Customization – Works with Full/Semi-Synchronized shift modes and FRONT SHIFT NEXT.
