The Shimano GRX RX-820-F 2 x 12-speed front derailleur delivers smooth, reliable shifting for mixed terrain riding.
Its innovative link design and integrated tensioner make adjustment straightforward, while the outward-shifted chainline provides an extra 2.5 mm of tyre clearance—essential for wider tyres and unpredictable surfaces. Built for gravel and adventure cycling where precision and durability matter.
