Claim 9:
10. A drive arrangement for a bicycle, comprising:
a larger sprocket;
a smaller sprocket adjacent and on an outboard side of the larger sprocket; and
a bicycle chain including:
alternatingly arranged inner link plate chain links and outer link plate chain links, which chain links are connected pivotably to one another by means of chain pins, and
a chain roller provided at each chain pin, wherein the inner link plate chain links have inboard-side inner link plates, each of which include a protrusion in relation to a respectively assigned chain roller in a front lower longitudinal end region of an inner link plate outer periphery is reduced, and is negative at least in regions, in comparison to a protrusion in a front upper longitudinal end region or in a rear lower longitudinal end region of the inner link plate outer periphery, and

wherein, because of the regionally reduced longitudinal protrusion of the inboard-side inner link plates, during the outboard shifting between the two sprockets, a load flank of a last sprocket tooth of the larger sprocket to emerge from an outgoing chain portion does not come into contact with inner link plate outer periphery of the inboard-side inner link plate of a first bending inner link plate chain link.
