Abstract: A bicycle sprocket comprises a sprocket body and sprocket teeth. The sprocket teeth include at least one first tooth. The at least one first tooth has a first maximum chain-engaging width, a first tooth center plane, a first projection, and a second projection. The first maximum chain-engaging width is defined in an axial direction parallel to a rotational center axis. The first tooth center plane is defined to bisect the first maximum chain-engaging width in the axial direction. The first projection has a first maximum axial length defined from the first tooth center plane in the axial direction. The second projection has a second maximum axial length defined from the first tooth center plane in the axial direction. The second maximum axial length is different from the first maximum axial length.
