- The X10-93 features a variety of performance-enhancing technologies and strengthening features, this chain is one of the most durable on the market. 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. * 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
