Description

DID Enduro Chain – Made in Japan

520ERV3 Enduro and Desert Racing Champion =  Low Weight, Low Friction X-Ring

520VT2 Enduro and Trail Riding = Narrow X-Ring Chain

520VX2 Enduro and Trail Riding = Great value X-Ring Chain

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 compressed points that increase friction. The twisting action of the X-Ring minimizes power loss. X-Ring is a U.S.A. Registered Trademark of D.I.D; Daido Kogyo Co. Ltd. Japan

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.
