Abstract
The derailleur comprises, between the conventional articulation mechanism which allows the lateral displacement of the chain guide device (12), an additional articulation mechanism (10, 11) whereby the chain guide device (12) can effect a displacement which is substantially free and of large extent in a plane perpendicular to the axis (X--X) of the crank-gear. This very substantially improves the conditions under which the chain is shifted from one chain wheel to another.
