STEP 1: 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

STEP 2: 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 or bounce your bike to wake up the AXS system or simply start riding.

TECH TIP: Always use SRAM-branded batteries and chargers to get the most consistent and safe performance from your AXS components.

STEP 3: Learn to shift.

SRAM eTap shift logic makes controlling your bike easier than ever. The drop bar controls arrive with the left controller programmed to move the derailleur inboard to an easier gear, while the right controller moves to rear derailleur outboard to a harder gear.

STEP 4: Better braking.

The hydraulic disc brakes that come on your bike ensure the best power and control for riding in all conditions on any terrain. To get the most out of your new brakes, complete the brake bed-in procedure before your first ride. Bed-in is the process of controlled slowing to gradually heat the braking surface while evenly embedding brake pad material into the disc rotor. Proper bed-in prevents brake noise and allows for consistent performance.
