DID is the original equipment manufacturer for many Japanese and European brands. The leading racing teams in
Road and off-road sports rely on DID technology.
DID 420D:
As a successor to the proven 420 standard chain, new technology was used to produce the rollers on the 420D.
Previously, the rolls were wrapped with strips of sheet metal, which created a seam and thus a weak point.
With the help of new technology, the rolls are made of round material, thus avoiding a seam.
- 20-50% higher wear resistance than DID 420
