Abstract
A bicycle multiple sprocket assembly comprises at least two adjacent sprockets which include a larger sprocket and a smaller sprocket. A chain takes a shifting path extending from a selected furrow of the smaller sprocket toward a selected furrow of the larger sprocket at the time of shifting from the smaller sprocket to the larger sprocket. At least two teeth of the larger sprocket immediately following the selected furrow of the larger sprocket with respect to the forward rotational direction of the sprocket assembly are rendered circumferentially asymmetric. The leading edge of each asymmetric tooth is provided with a support face which is offset rearwardly for supporting the shifting chain adjacent a chain link connection.
