KMC X12 Waxed 12-Speed Chain, 126 Links, Aurora Blue

KMC X12 Waxed 12 Speed Chain Product Updated The KMC X Series chains are developed on decades of drivetrain R&D expertise, integrating advanced engineering and manufacturing innovations. Designed specifically for Shimano and Campagnolo 12-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. Pre-Waxed Chain Thanks to the innovative formula of KMC GO CHAIN WAX, the premium KMC chains treated with our wax offer next to high efficiency an unrivalled durability. Unlike oil-lubricated chains, wax-treated chains resist dirt and debris adhesion, reducing abrasive wear, simplifying maintenance, and extending the service life of both the chain and the entire drivetrain—ultimately lowering long-term maintenance costs. Long lasting: The wax forms a protective barrier that outlasts oil-based products Less dirt: Waxed chains attract less dirt, minimising the common causes of wear and always ensures a smooth operation Biodegradable: Free from PFAS and harsh solvents Easy to use: Easy to apply and the chain does not need to be dewaxed before rewaxing Specifications Fully compatible with 12-speed derailleur systems using the Shimano standard Waxed with KMC GO Supplied with non-reusable 12x MissingLink Perfect shifting thanks to Double X-Bridge Non-directional Not compatible with SRAM systems Weight: 236 grams (per 110 links) Pin Length: 5.2mm Size: 1/2" X 11/128"" Chain Length: 126 Links
