RK Chains are
engineered to provide an increase in wear life, tensile strength and overall
performance.
RK's
"RX-ring" features an X-shaped seal. The "RX-ring" has two lubrication pools and
contact lips versus the single contact lip/pool design of a regular o-ring
chain. RK "RX-ring" technology offers less torsional friction, increased
high-stress performance and 30% longer wear life compared to standard o-ring
chains. All o-ring chains are backed by RK's unbeatable 20,000 mile warranty.
