D.I.D ‘X’ Ring Drive Chain – 530 Pitch VX
Higher wear resistance
Patented X-ring construction
Keeps dirt out and lubrication in
D.I.D’s patented X-ring construction reduces friction by twisting between the side plates instead of squashing. Normal O-rings and other manufacturers modified O-rings have squashed points that increase friction. The twisting action of the X-ring disperses the pressure and minimises power loss.
