Shimano 105 FD-5703 3-/10-speed Front Derailleur

The 105 front derailleur FD-5703 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.

Technology:

DUAL SIS
After the rear derailleur, the index shift system with its fast, precise and clean gear changes was also transferred to the front derailleur. Index front derailleurs make shifting easier and more comfortable.

Wide Link
The greater distance between the bearing points increases rigidity and stability. Especially with Dura Ace, Ultegra and 105, the inner and right parallelogram bodies have been made wider for greater strength. Twisting is prevented, so that gear changes are more crisp, precise and fluid - even when you get out of the saddle.
