The X12 brings KMC's biggest breakthrough in rust-protection to 12x groupsets. EcoProteQ treatment doubles the rust resistance compared to the RB treatment. This smoother coating also means less noise from the chain, greater performance, maximum rust resistance and a great look.
Double X Durability, unmatched chain life KMC guarantees your satisfaction! EcoProTeQ Anti-Rust technology, NON-Directional Design: assembly of this chain is independent of direction!
EPT Coating
The environmentally friendly EcoProTeQ technology EPT from KMC protects chains against corrosion for twice as long as conventional rust protection, setting a new standard. Each component of every chain link is treated separately with EPT. This means a 100% coating that offers the lowest possible attack by water, salt, and air humidity.
Another characteristic of EPT: The very smooth surface gives chains excellent running qualities. Dirt buildup is minimised in the long term, which means that chain maintenance is significantly relieved.
