X12 – Precision 12-Speed Performance
The standard KMC X12 offers reliable shifting and strong wear resistance for daily riders. Built with KMC’s proven plate shaping and chamfering, it reduces noise and improves drivetrain efficiency across all 12-speed systems. Ideal for riders who want dependable performance at an excellent value.

X12 Gold – Enhanced Durability & Premium Finish
The gold-coated version of the X12 adds an extra layer of corrosion resistance and long-term durability. Beyond its premium look, the finish helps maintain smooth shifting in wet or muddy conditions, making it a favourite among mountain bikers and all-weather riders.

X12 Aurora – Premium Aesthetics With High Performance
The Aurora (oil-slick) X12 brings top-tier performance with a unique multicolour finish. It offers the same strength and smooth shifting as the standard X12, with a visually striking appearance that stands out on any high-end setup.

All X12 variants use KMC’s robust construction for high tensile strength, efficient power transfer, and consistent performance across all 12-speed drivetrain systems.
