Yes! SRAM RED eTap AXS (D1) and Force eTap AXS (D1) shift-brake levers, as well as the eTap AXS BlipBox and the Vuka Shift AXS 90, with firmware version 2.29.4 or later, are compatible with RED eTap 11-speed front and rear derailleurs.
Rival eTap AXS, RED AXS (E1) and Force AXS (D2) shift-brake levers are not compatible with RED eTap 11-speed derailleurs due to differences in their electronic hardware and do not support this firmware feature. See below to distinguish between compatible and incompatible Force shift-brake levers.
COMPATIBLE: Force eTap AXS (D1)
NOT COMPATIBLE: Force AXS (D2)
COMPATIBLE: RED eTap AXS (D1)
NOT COMPATIBLE: RED AXS (E1)
NOT COMPATIBLE: APEX AXS (D1)
NOTE: SRAM RED eTap 11-speed front and rear derailleurs do not require a firmware update to pair with firmware 2.29.4 compatible SRAM eTap AXS shift-brake levers and eTap AXS BlipBox.
