Abstract
The present invention discloses a front derailleur for a bicycle to shift a chain via a chain guide between at least two sprockets which are attached on a frame of the bicycle. The front derailleur includes a wire extending through a stopper which is attached on the frame of the bicycle for transmitting a tension. An actuating link is connected to the wire in response to the tension for driving the chain guide to shift the chain between the sprockets. A wire guide is mounted on a seat tube of the frame and connected with the wire between the stopper and the actuating link for straightening the wire substantially parallel to the seat tube, thereby reducing a friction between the wire and the stopper.
