KMC GO WAX – cleaner, faster, longer-lasting

• LONG-LASTING EFFECT: Once applied, the wax dries and forms a protective barrier that outperforms oil-based products.
• CLEAN SOLUTION: Less dirt sticks to our waxed chains, minimising the number one cause of wear.
• MAINTENANCE MADE EASY: Thanks to reduced dirt adhesion, your drivetrain doesn’t need to be cleaned as often. Reapplying the wax is very simple – no need to remove the old wax. Clean the chain with a dry brush or a dry cloth, then apply KMC GO WAX, and you’re done.
• ENVIRONMENTALLY FRIENDLY: KMC GO WAX is biodegradable and free from PFAS and harsh solvents.

KMC X12 Black Tech pre-waxed chain

KMC chains feature a very slim design, known as ‘lean construction’. In addition to being lighter in weight, this design offers exceptionally smooth running and fewer chain jams. The Double X-Durability treatment is a process in which all parts of the chain are specially hardened. This treatment makes the pins, in particular, highly resistant to dust and sand and significantly extends the chain’s lifespan. They are extremely lightweight, incredibly durable and very easy to fit with the MissingLink 12.

KMC BlackTech technology is not a simple coating, but a surface treatment in which the colour becomes an integral part of the material. The process is two-stage – first, each individual chain component is treated, and then the process is repeated with the assembled elements. As a result, the chain retains its deep black colour permanently and is also highly rust-resistant.

The chain locks, Missing Links, for the 12-speed chains enable simple and secure installation of the chains. A standard chain tool is required to shorten the KMC chains to the correct length. The new 12-speed Missing Links are not reusable.
