SRAM eTap / AXS Battery is the power source for the eTap / AXS system. The same power unit is interchangeable between front and rear derailleurs.

It’s Time To Shift Forward. At SRAM, we know that if a technological advancement clutters the experience, it shouldn’t be called an advancement. Because it’s a bicycle. It’s supposed to be simple. To make something elegant to the point where it removes what’s in the way… that’s advancement. That is the standard we held ourselves to while developing our first electronic shifting system; SRAM RED® eTap.
