This 12 speed KMC chain is high performing and extremely durable.
The Non-Directional design makes it independent of direction which allows maximum compatibility on MTB or Race bikes. With its unique stretch-proof treatment, the durability has been enhanced massively by reducing the attrition between the inner plates and pin. As a result, chain life has been significantly prolonged. The upper bridge forms a slant vault parallel to the tip of tooth movement. This vault shape makes the tooth and chain engage much more precisely.
Gold Ti-N Coating
Titanium nitride is a chemical compound of titanium and nitrogen. The ceramic material of typical golden yellow colour is characterised by extreme hardness and corrosion resistance. This special coating has an ultra-smooth surface, and is extremely durable.
Silver Nickel-Plated Coating
Nickel is an alloying metal primarily used for refining steel. With corrosion resistance, enhanced hardness, and proves highly effective as rust protection.
