Great chain on a great bike!
Smooth riding, best quality chain.
Made in Taiwan, which I support the most..
These chains are absolute workhorses! I’ve been running them for years and can say, they are the longest lasting chains on the market. One thing though. I will no longer buy them from any other source. I’ll only buy directly from KMC from now on. There are too many counterfeits out there!

The latest milestone of KMC in rust protection. The non-toxic EcoProTeQ treatment doubles the rust resistance compared to KMC‘s RB anti-rust treatment. The advantages of the very smooth coating are maximum rust resistance, low noise and a great look.
NICKLE PLATED COATING
Nickel is an alloying metal that is mainly used for steel refinement. It makes steel resistant to corrosion, increases its hardness and toughness and is very effective as a rust protection.
