Matching the Shimano GRX cranksets, the GRX FD-RX400 2x10-speed front derailleur is also designed for a 2.5 mm wider chain line and thus allow tyre widths of up to 42 mm for rough terrain.

The RX800 front derailleurs are designed to handle the 17-tooth chainring difference of the RX800 48/31T crank, while the FD-RX400 front derailleur harmonizes perfectly with the 16-tooth difference of the RX600 crank for 10-speed with 46/30 teeth. All front derailleurs naturally offer the typical SHIMANO shifting performance and precision. The Di2 front derailleur can be easily and intuitively adjusted using the integrated control functions. The mechanical front derailleurs impress with their smooth-running function with a very ergonomic power curve and the integration of tension clamp and adjustment function.

SHIMANO's GRX, the first Gravel-specific component family designed for both fast progress and safe bike handling on loose surfaces, is the result of an intensive and extensive research, testing and development process that incorporates information and feedback from countless riders on trails, forest tracks, gravel tracks and asphalt all over the world.
