RK - 520XSO - Road Bike Chain

112 or 120 Links

RK's "RX-ring" chains feature an X-ring shaped seal. Viewed in cross-section, the "X-ring" has two lubrication pools and seal points versus the single seal point/pool design of a regular o-ring chain. "RX-ring" technology offers less torsional friction, increased high-stress performance, and a 30% longer wear life compared to standard o-ring chains.

Note

•  Recommended Chain Length is a based on OEM gearing and chain size. May require additional links or cutting if stock gearing has been altered.
