The Eagle AXS system is completely water and dustproof to the IPX7 international standard. For a mountain biker, it means no hesitation to head out when the weather looks less than ideal.
When washing AXS components, be sure to avoid direct high-pressure washing. Like other components on a bicycle, there are many moving parts with lubrication that can be washed away with aggressive washing techniques.
For more information on how to maintain your SRAM Eagle AXS Components, please see the Eagle AXS Systems User Manual.
