Abstract
A bicycle sprocket comprises a sprocket body and a plurality of chain-driving teeth. The plurality of chain-driving teeth comprises a first tooth and a second tooth. The first tooth has a first maximum chain-engaging width defined in an axial direction parallel to the rotational center axis. The second tooth has a second maximum chain-engaging width defined in the axial direction. The first tooth has a first width defined in the axial direction. The first width is defined at a reference position radially outward spaced apart from a center point of a reference line by 1.5 mm. The reference line is defined to connect centers of neighboring pins of the bicycle chain engaged with the plurality of chain-driving teeth when viewed from the axial direction. The first width is 70% or more of the first maximum chain-engaging width.
