This 10 speed KMC chain is high performing and extremely durable.The Non-Directional design makes it independent of direction which allows maximum compatibility on MTB or Race bikes. With its unique stretch-proof treatment, the durability has been enhanced massively by reducing the attrition between the inner plates and pin. As a result, chain life has been significantly prolonged. The upper bridge forms a slant vault parallel to the tip of tooth movement. This vault shape makes the tooth and chain engage much more precisely.**Silver Nickel-Plated Coating**Nickel is an alloying metal primarily used for refining steel. With corrosion resistance, enhanced hardness, and proves highly effective as rust protection.* 1/2" X 11/128" - 114 Links* Pin length 5,88 mm* Shimano, Sram and Campagnolo compatible (Including all 10X MTB systems)* Half Nickel plated* NON-Directional* Hi-Performance* Extremely Durable
