GXW series -
Extra Doubled Life Road Chain (XW-ring)
GXW chain is the top grade of RK road chain, assembled with the “XW-ring” technology made of an advanced Nitrile Butadiene composite and features three contact lips and two convex outer stabilizers. This means three lubrication pools to protect against high speed abrasion, extreme heat build up, torsional flex and loss of lubricant. The “XW-ring” provides the user with more than double longer wear life than standard o-ring chains.
