Bicycle front derailleur

A bicycle front derailleur for selectively shifting a chain from one sprocket to another of a multiple chainwheel, the front derailleur comprising a parallelorgrammatic pantographic link mechanism which includes:

• a base member fixable to a suitable portion of a bicycle frame;
• an inner link member located laterally closer to a bicycle frame, the inner link member having an upper end pivotally connected to the base member by a first pin for pivotal movement laterally of the bicycle;
• an outer link member located laterally farther from the bicycle frame than the inner link member, the outer link member having an upper end pivotally connected to the base member by a second pin for pivotal movement laterally of the bicycle;
• and
• a movable member pivotally connected to respective lower ends of the inner and outer link members by third and fourth pins, the movable member being provided with a chain guide including an inner guide plate and an outer guide plate, the inner and outer guide plates being opposed to each other with the chain positioned therebetween;
• wherein the link mechanism is biased by a spring so as to return the movable member laterally inward;
• and
• wherein the inner link member is provided with an actuating arm extending laterally outwardly toward the outer link member, the actuating arm being pivotable integrally with the inner link member, the actuating arm having a free end connected to a cable for pulling the actuating arm upward.
