Do you need the AXS app to use an AXS groupset? No. But without it, you’ll miss a bunch of bonus features and performance-enhancing firmware updates that will help you get the most out of your AXS groupset, your bike, and your rides.


1) After you’ve paired the components in your AXS groupset together and completed setup and tuning, download the free AXS app from the Apple App Store or Google Play

2) Check that your device’s Bluetooth is turned on (that’s how your device connects to AXS components)

3) Open the app

4) Create a SRAM ID to save bike profiles and help facilitate future service

5) Give your bike a gentle shake to wake up the components (they automatically sleep to save battery power)

8) Press the AXS button on the rear derailleur (the groupset’s ‘Primary Component’) to ensure it is awake. Then press CONNECT in the app to link to the derailleur and assign it to your new bike profile.

You will then be asked to authorize the device when you connect to it for the first time. Follow the prompt to press the AXS button for this authorization.

Then press CONNECT in the app to link to the derailleur and assign it to your new bike profile.
