Overview
Front Derailleur Shimano GRX FD-RX825 Di2 brazed-on 2x12-speed
The Shimano GRX FD-RX825 Di2 is a high-performance electronic front derailleur for gravel and cyclocross bikes, engineered to deliver precise and reliable shifting in the most demanding conditions. As part of the GRX Di2 RX825 series, it combines digital accuracy with gravel-specific geometry.
Di2 electronic shifting ensures fast, quiet and consistent front shifts regardless of load or terrain. The system minimizes the risk of chain drop look and keeps the chain optimally aligned at all times. Firmware updates and system customization are easily managed via the E-TUBE platform.
Supporting front chainrings up to 48T with a 17T total capacity, the FD-RX825 offers a wide and practical gear range for gravel riding. The 47 mm chainline improves tire and frame clearance, enhancing reliability in muddy and dusty environments. A brazed-on mount provides a lightweight and stiff interface with the frame, and the derailleur is compatible with 12-speed HG chains.
