ーラ−０A guide mechanism including a first pulley plate, a guide pulley and a tension pulley rotatably supported by the plate via a pulley shaft is movable in the axial direction of a multi-stage sprocket device attached to a rear wheel hub of a bicycle. The chino supported and guided by the guide mechanism is replaced with one sprocket of the multi-stage sprocket device, and the chino is prevented from falling off on the side opposite to the spoke side of the rear wheel in the tension pulley. A bicycle rear derailleur is provided with a second pulley plate that moves toward the spokes of the rear wheel when shifting to a low speed, and the tip position of the second pulley plate moves toward the spoke side of the rear wheel so that the pulley shaft of the tension pulley is aligned with the pulley axis of the tension pulley. A bicycle rear derailleur-0, characterized in that the spokes are deviated forward in the forward movement direction from the forward movement locus of the spokes, and have a bulge portion bulging toward the tension pulley at the tip end thereof.
