DID 520 VX 118 Links (O-rings) ChainRef : DID520VX118 / 533051181

DID presents its 520 VX chain:

• Thanks to its many years of MX experience, DID has developed the VX chain, which is both lighter and stronger, with a new design of X-ring joints that are more resistant to wear
• The VX chain is used by the best factory teams in SX and MX
• The special treatment of the roller axles, exclusive to DID and known as SDH, is the secret of excellent performance; ideal in mud
• The revolutionary SDH treatment forms an extremely hard carbide/chromium layer on the surface of the pins, while maintaining a soft core inside
• SDH-treated axles deliver high impact strength but also remarkable shock-absorption capacity
• SDH treatment produces a chain with superior wear resistance and anti-oxidation properties, which remains high-performing despite multiple external pollutants
• Silver color
