Chain kit RK XSO
This is an improved form of the O-ring chains.
The special shape of the X-rings seals the chain at four sealing points,
the lubricant cannot escape.
The X-ring also serves as an additional lubricant reservoir.
The service life of the chain is extended by about 30%.
This technology was further developed at RK to the XW-ring chain.
