Drive Chain Gold & Black 420-104L APE100/XR80R

By increasing the thickness of the link plates compared to standard products, the strength is increased by approximately 1.2-1.3 times (compared to SP Takegawa).
Furthermore, it is the strongest 420 series drive chain, equipped with SDH treatment and solid bushings.
SDH Treatment
The cause of chain stretch is the wear of the pins and bushings.
When fine, hard, harmful particles such as sand and dust enter between the pins and bushings, they accelerate chain wear, cause vibration and noise, and shorten the chain's lifespan.
In such cases, D.I.D.'s SDH treatment demonstrates its effectiveness.
SDH treatment forms an extremely hard film on the surface of the pins, and this film has an internal structure with further high-hardness carbides dispersed within it.<
Therefore, even if hard foreign particles enter between the pins and bushings from the outside, it prevents chain wear.
Solid Bushing
This is a highly wear-resistant roller chain that adopts rigid solid bushings with a seamless, smooth surface and excellent roundness.
Solid bushings reduce the barrel-shaped deformation of the bushing that occurs when it is pressed into the link plate, forming an optimal contact bearing surface between the pin and bushing.
