This is an improved form of O-ring chains. The special shape of the X-ring chain is sealed at four sealing points, so the lubricant cannot escape.

In addition, the X-ring is used as an additional lubricant reservoir. The life of the chain is extended by about 30%. This technique was further developed in the RK XW-Ring chain.
