General Compatibility
Do SRAM eTap AXS shift-brake levers or an eTap AXS BlipBox work with eTap 11-
speed front and rear derailleurs?
Yes! SRAM RED and Force eTap AXS shift-brake levers, as well as eTap AXS BlipBox, with
firmware version 2.29.4 or later, are compatible with RED eTap 11-speed front and rear derailleurs.
Rival eTap AXS shift-brake levers are not compatible with eTap 11-speed derailleurs due to differences in their
electronic hardware and do not support this firmware feature.
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.
SRAM RED eTap 11 Speed Component Compatibility
Will a firmware update for SRAM RED eTap 11-speed derailleurs be released to enable 12-
speed compatibility?
No, there are no plans to make RED eTap 11-speed front and rear derailleurs compatible with 12-speed. The
first generation of Red eTap front and rear derailleurs are mechanically designed for 11-speed gearing and
incompatible with 12-speed chains, cassettes, and cranksets.
Will a firmware update for SRAM eTap AXS derailleurs be released to enable 11-speed
compatibility?
No, there are no plans to make eTap AXS 12-speed front and rear derailleurs compatible with 11-speed. SRAM
eTap AXS derailleurs are mechanically designed for 12-speed gearing and are incompatible with 11-speed
chains, cassettes, and cranksets.
Can I use Blips and MultiClics when RED or Force eTap AXS shift-brake levers are
paired with eTap 11-speed derailleurs?
Yes! Blips and MultiClics are compatible in this configuration.
Can I install my existing SRAM RED eTap HRD brake calipers onto RED or Force eTap AXS
HRD shift-brake levers?
Yes! SRAM RED eTap HRD brake calipers are compatible with all eTap AXS brake lever assemblies. If replacing
SRAM RED eTap HRD shift-brake levers from an 11-speed system, SRAM RED or Force eTap AXS HRD lever
assemblies can be purchased and connected to your existing SRAM RED eTap HRD brake calipers.
