摘要:
A bicycle chain comprises a first inner link plate and a second inner link plate. The first inner link plate comprises a first inner-link end portion, a second inner-link end portion, and a first inner-link intermediate portion. The second inner link plate comprises a third inner-link end portion, a fourth inner-link end portion, and a second inner-link intermediate portion. A first inner-link end edge has a first chamfer extending about the first inner-link center axis such that a part of the first chamfer is disposed in a first circumferential area defined from a first inner-link longitudinal centerline to a first reference line when viewed in an axial direction of the first inner-link center axis. The first circumferential area is smaller than 14 degrees.
