DID is an OEM of many Japanese and European brands. Leading racing teams in the road and off-road sports rely on the technology of DID.
As a successor to the tried and tested 420 standard chain, the 420D used a new technology for manufacturing the rollers.
So far, the rolls of sheet metal strips have been wound, resulting in a sewing site and thus a weak point.
Thanks to the new technology, the rolls are made of round material and a sewing area is thus avoided.
