The SRAM Kette PC RED AXS E1 is a high-performance bicycle chain designed specifically for modern 12-speed SRAM RED AXS drivetrains. Built to deliver crisp, reliable shifting under load, it is engineered for riders who demand maximum efficiency and smooth power transfer on the road. Its construction is optimized for use with narrow, wide-range cassettes and compact chainrings, helping to reduce noise and improve drivetrain feel during both intense efforts and long endurance rides.
This chain is designed to work seamlessly with SRAM’s electronic AXS shifting systems, supporting fast, precise gear changes in all conditions. The outer and inner plate shaping is typically refined to enhance engagement with chainrings and cassettes, while also helping to manage wear over time. A special surface treatment is commonly used on premium chains like this to improve durability and corrosion resistance, making it a smart choice for riders who train and race in varied weather. Whether you are chasing personal bests, racing, or simply want a top-tier road drivetrain, the SRAM PC RED AXS E1 chain is a key upgrade component.
