D.I.D 520MX Gold Racing Chain

This chain has the highest tensile strength and SDH pin technology.

For rough and muddy conditions - This super-strong chain is the one you can depend on to handle the toughest race.

SDH Pin - Extreme Impact Pin Strength:

• SDH pin treatment creates an extremely hard Chromium Carbide Layer on the pin's surface. But at the same time, the inner core is maintained soft to absorb shock loads of extreme jumps, etc.

Solid Bush - Cold-Formed High-Precision Bushing:

• Solid Bushing chains have a high wear-resistance. The cold-formed solid bushings have a smooth seamless surface with complete roundness.
• Solid bushing = longer chain life

This chain has 120 links.
