ABSTRACT:
A front derailleur for a bicycle has a four-point link mechanism, and a control cable is attached by a screw to an end of a connecting arm fixed to one link of the four-point link mechanism. The connecting arm has an auxiliary projection. The control cable applies a torque to the link at a point of contact between the control cable and the auxiliary projection. The screw on the connecting arm is spaced from a chain guide which contacts a chain, to facilitate an operation to attach the control cable to the connecting arm.
