Bike Master 197371 530 x 108 BMXR X-Ring Chain, Natural

Ideal O.E. replacement Q4 Sealed Chain (Q4 seal-ring chain) offers 1.5 to 2 times longer wear resistance than regular O-ring chains. Each refined component designed with computer analysis provides higher tensile strength. Specially controlled heat treatment means tougher material, more durability. Q4 seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and fatigue strength. Q4 seal ring offers less friction, which leads to less power loss - almost half of that of standard O-ring chain. Round rivet head offers superior rigidity over 2 or 4-point (quad-staked) riveting. Includes rivet link.
