X12 Aurora Waxed Chain

KMC X12 Aurora Waxed Chain 126L

Add a touch of glamour to your bike with KMC's Aurora chain. This professional-level 12-speed chain offers perfect shifting and dynamic propulsion through KMC's X-Bridge technology.

Thanks to the innovative formula of KMC GO CHAIN WAX, the premium KMC chains treated with this wax deliver unmatched durability and efficiency. Unlike oil-based lubricants, waxed chains are less susceptible to dirt build-up, extending drivetrain life and reducing cleaning intervals.

The KMC X-Series is specifically developed with the unique characteristics of Shimano, SRAM, and Campagnolo systems in mind. The precisely chamfered plates of the X-Bridge technology ensure perfect shifting and smooth propulsion in all riding conditions. Many top athletes in professional cycling trust the X Series for its reliability.

• Biodegradable: Free from PFAS and harsh solvents  
• Easy to use: Easy to apply, and the chain does not need to be dewaxed before rewaxing
