KMC X10 10 Speed Bike ChainThis versatile 10 speed chain features a half-nickel-plated construction, which makes it more than capable of handling all the intensity that’s associated with long days out on the road as well as all-day epics in the mountains. Whatever your riding discipline, this model is equipped with a variety of performance-enhancing technologies and strengthening features, making it one of the most durable on the market.Developed for high-performance, this version’s non-directional design makes it independent of direction, which allows maximum compatibility on mountain bike (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.Features: Material: Half-Nickel-plated, non-directional Use: Road, MTB Speed: 10 speed Number of Links: 122 Size: 1/2" x 11/128" Pin Length: 5.88mm Compatibility: Shimano, SRAM & Campagnolo compatible (Including all 10X MTB systems) Hi-Performance Extremely Durable Manufacturer’s Part Number: K100BTechnologies: Highest Pin Power: Unsurpassed riveting geometry.
