D.I.D's PATENTED X-Ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers' modified O-Rings have squashed points that increase friction. The twisting action of the X-Ring disperses the pressure and minimizes power loss.
The X-Ring's four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring. X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain.
Sprockets are 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.
