DID 520 VX Series Street X-Ring Chain (120)

Half the Power Loss (Compared with Normal O-Ring)
D.I.D’s PATENTED X-Ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The twisting action of the X-Ring disperses the pressure and minimizes power loss.

1.5 to 2 times Longer Wear Resistance (Compared with Normal O-Ring)
The X-Ring’s four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring. X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain.
