SX12SL Diamond chain. The surface coating of the chain adopts the extremely hard synthetic material TiCN (titanium nitride), which is usually used as the coating of cemented carbide structures such as titanium alloy and steel to improve the surface properties. It has the highest lubricity of all tin coatings, which is equivalent to the unique properties of natural diamond. It has low friction coefficient, high hardness and high corrosion resistance.

The SX12 12-speed chain demonstrates the SUMC design's ability to focus on retaining the components of the top chain's many technological advancements. Both inner and outer panels feature chamfered edges for improved shifting and chain articulation. In addition to performance features, SUMC's mushroom riveting technology increases the strength of the pins and makes the chain stronger. SX12 also has a titanium nitride plated surface for improved wear and corrosion resistance. The actual test stable service life is more than 6000 kilometers! The SX12 actually weighs 264 grams (uncut/126 links and lacks link connectors) and costs 2/3 the price of other manufacturers' high-end 12-speed chains. A true balance of performance, weight, strength and price. This makes the SUMC SX12 Silver one of the chain choices for SRAM and Shimano 12-speed drivetrains.
