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.

KMC GO Wax Benefits

  • Long lasting: Once applied, the wax dries to form a protective barrier that outlasts oil-based products  
  • Less dirt: Waxed chains attract less dirt, minimising the common causes of wear and ensuring smooth operation at all times  
  • Biodegradable: Free from PFAS and harsh solvents  
  • Easy to use: Easy to apply, and the chain does not need to be dewaxed before rewaxing  

Please note: Due to the colouring process for the Aurora chains, the colour may not be a perfect match to the image shown

Very bling in appearance, usual quality from KMC. Cleaning has been a little easier than an oiled chain, but so far I have been covering miles in the dry, wipe with a rag, this is not a simple wipe, this is a resistive wipe, then relax top and bottom. Leave the chain to dry, and away you go. Gear changes are smoother initially, but after about 80km I don't feel or hear any difference between a waxed or oiled chain. I have converted both my bikes to wax in the summer and oil in the winter.
