Abstract
A bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, an axially outward protuberance, and an axially inward protuberance. The axially outward protuberance is disposed on an outward facing side of the sprocket body to overlap at least partly with a bicycle chain engaging with a neighboring bicycle sprocket when viewed along a rotational center axis. The axially inward protuberance is disposed on an inward facing side of the sprocket body to overlap at least partly with the axially outward protuberance when viewed along the rotational center axis.
