The heart of it all

If your bike is AXS-equipped, you have at least one rechargeable SRAM AXS battery. Capable of powering a whole host of AXS components, these tiny power units are interchangeable between parts on your bike, easily swappable during a ride, and fully rechargeable in an hour or less. The same battery is compatible with front and rear AXS derailleurs, Eagle AXS derailleurs, Reverb AXS seatposts, and Flight Attendant suspension.

  • Do I need a spare?

    For such a small package, an AXS battery packs a big punch in terms of power, so why not have an extra on hand in case of emergency. Toss one in your tool roll, bar bag, or pocket. You'll hardly notice it's there...it's only 24 grams after all.

  • What about washing

    Your AXS system is completely waterproof, making washing your bike easy. Remove your batteries, reinstall those red things, and wash away without worry.

  • Do I need to stick with the SRAM brand?

    While inexpensive generic options are tempting online, they are not worth the risk. Genuine SRAM parts are designed and tested with a priority on safety and optimal performance.
