Shimano GRX FD-RX400 2x10-speed front derailleur
Matched to Shimano GRX chainsets, the GRX FD-RX400 2x10-speed front derailleur is also adapted to a 2.5 mm wider chainline, allowing tyres up to 42 mm wide to be fitted for riding on rough terrain (without original packaging).
For gravel, road and cyclocross bikes: Shimano GRX 2x10-speed front derailleur FD-RX400 with braze-on mount
The RX800 front derailleurs are designed to handle the 17-tooth difference between the sprockets of the RX800 48/31T chainset, while the FD-RX400 front derailleur is perfectly matched to the 16-tooth difference between the sprockets of the RX600 10-speed chainset (46/30 teeth). All front derailleurs deliver the characteristic SHIMANO shifting performance and precision. The Di2 front derailleur can be adjusted easily and intuitively using integrated control functions, while the mechanical front derailleurs impress with smooth operation, a highly ergonomic force curve and an integrated cable fixing and adjustment function.
