What is the SRAM XX1 Eagle AXS Rainbow Chain built for?

The XX1 Eagle AXS Chain is a high-performance 12-speed chain designed specifically to maximize shifting precision in Eagle Transmission and AXS electronic systems. The unique flat-top-adjacent outer plate geometry and hollow pin construction deliver significantly improved wear resistance on Eagle cassettes and rings compared to previous-generation chains, while keeping weight competitive at the top of the range. The rainbow finish ties the whole build together visually with the XG-1299 cassette and other XX1 Eagle AXS components.

At 126 links, this chain comes ready to size for most builds and uses PowerLock master links for clean, tool-free removal. It is engineered to work optimally with AXS electronic shifting actuation, where precise chain engagement under load matters more than ever. If you are building a full XX1 Eagle AXS system, the rainbow chain is the component that pulls the whole aesthetic together without sacrificing a millimeter of performance.
