The high end chain for 12 speed systems wit hKMC's GO wax. The diamond-like DLC coating reduces friction and brings one of the most durable and efficient chain. DLC 12x is approved for E-Bikes.
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.

DLC technology
KMC's Titanium-Carbon-Nitride coated chains have an extremely hard surface, reducing friction and wear. As a result, they offer excellent shifting performance and a smooth transmission. The high-end pin is another feature to reach the best possible durability.
