DID ERT3 520×120 Gold chain
• D.I.D ER chain is designed exclusively for racing.
• 520ERT3 is used by the top factory Supercross and Motocross Teams.
• D.I.D’s exclusive SDH pin treatment is the secret behind the superior performance of our 520ERT3, 520 MX and all NZ Series chains. This hi-tech pin treatment forms an extremely hard chromium carbide layer on the pins 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.
