The Cr-V technology can make the pin have the advantages of abrasion resistance, corrosion resistance, oxidation resistance, fatigue resistance, high temperature resistance and so on.

Developed and upgraded mesh belt furnace heat treatment carburizing process, material quality ultra-high stability, to ensure the excellent mechanical properties of the chain.

The chain is strongly pre-tensioned before sell, which can reduce the initial elongation and improve anti-fatigue strength.

The vacuum pump is used to extract air from the oil container, so that the air inside the chain parts is extracted, forming negative pressure, so that the cracks in the parts are filled with wear-resistant grease.

CHOHO bicycle chain is equipped with joint, PPO, ring riveting, ring joint and other joint modes. It not only takes into account the strength, but also adapts to the different needs of customers.

The chain adopts high-quality steel to ensure the consistency and reliability of the product from the source.
