A drive arrangement for a bicycle has a multi-sprocket arrangement for a rear wheel hub of the bicycle. The multi-sprocket arrangement comprises a plurality of sprockets with different diameters, wherein the sprockets each have a plurality of teeth which are separated by tooth spaces, and which can be placed in engagement with a drive chain with wide and narrow chain links which follow one another alternatively in succession. On a circumference of at least a starting sprocket of the plurality of sprockets, at least one sequence of teeth is provided at a location where a changeover of the drive chain from the starting sprocket to a selected sprocket occurs. The sequence of teeth comprises a first tooth having a tooth base that is tangent to a root circle of the starting sprocket or lies radially outside of the root circle, and at least one additional tooth which follows the first tooth lies with its tooth base radially within the root circle of the starting sprocket.
