Through a series of videos and articles, we’ll cover the basics of your Eagle Transmission, from trail-ready tech tips, to harnessing the potential of infinite personalization. Read on to get the most from your new ride.
Check your battery status.
An LED will flash on your derailleur and controller every time you shift, indicating the battery status of each component. You can also press the AXS button on each component to check the status.
• GREEN = More than 25% of battery charge remaining
• RED = Between 10% and 25% of battery charge remaining
• FLASHING RED = Less than 10% of battery charge remaining
Charge your battery.
AXS batteries take an hour to charge and last for approximately 60 hours of riding time, meaning most riders need to charge roughly once a month. To preserve battery life, AXS components go to sleep when the bike is stationary. Shake it to wake it.
When not in motion, Eagle Transmission will go to sleep on its own to conserve battery life. To wake it up, simply grab and go!
Pairing introduces your components to each other with a wireless handshake, so they form a secure and seamless group. If your system is set up and shifting well, it’s already paired.
TECH TIP: Pairing a complete AXS system takes seconds. Also using Reverb AXS? Pair your derailleur, controllers, and seatpost together into a single system for the most customization options.
Eagle Transmission derailleurs feature no adjustment screws, instead the system relies on a few simple specifics to get the perfect setup. Your bike model and chainring size combination have a defined chain length, as well as a specified Setup Key position and Setup Cog that must be used.
You can calculate these specifications using the Chain Length & Setup Key Calculator, which has a database of all bike models that are compatible with Eagle Transmission.
The Chain Length & Setup Key Calculator can be found here, as well as in the SRAM AXS App.
TECH TIP: If you change your chainring size, or adjust your bike’s geometry with a flip-chip, you must verify your new settings in the Chain Length & Setup Key, adjust as necessary, and reperform the derailleur setup process
