A bicycle front derailleur includes a base member for attachment to a bicycle frame, a chain guide for guiding a chain laterally inwardly and outwardly of the bicycle frame, an inner link member having a first end pivotably coupled to the base member and a second end coupled to the chain guide, an outer link member having a first end pivotably coupled to the base member and a second end coupled to the chain guide, biasing means for biasing the chain guide laterally inwardly, and an actuating arm fixed to the outer link member for integral movement therewith. The actuating arm extends laterally outwardly from the outer link member so that pulling the actuating arm upwardly causes the chain guide to move laterally outwardly.
