DID (520DZ-114) Gold 114 Link High Performance DZ2 Series Non-O-Ring Chain with Connecting Link;

D.I.D.'s 520DZ chain is a great value in a light weight, high performance chain designed for trail riding. D.I.D.'s SDH high-tech pin treatment forms an extremely hard chromium carbide layer on the pin's surface while maintaining a softer inner core. SDH treated pins have extreme impact strength while adding outstanding shock absorption. The SDH process creates a chain with superior wear resistance, outstanding anti-oxidation properties and performs well in dusty and muddy conditions.
