Bicycle sprocket and bicycle sprocket assembly

A bicycle sprocket comprising:

• a sprocket body including a radially outer periphery provided about a rotational center axis of the bicycle sprocket;
• and
• a plurality of chain-driving teeth provided on the radially outer periphery to engage with a bicycle chain, the plurality of chain-driving teeth comprising:
• a first tooth having a first maximum chain-engaging width defined in an axial direction parallel to the rotational center axis;
• and
• a second tooth having a second maximum chain-engaging width defined in the axial direction, the first maximum chain-engaging width being larger than an inner link space defined between an opposed pair of inner link plates of the bicycle chain and smaller than an outer link space defined between an opposed pair of outer link plates of the bicycle chain, the second maximum chain-engaging width being smaller than the inner link space,
• the first tooth having a first width defined in the axial direction, the first width being defined at a reference position radially outward spaced apart from a center point of a reference line by 1.5 mm, the reference line being 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, and
• the first width being 70% or more of the first maximum chain-engaging width.
