DID D.I.D 420 Nz3 Super Non O Ring Chain Connecting Master Link

D.I.D's exclusive SDH (Super DH) pin treatment is the secret behind the superior performance of the NZ Series chains. This high-tech pin treatment forms an extremely hard chromium carbide layer on the pin's surface while maintaining a soft inner core. SDH treated pins have extreme impact strength while maintaining outstanding shock absorption. This treatment creates a chain with anti-oxidation properties and superior wear resistance against invasion of hard foreign materials.
