Description

Technical Field

[0001] The utility model relates to the technical field of spokes, in particular to a new type of soft rope spoke. Background Art

[0002] With the wide popularization of outdoor cycling, more and more cycling enthusiasts prefer light cycling, which requires the cycling bicycle to be lighter and more durable. There are many components on the bicycle, and the rim spokes are one of the components. One end of the rim spoke is connected to the rim, and the other end is connected to the hub. With the development of society, more and more cyclists have higher requirements for the strength of the spokes and lighter weight. In the market, rigidly connected spokes are used in two-wheeled or multi-wheeled bicycles or electric bicycles, such as steel spokes, aluminum spokes or carbon fiber spokes. Such rigid spokes provide a rigid connection between the rim and the hub during the operation of the wheel and transmit the pedaling power. Using rigid materials as spokes can provide a stable rigid connection, but at the same time, the vibration caused by the operation of the rim will be transmitted to the rider's hands, causing discomfort and affecting the riding experience. When the tension of the spoke approaches the limit of the rigid material, the spoke will deform when subjected to a large impact, ultimately resulting in a weakening of the strength and causing potential safety hazards for cycling. Another problem is that the weight of such rigid spokes is generally heavy, which will increase the weight load of the bicycle and affect the riding speed.
