X01 is the quietest, strongest and most wear-resistant chain in the world. This Sram chain uses the all-new Eagle power lock chain connector with Flow Link technology to provide better chain-guiding and increase the longevity of the chain. Hard chrome treatment technology boosts the X01 Chain's optimal performance life.
Each link in the X01 Eagle Chain features a smooth radius with no sharp edges or chamfers to yield a significant reduction in noise, friction, and wear on chainrings and cassette cogs. This design also allows for a flatter plate which boosts overall strength.
