Abstract

An inner link plate for a bicycle chain is provided. The inner link plate may have a longitudinal centerline defining a longitudinal direction and comprising a first inner-link end portion including a first inner-link opening having a first inner-link center axis, a second inner-link end portion including a second inner-link opening having a second inner-link center axis parallel to the first inner-link center axis, and an inner-link intermediate portion interconnecting the first inner-link end portion and the second inner-link end portion. The first inner-link end portion may have an extended edge portion extending to be away from the second inner-link end portion in the longitudinal direction.

Description

technical field [0001] The present disclosure generally relates to bicycle chains. More specifically, the present invention relates to inner link plates for bicycle chains. Background technique [0002] Cycling is becoming an increasingly popular form of recreation and mode of transportation. Additionally, cycling has become a very popular competitive sport for both amateurs and professionals. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving the various components of the bicycle. One component that has been redesigned is the bicycle chain. Most bicycles have a drive train that uses a chain to transmit the pedaling action from the rider to the rear wheel. A bicycle chain has a plurality of inner links and a plurality of outer links interconnected in an alternating fashion by a plurality of pins. Typically, each of the inner chains includes a pair of parallel inner plates connected by a pair of paralle...
