Many parts are cross compatible between SRAM RED, Force, and Rival eTap AXS such as: 12-speed Flattop chains, 12-speed cassettes from 10-28T all the way up to 10-36T, 1x cranksets, 2x cranksets (be sure to use the correct wide spindle crankset with the wide version front derailleur), shifter controls, and power meters.
See the AXS Components Compatibility Map in the "Compatibility Map" section of the SRAM Service Site to learn more.
