It looks good \u2013 and it is.<\/h2>\n
\n

Thanks to the KMC titanium nitride coating, the X12 for 12-speed drivetrains not only looks fantastic, but its smooth and hard surface also ensures exceptionally smooth shifting and a long service life. Too many teeth? The X series is also available for 8- to 11-speed systems.<\/p>\n<\/div>\n<\/div>\n

    Technologies used<\/h3>\n

    In this chapter, we explain the technologies that the manufacturer uses in this product.<\/p>\n

    \n

    X-Bridge<\/b>
    \nPrecisely chamfered outer tabs with precisely defined angles enable fast and accurate switching operations.<\/p>\n

    Black Tech<\/b>
    \nIt's black and stays black. KMC BlackTech isn't a simple coating, but a surface treatment where the color becomes an integral part of the material. The process is two-stage: first, each individual chain component is treated, and then the process is repeated with the assembled components. This ensures the chain retains its rich black color permanently and is also highly rust-resistant.<\/p>\n

    EPT<\/b>
    \nKMC's latest milestone in rust protection. The non-toxic EcoProTeQ treatment doubles the rust resistance compared to KMC's RB anti-rust treatment. The benefits of this ultra-smooth coating include maximum rust resistance, low noise, and a great appearance.<\/p>\n

    Nickel Plated<\/b>
    \nNickel is an alloying metal primarily used for steel refining. It makes steel corrosion-resistant, increases its hardness and toughness, and is very effective as a rust inhibitor.<\/p>\n

    Ti-N<\/b>
    \nTitanium nitride is a chemical compound of the elements titanium and nitrogen. This ceramic material, typically golden yellow in color, is characterized by its very high hardness and corrosion resistance. KMC's special titanium nitride coating not only looks fantastic, but also has an ultra-smooth surface and is extremely durable.<\/p>\n<\/div>\n<\/div>\n

      Sieht gut aus – und ist es auch Dank der KMC-Titan-Nitrid-Beschichtung sieht die X12 für 12-fach-Schaltungen nicht nur fantastisch aus, die glatte und harte Oberfläche sorgt auch für überaus geschmeidige Schaltvorgänge und eine hohe Lebensdauer.
