Shimano Tiagra FD-4703 3-/10-speed Front Derailleur

The Tiagra front derailleur FD-4703 by Shimano - for smooth front shifting

The Shimano Tiagra front derailleur FD-4703 can be used for three chainrings, the largest of which may have 50 teeth. In combination with a 10-speed rear derailleur, this results in a smooth and reliable shifting function on a road or city bike. The front derailleur is compatible with modern HG-X Mountain bike chains, which are guided very safely thanks to the fine tuning. The parallelogram is made of light aluminium, the cage plates are made of steel. The FD-4703 is available for clamp and braze-on mounting.
