SRAM eTap AXS User manual

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.

SRAM Rider Support team via the SRAM Contact form.

AXS App Compatibility and Supported Functions
Can I customize SRAM RED eTap 11-speed shift actions and drivetrain settings with the AXS
App?
No. SRAM eTap 11-speed front and rear derailleurs cannot be connected to the AXS App. Customizing shift
actions and drivetrain settings requires a complete eTap AXS or Eagle AXS system.
Can I use the SRAM AXS App to view battery levels of RED eTap 11-speed derailleurs?
No. SRAM RED eTap 11-speed front and rear derailleurs cannot be connected to the AXS App. The battery
level is displayed by the component’s LED when pressing the function button or performing a shift.
View the Battery Overview section of the eTap Systems Manual or eTap HRD Systems Manual for more
information.
Can I create a bike profile in the SRAM AXS App when combining eTap 11-speed derailleurs
with eTap AXS shift-brake levers or BlipBox?
No. SRAM eTap 11-speed front and rear derailleurs cannot be connected to the AXS App. Bike Profile
creation is only possible with a complete eTap AXS or Eagle AXS system.

How-to
How do I pair SRAM eTap AXS shift-brake levers or an eTap AXS BlipBox to eTap 11-speed
derailleurs?
SRAM RED and Force eTap AXS shift-brake levers or the eTap AXS BlipBox with firmware version 2.29.4 or
later can be paired with RED eTap 11-speed front and rear derailleurs using the RED eTap pairing process.
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.
Follow the instructions below to check the firmware version of your eTap AXS shift-brake levers or eTap AXS
BlipBox before completing the SRAM RED eTap pairing process.
HOW TO CHECK AND UPDATE FIRMWARE
1) Open the AXS App and select one of the following.
•[OFF THE GRID / BLUETOOTH ACCESS] to continue as a guest.
•[SIGN UP] to create a new account.
•[LOGIN] if you already have an account.
2) Wake the eTap AXS shift-brake levers or the eTap AXS BlipBox by pressing the component’s AXS button.
3) Ensure that Bluetooth is enabled on your mobile device and select [SEARCH FOR PARTS].

4) Select a component that appears in the list. Allow 5-10 seconds for the AXS App to connect to the selected
component.
5) If firmware version 2.29.4 or later is not installed, or an update is available, select [NEW FIRMWARE
AVAILABLE]
6) Select [INSTALL].

7) Press and release the component’s AXS button to begin the firmware update. The component’s orange/amber
LED will flash rapidly, and the app will display the update progress.
TECH TIP:If the update progress does advance within 30 seconds of pressing the component’s AXS
button, force quit the app and attempt the process again.
8) When the update completes, select [CONTINUE]. Repeat the firmware update process with the remaining
eTap AXS shift-brake lever. If using an eTap AXS BlipBox, continue to step 9.
9) Complete the SRAM eTap pairing process to pair your RED or Force eTap AXS shift-brake levers or eTap
AXS BlipBox to your RED eTap 11-speed derailleurs.
