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

The KMC X-Series was developed with the specific characteristics of the Shimano, SRAM and Campagnolo systems in mind. Thanks to precisely chamfered plates, the X-Bridge technology enables perfect shifting and smooth propulsion in all riding situations. The X Series enjoys the trust of many top athletes in professional cycling.

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 ensures a 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.
BlackTech
Is black and stays black. KMC BlackTech is not a simple coating, but a surface treatment in which the colour becomes part of the material. The process is two-step - firstly, each individual chain component is treated and then the process is repeated with the assembled elements. The chain thus permanently retains its rich black colour and is also highly resistant to rust.
