Abstract: A bicycle chain comprises a first inner link plate. The first inner link plate comprises a first end portion, a second end portion, and a first intermediate portion. The first end portion includes a first opening, a first chamfered section, and a first chamfer-free section. The first chamfer-free section is provided in at least a first chamfer-free angular range when viewed from an axial direction parallel to a first center axis. The first chamfer-free angular range is defined from a first circumferential end of the first chamfered section to a first inner-link longitudinal centerline of the first inner link plate. The first chamfer-free angular range is equal to or greater than 30 degrees with respect to the first center axis.
