BICYCLE SPROCKET AND MULTIPLE BICYCLE SPROCKET ASEMBLY

摘要

A bicycle sprocket has a sprocket main body, a plurality of teeth disposed on the sprocket main body, and at least one shifting area. The teeth include at least one first tooth having a first maximum axial width and at least one second tooth having a second maximum axial width. The first maximum axial width is larger than the second maximum axial width. The first tooth is configured to engage with an outer link plate of a chain. The second tooth is configured to engage with an inner link plate of the chain. The at least one shifting area includes an area where a chain engages with one of the teeth during shifting from a small sprocket to the bicycle sprocket and an area where the chain separates from one of the teeth during a shifting action from the bicycle sprocket to the small sprocket.
