DID Chain
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.
Up to now, the rolls of sheet metal strips have been wound, resulting in
a seam 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 the 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 428H Strengthened

Sprockets
Made from carefully selected - top quality carbon steel and heat treated
as needed to offer superior performance longer wear life withstand heavy
shock loads and resist abrasion.
Made to precise specifications these sprockets provide excellent chain
fit and performance.
For special applications a variety of different materials and finishes
are used such as stainless steel nickel plated black oxide and zinc
plated.
