Bike Chain 5/6/7/8 Speed

With the development of ZONKIE's chain manufacturing for many years, we have developed a revolutionary technology.

Provides the hardest hardening foundation with extremely high hardness and self-lubricating properties.

The durability of the balance chain and other transmission components is a fundamental task of ZONKIE. The hardening of the ZONKIE 5/6/7/8-speed bicycle chain does not affect the wear of the cassette and sprocket. Friction-free lubrication helps prevent strain and wear on the drive train components.

Due to its excellent elongation resistance, chain life is greatly increased based on advanced durability enhancement treatment.
