Link Chain Did Ert-2 Gold

All the chains DID had SDH exclusive treatment; best treatment means superior performance of the DID chains. This high-tech treatment consists of a surface layer of carbide/chromium particularly hard and a soft inner core for better mechanical resistance to shocks, torsions and violent tractions to whom pins are subjected. This treatment provides high resistance to external agents as water, mud, degreasing agents, etc. and high mechanical strength of use.
