摘要： A shift assist projection is provided on a large bicycle sprocket to assist in shifting a chain to the sprocket from an adjacent smaller sprocket. The shift assist projection extends axially from one side of the sprocket. The shift assist projection has an axially facing chain catching surface that faces the center plane and the teeth of the large sprocket to engage an outer link plate of the chain. The chain catching surface is preferably angled a varying amount relative to the center plane of the large sprocket. The chain catching surface preferably has a rearward most rotational edge that is located closer to the center plane than a forward most rotational edge as viewed substantially along a moving direction of the chain when the chain is being shifted from the smaller sprocket to the large sprocket.

摘要： A bicycle sprocket is provided that has a sprocket ring part, a synthetic resin fastening part and at least one attachment part. The synthetic resin 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 least one attachment part is at least partially embedded within the synthetic resin fastening part. The attachment part includes a connecting portion and a radial projecting portion extending outwardly from the connecting portion to space the connecting portion radially inward of the sprocket ring part. The attachment part is formed as a separate member from the sprocket ring part and the synthetic resin fastening part. The synthetic resin fastening part facilitates weight saving, while the attachment part prevents the reduction of fastening power (strength) due to deterioration or deformation of the synthetic resin.
