DID STANDARD CHAIN 428HD/134 OPEN CHAIN WITH SPRING LINK
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 428H, the 428HD 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.
Compared to standard chain 428D, the 428HD is reinforced by thicker tabs and therefore has a significantly higher tensile strength.
– 20-50% higher wear resistance compared to the DID 428HD
– strengthened construction
