ABSTRACT:
A bicycle sprocket is provided that has a synthetic resin fastening part, to facilitate weight saving and prevent the reduction of fastening power (strength) due to deterioration or deformation of the synthetic resin. The sprocket includes a sprocket ring part and a synthetic resin fastening part. The sprocket ring part includes an inner periphery and an outer periphery with a plurality of sprocket teeth arranged on the outer periphery. The sprocket ring part extends around a central rotation axis. The fastening part is non-movably coupled to the sprocket ring part at a location radially inwardly of the sprocket teeth relative to the rotation axis. The fastening part includes at least one through hole with a metallic tubular member mounted therein and configured to be fixedly coupled to a rotational drive unit of a bicycle. The tubular member has a first fastener contact surface configured to receive a fastening force.
