KMC O-Ring chain 428, ISO 9001, 52 - 80 links

The KMC O-ring chain is a high-performance chain that is designed to be durable.
It is made from a specially alloyed and heat-treated steel.
A special construction and the O-rings in connection with the hardened links prevent a too rapid loss of fat from the chain and thus ensure a longer service life, as well as an excellent durability of the chain (approx. 5-10 times longer than standard chains)
Thanks to the reinforced links, the KMC O-ring chain is suitable for all performance classes.
