BICYCLE CHAIN

摘要

A bicycle chain comprises a first outer link plate, a first inner link plate, and a first link pin. The first outer link plate comprises a first end portion, a second end portion, and a first intermediate portion. The first end portion includes a first opening having a first center axis. A first outer-link distance is defined from the first center axis to a first end edge. The first inner link plate comprises a third end portion, a forth end portion, and a second intermediate portion. The third end portion includes a third opening having a third center axis. A first inner-link distance is defined from the third center axis to a third end edge. A second inner-link distance is defined from the third center axis to a third end edge. The first inner-link distance is larger than the second inner-link distance and the first outer-link distance.
