KMC GO WAX is an advanced dry wax formula that significantly reduces friction, improves shifting, and guarantees optimal performance. It creates a durable micro-coating inside the chain that repels water and resists dirt buildup, providing cleaner and long-lasting performance.

The key aspects include:

• Durability: Once applied, the wax dries to form a protective barrier more resistant than oil-based products.
• Cleaner Operation: Waxed chains attract less dirt, minimizing common wear causes and ensuring smooth operation.
• Simple Maintenance: With minimal dirt buildup, drivetrain maintenance requires less effort. Reapplying wax is easy—just use a dry brush or cloth.
• Environmentally Friendly: KMC GO WAX is biodegradable and free from PFAS or harsh solvents, making it a responsible choice for the chain and the environment.

Innovation is at the core of our series, promoting the shift toward a future where all our products are free from petroleum-based lubricants.
