- All D.I.D 'ER' chains are designed exclusively for racing.
- 520ERT3 is used by the top factory SX and MX Teams to win races.
- 520MX chain has higher tensile strength for maximum performance and is ideal for muddy and sandy conditions.
- 520VT2 for offroad applications where a sealed chain is preferred, D.I.D's 520VT2 X-Ring® chain provides excellent low friction high performance.
D.I.D's exclusive SDH pin treatment is featured on the 520ERT2, 520 MX, 520DZ and all NZ Series chains. This hi-tech pin treatment forms an extremely hard chromium carbide layer on the pins surface while maintaining a soft inner core.
SDH treated pins have extreme impact strength while maintaining outstanding shock absorption. This treatment creates a chain with superior wear resistance against invasion of hard foreign materials.
