Abstract
A bicycle front derailleur that is movable between shift positions in association with an indexer. The inner mechanical end stop is adjusted at the first indexing position so there is no loosening of the control cable in the last downward gearshifting operation, with the benefit of an immediate and rapid response in the first upward gearshifting operation. The outer end stop is adjusted to interrupt the rotation of the cable-winding bush before it reaches the last indexing position. This pair of mechanical end stops limits the excursion of the derailleur to prevent it being able to shift the chain too much towards the frame or too much away from the frame, which ensures that the chain is not shifted beyond the gears.
