Compatible with all SRAM 12/13-speed derailleurs with flat-top chains Lubricated with KMC GO grease Contains MissingLink Durability: Item no.: BXFLATNP26W Dimensions: 1/2 x 11/128 Color: nickel silver Length: 126 links FLAT-TOP CHAINS SRAM Flat-Top chains are designed specifically for modern 12/13-speed drivetrains and feature a distinctive flat profile. This design allows for a narrower chain while ensuring high strength and durability. Flat-Top chains are only compatible with SRAM 12-speed AXS or Transmission/T-Type drivetrains. They are not compatible with other 12-speed systems or older SRAM drivetrains. Improve your ride with KMC GO WAX Experience the next level of chain performance with our new, advanced dry wax formula. Designed to significantly reduce friction, improve shifting, and ensure optimal efficiency, KMC GO WAX extends drivetrain life by forming a durable microfilm on the chain that repels water and resists dirt adhesion. For cleaner, faster and longer-lasting performance. DURABILITY: Once applied, the wax dries to form a protective barrier that is more durable than oil-based products. CLEANER RUNNING: Our waxed chains attract less dirt, minimizing common causes of wear and ensuring smoother operation. SIMPLE MAINTENANCE: With minimal dirt buildup, your drivetrain requires less maintenance. Refreshing the wax is simple—just use a dry brush or cloth. No degreasing is required, just a simple touch-up with KMC GO WAX. ENVIRONMENTALLY FRIENDLY: KMC GO WAX is biodegradable and contains no PFAS or harsh solvents, making it a responsible choice for both your bike and the environment. Good for your ride, great for the planet We're pioneering change with our premium chain line and are paving the way for a future where our entire chain range will be free of mineral oil-based lubricants. By producing around 5 million chains per year in the X-series alone, we'll soon save around 20,000 kilograms of mineral oil-based lubricants per year. This change is just the beginning. Consider the enormous amounts of oil traditionally used to maintain chains and its impact on our environment. Our wax-based solution not only improves drivetrain efficiency but also significantly reduces the environmental footprint of our products by preventing harmful chemicals from entering our ecosystems.
