Traditionally, "Tensile Strength" has been used to indicate the overall strength of a chain. But Tensile Strength is only a laboratory static measurement of a chain's "breaking point".
Rigidity, on the other hand, is the ability of a chain to withstand forces that occur in a rider's real world experience. Increased rigidity means better power transfer from the engine to the ground and greater resistance to stretching under load.
D's race proven X-Ring® design delivers overall improved performance that meets the demands of today's high-performance machines. Comes in a Black finish. D's X-Ring chain is designed for high performance motorcycles and Quads.
Their patented X-Ring construction creates a chain that is both low in friction and high in wear resistance. D's sealed chains incorporate uniquely designed seal-rings which seal D.D's special "V" grease in the pin/bushing area and lock dirt out. They are expected to last at least ten times longer, produce 50% less friction and have up to 100% longer wear life than standard chains without significant wear elongation under satisfactory maintenance.
