DID CHAIN ERVT G&G 520X120 XRING
ID 520 ERVT CHAIN X-RING 118 LINKS
If your bike has slim clearances designed for traditional, non-sealed drive chains, DID’s ERVT is a great choice for getting the extended durability of their X-Ring chain in a narrow package. The ERVT uses DID’s patented X-Ring design to hold lubricant inside the chain assembly and reduce friction points that occur in every link. This makes the ERVT specifically geared for the harshness of off-road riding with 1.5 to 2 times the lifespan and half the power loss of competing O-ring and modified O-ring designs. The ERVT chain is plenty robust with a tensile strength of 8,440 pounds and is recommended for any bike 500cc or under. So if your bike fits narrow, non-o-ring chains but you want the durability and ease of a sealed chain, pick up the DID 520 ERVT Narrow Enduro Racing X-Ring Chain for everything but width.
