CHAIN SRAM PC-XX1 BLACK 12S 126L RAINBOW

The radius of the links in the Sram XX1 Eagle 12-speed chain is even, and they have no sharp edges or chamfers, which significantly reduces noise, friction, and wear on both the front and rear sprockets. This design also allows for a flatter plate, meaning more consistent chain riveting and greater overall strength. Additionally, the HARD CHROME™ technology extends the chain's optimal service life.
