Abstract
A sprocket assembly for a bicycle having a large sprocket and a small sprocket. The large sprocket includes chain support projections formed on the side surface opposed to the small sprocket. Each projection includes a contact portion defining a contact surface for contacting, without meshing, a lower end of a chain shifted from the small sprocket to the large sprocket. The chain support means are arranged for causing the contact surface to contact the chain engaging the small sprocket and pick up the chain radially outwardly of the large sprocket during a chain shift from the small sprocket to the large sprocket.
