D.I.D 520ZVM-X Chain X-ring

This fantastic 520ZVM-X X-ring chain is for use with road bikes up to 1000cc.

A heavy duty gold x-ring seal rigid street chain. Traditionally, tensile strength has been the benchmark indicating the overall strength of a chain but tensile strength is only a laboratory static measurement of a chain’s fracture point. Rigidity, on the other hand, is the chains tolerance to withstand forces that occur in the real world, notably the type that riders experience.

Increased rigity means better power transfer from the engine to the ground, greater resistance to stretching under load and overall improved performance that meets the demands of high-power bikes and their riders.
