Abstract: Provided is a rim spoke, including a spoke rope and nipples. Mounting heads are fixedly sleeved on both ends of the spoke rope; through mounting holes are formed in the nipples; the nipples are fixedly sleeved on the mounting heads by means of the mounting holes; and the spoke rope is made of a textile fiber material. When the textile fiber spoke rope in a high tension state is subjected to a heavy impact, part of an impact force is cushioned due to the flexibility and strength margin of the spoke rope itself, so that the original characteristics of the spoke rope can still be kept under an extreme impact force without irreversible deformation, thereby reducing riding failure rate of riding, ensuring the riding safety, reducing the daily maintenance requirement of a wheel, and reducing costs.
