ABSTRACT:
A bicycle sprocket is provided with a metallic sprocket ring part and a non-metallic inner ring part. The metallic sprocket ring part has a crank facing surface, an opposing surface, an inner periphery and an outer periphery with a plurality of sprocket teeth arranged thereon. The sprocket ring part includes at least one connecting portion integrally formed with the sprocket ring part as a one-piece, unitary member. The non-metallic inner ring part at least partially overlaps the inner periphery of the metallic sprocket ring part to at least partially non-movably couple the non-metallic inner ring part to the metallic sprocket ring part with at least one selected portion being absent of the non-metallic inner ring part to allow relative elastic deformation between the metallic sprocket ring part and the non-metallic inner ring in an axial direction.
