KMC X12 Waxed 12 Speed ChainPre-Waxed Chain Thanks to the innovative formula of KMC GO CHAIN WAX, the premium KMC chains treated with our wax offer next to high efficiency an unrivalled durability. Compared to oil-based lubricants, waxed chains are less susceptible to dirt build-up – increasing drivetrain life and reducing cleaning intervals. Long lasting: The wax forms a protective barrier that outlasts oil-based products
Less dirt: Waxed chains attract less dirt, minimising the common causes of wear and always ensures a smooth operation
Biodegradable: Free from PFAS and harsh solvents
Easy to use: Easy to apply and the chain does not need to be dewaxed before rewaxing

The Non-Directional design allows maximum compatibility. The Double X-Bridge system on the outer plate is configured with precisely articulated angles for quicker and smoother gear shifting, and quieter riding.
Regarding the specific characteristics of Shimano, SRAM and Campagnolo systems KMC developed a series meeting the highest demands. Precisely engineered, their dynamically chamfered plate angle provides a perfect shifting performance and a smooth transmission.
