The RK Chain factory has made a running production upgrade to their best selling 520XSO chain. The new upgrade GBXSO and non-gold XSO chains features RK's proprietary 'RX-Ring' seal design and is offered in 520, 525 and 530. All versions are available in either gold/gold or standard steel color. Viewed in cross-section, the RK 'RX-Ring' has two lubrication pools and seal points versus the single seal point/pool design of a regular O-ring chain. RK's new GBXSO chains offer quality, performance and unbeatable value, for all but the most demanding high performance application.
