Can anyone enlighten me on the cross compatibility between ‘old school’ red etap parts and the new AXS 12 speed parts? I specifically mean the new wireless blips and if they can connect to the blip box/derailleurs, but any tips are appreciated. thanks

the axs blips in question eTap AXS Wireless Blips | EC-BLIP-B1 | SRAM
old school blipbox - eTap BlipBox | ES-EAC-BBOX-A1 | SRAM | Service

With the newest AXS app and the latest firmware the AXS blip box will work with 11- speed Etap.
That’s about it. Wireless blips will not work.
