This is an improved form of the O-ring chains. Due to the special shape of the X-rings the chain is sealed at four sealing points, the lubricant can not escape. In addition, the X-ring serves as an additional lubricant reservoir. The life of the chain is extended by about 30%. This technique has been further developed into the XW ring chain at RK.
