Elevate your gravel and adventure riding experience with the SHIMANO GRX RX400 front derailleur, a masterpiece of engineering designed specifically for the demands of mixed-terrain cycling. When your ride takes you from smooth tarmac to unpredictable gravel tracks and dirt paths, you need a drivetrain component that delivers flawless, reliable performance.

Engineered for the unique challenges of gravel, this derailleur ensures that your front shifts are smooth, immediate, and require minimal effort, allowing you to maintain your rhythm and power through changing gradients and surfaces. The Shimano GRX RX400 front derailleur offers lighter front shifting operation and easier setup thanks to the new link construction and integrated cable tensioner.

The GRX RX400 isn´t just about clearance; it´s about a refined rider experience. The ergonomic power curve and natural stroke feeling at the lever mean less fatigue on your hands during long-distance adventures. Every shift is intuitive and responsive.
