A cage is movably mounted to the mounting bracket so that the cage is positioned adjacent to the front sprocket. The cage has a chain-receiving slot, through which a bicycle chain passes. The cage is configured to move in accordance with a shifting operation of a bicycle rear derailleur to maintain alignment with a chain to prevent the chain from falling off the sprocket.
