About The Product
Looking for an affordable, long lasting performance chain? Look no further, RK's XSO chains offer less torsional friction and increased high-stress, high-speed performance providing a longer lasting chain at an affordable price. All RX-Ring chains have "Refined X" shaped seals and improved metallurgy giving you 7 times longer wear life than standard O-ring chains. Viewed in cross section, the RX-ring has two lubrication pools and contact lips versus the single contact design of a standard O-ring chain. Giving the chain a longer life gives you more value for your money.
