With a +2.5 mm chainline, the GRX front derailleur provides extra tyre and mud clearance, making it ideal for modern gravel bikes running wider rims and higher-volume tyres. The result is smoother, quieter drivetrain performance, even when the terrain gets rough.
Designed for 2x gravel setups, the FD-RX810 offers fast, accurate gear changes and supports a 17T capacity with 46–50T outer chainrings. Its braze-on mount ensures a clean, secure fit, with optional adapters available for non-braze-on frames. Compatible with 11-speed HG chains, it’s the perfect upgrade for riders seeking Shimano’s class-leading shifting performance on gravel, adventure, and all-road bikes.
