What This Product Does

The KMC DLC Series chain transfers pedaling power through a 12-speed drivetrain while using a titanium-carbon-nitride DLC coating to reduce friction and improve surface durability. The chain is factory-treated with KMC GO CHAIN WAX, which helps reduce dirt accumulation compared with conventional oil-based lubrication. This combination is designed to provide smooth running, reliable shifting, and longer drivetrain service intervals.

Benefits

• DLC coating creates an extremely hard surface designed to reduce friction during drivetrain operation.
• Factory-applied KMC GO CHAIN WAX provides a ready-to-use waxed chain without the need for initial waxing at home.
• Wax lubrication is less susceptible to dirt buildup than traditional oil-based lubricants.
• Reduced contamination can help extend drivetrain life and reduce cleaning intervals.
• Hard-coated pins contribute to an above-average service life of the drivetrain.
• Designed for smooth running and consistent shifting performance.
• Suitable for road, MTB, gravel, and cyclocross applications using compatible 12-speed drivetrains.
