As part of their continuing quality improvement program the RK Chain Factory has made a running production upgrade to their bestselling XSO chain line. The XSO chains feature RK's proprietary RX-Ring seal design. Viewed in cross-section the RK RX-Ring has two contact lips and one lubrication pool versus the single seal point/pool design of a regular O-ring chain. RK's XSO chains offer quality performance and unbeatable value for all but the most demanding high-performance application.
