The DID ER chain is exclusively designed for racing, with the 520ERT3 model trusted by top factory Supercross and Motocross teams.

Featuring DID's innovative SDH pin treatment, this technology creates a hard chromium carbide layer on the pin surface while preserving a soft inner core. 

This results in extreme impact strength, excellent shock absorption, anti-oxidation properties, and superior wear resistance against hard foreign materials, ensuring top-tier performance in demanding conditions.
