DID 520 ERT2 120 links ChainRef : DID520ERT2120 / 533021201

DID presents its chain 520 ERT2:

• The ERT2 chain is used by the best factory teams in SX and MX
• The special treatment of the roller axes, an exclusive DID called SDH, is the secret to excellent performance; ideal in mud
• The revolutionary SDH treatment forms an extremely hard layer of carbide/chrome on the surface of the axes, while maintaining a soft core inside
• The SDH-treated axes have a high impact strength but also retain remarkable shock absorption capacity
• The SDH treatment provides a chain with superior wear resistance and anti-oxidation properties, which remains effective despite multiple external pollutants
• Gold colour
