The KMC XSL Flat Waxed Super Light chains are developed on decades of drivetrain R&D expertise, integrating advanced engineering and manufacturing innovations. Designed specifically for SRAM T-TYPE / Flattop 12/13 speed drivetrain systems, the X-Bridge structure features optimized chamfering and a widened inner bridge to ensure precise, stable shifting across a wide range of gear combinations and chainline conditions. This design enhances overall drivetrain compatibility while improving shifting efficiency and reliability. This light weight version features inner and outer plates with strategic cut-outs and hollow pins without sacrificing durability. Combined with KMC's GO innovative wax-based formula and a specialized wax treatment process, the chain delivers low-friction performance straight out of the box.Nickel-plated coating increases its hardness and toughness and is very effective as a rust protectionCompatible with SRAM's 12-/13-speed AXS drivetrains or Transmission/T-Type drivetrains (Not compatible with other 12-/13-speed systems or older SRAM groups)Thanks to the innovative formula of KMC GO CHAIN WAX, the premium KMC chains treated with their wax from the factory offer high efficiency and unrivaled durabilityWith Double X Bridge construction, these chains increase shifitng precision and shifting speed - Smooth, fast, and accurateRamps are specifically engineered with inner and outer link chamfering to engage with your chain rings and cassettes quickly and provide smooth shiftingFeatures inner and outer plates with mud shedding cut-outs and high strength hollw pins that keep weight to a minimumItem SpecificationsColorSilverDefined ColorSilverDrivetrain Speeds12Drivetrain Speeds13Half Link ChainNoLinks126 KMC XSL Flat Waxed Chain Chains UPC: 766759712167
