The 105 FD-5703 Front Derailleur by Shimano - Precise and clean gear changes

The Shimano 105 front derailleur FD-5703 shifts three chainrings (in combination with 10-speed Road rear derailleurs) smoothly and precisely even under load. This is ensured by the reliable DUAL SIS index shifting function. In addition, the FD-5703's Wide Link design has increased stability and reduced susceptibility to twisting. The front derailleur is available in black and silver.
