The SRAM XX1 Eagle 12 Speed Chain has been completely redesigned to offer ultra-smooth, precise, durable and quiet performance. The engineering inside this incredible chain design makes possible a gear range previously found only in 2-chainring drivetrains. This chain's links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear on chainrings and cassette cogs. The XX1 Eagle's design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength.
