The KMC X12 BlackTech Pre-Waxed Chain combines KMC’s proprietary BlackTech surface treatment with the performance benefits of KMC GO Chain Wax applied at the factory, delivering a drivetrain-ready chain straight from the box. The BlackTech two-step process integrates the black finish directly into the material of each component - first individually, then again post-assembly - ensuring the chain stays black and maintains superior wear resistance throughout its service life. Pre-waxed with KMC’s advanced dry wax formula, this chain offers reduced friction, cleaner shifting, and significantly less dirt adhesion compared to oil-lubricated alternatives, extending service intervals across the entire drivetrain.
