ABSTRACT:
A bicycle derailleur gear change provides improvements to existing systems which utilize a pivoted yoke carrying the pivots of a chain guide roller and a chain tension roller and a displacement device which includes two parts one of which is fixed to the bicycle frame and the other supports the guiding device and moves relative to the first to move the guiding device transverse to the bicycle wheel and across the gear change sprockets. In the present device the guiding device has a guide lug which pivots relative to the yoke in a plane perpendicular to the axis of the sprockets and common with that of the cheek of the yoke. A mechanical linkage is connected to the displacement device and pivots the lug when the guiding device moves transversely so as to bring the free end of the lug adjacent the selected sprocket corresponding to the position of the guiding device.
