RK 520XSO Chain with 116 links fluorescent blue

Are you looking for an affordable, long-lasting performance chain?

Look no further, RK's XSO chains offer less torsional friction and higher high-tension and high-speed performance, providing a durable chain at an affordable price.

All RX-Ring chains have X-shaped seals and improved metallurgy, giving them 7 times more wear life than standard O-Ring chains.
Seen in cross-section, the RX-Ring has two lubrication pools and contact lips compared to the single contact design of a standard O-Ring chain. Giving the chain a longer life gives you more value for your money.
