The Bonus Button on the hood of the RED AXS shift-brake control provides an auxiliary shift option or can be used for ANT+ device control. Out of the box, the Bonus Button is programmed as a shifter with right set for harder and left for easier. Or, customize your Bonus Button using the SRAM AXS App to swipe between pages on your Hammerhead Karoo or other compatible bike computer.
