A sprocket assembly for bicycles includes at least two sprockets with different diameters arranged side by side, the larger diameter sprocket having a tooth for supporting the chain during the displacement of the latter from the smaller diameter sprocket to the larger diameter sprocket. This tooth has, to this end, a stepped support surface arranged on the side opposite to that facing the smaller diameter sprocket.
