Drive Chain Gold & Black 420-98L Little Cub / CD50 / Cub 100EX

By increasing the thickness of the link plate compared to standard products, the strength is increased by approximately 1.2-1.3 times (compared to SP Takegawa).
Furthermore, it is the strongest drive chain in the 420 series, equipped with SDH treatment and solid bushes.
SDH Treatment
The cause of chain stretch is wear between the pins and bushes.
When fine, hard, harmful particles such as sand and dust enter between the pins and bushes, it promotes chain wear, causes vibration and noise, and shortens the chain's lifespan.
In such cases, the SDH treatment developed by D.I.D demonstrates its effectiveness.
SDH treatment forms a very hard film on the surface of the pins, and this film has even harder carbides dispersed within it.
Therefore, even if hard foreign particles enter between the pins and bushes from the outside, it prevents chain wear.
Solid Bush
This is a roller chain with excellent wear resistance, adopting rigid solid bushes that have a seamless, smooth surface and excellent roundness.
Solid bushes reduce the barrel-shaped deformation of the bush that occurs when it is pressed into the link plate, forming an optimal contact bearing surface between the pin and bush.
