SRAM eTAP AXS Battery

The SRAM eTAP battery is compatible with SRAM's XX1/X01 AXS MTB, Red/Force eTAP AXS 12-speed, and Red eTap 11-speed groupsets. It can be used for both the front and the rear derailleur. This way, SRAM has solved the problem of not being able to change gears because of a flat battery: If one of the batteries fails during a ride, simply swap them and continue to ride!
