LAUNCH CONTROL SETTINGS

In the SRAM AXS app, Time Release or Bump Release can be activated individually, or both can be activated simultaneously. Bump Release overrides Time Release.

Time Release: Time Release controls how long Flight Attendant remains in Launch Control before returning to Auto Mode. The timer starts with the first pedal stroke. Time Release will be overridden if Bump Release is activated and a bump deactivates Launch Control first.

In the SRAM AXS app, turn Time Release on and set Released Time to the preferred duration. The suspension will stay in the LOCK suspension position from the first pedal stroke through the set Locked Time. Flight Attendant returns to Auto Mode when the Release Time selected is reached.

Bump Release: Bump Release determines what bump size will deactivate Launch Control and return to Auto Mode. Bump Release sensitivity can be set to control when Launch Control will deactivate.

In the SRAM AXS app, turn Bump Release on and move the Bump Release sensitivity slider to the preferred setting to override Time Release (if activated) and deactivate Launch Control.

Refer to the SRAM AXS app for the latest Launch Control app screen interface.

After Launch Control settings have been set in the SRAM AXS app, Launch Control is activated at race start by pressing the assigned AXS controller button, or the + button on the fork Control Module, down for five seconds.

When Time Release is enabled, all five LEDs will pulse red slowly until pedaling begins, and will increase in speed once pedaling begins and the countdown timer starts.

When only Bump Release is enabled, all five LEDs will pulse red twice quickly until a bump is contacted, then Flight Attendant returns to Auto Mode.

When Safe Mode has been activated, the OPEN, PEDAL, and, LOCK position LEDs will illuminate and pulsate yellow and suspension Position switches to OPEN.

The Flight Attendant system enters Safe Mode when the battery level of the Fork Control Module or Rear Shock Module has reached a low state, or if a battery is missing from the fork or rear shock.

Install a fully charged battery to return to Auto Mode.

Safe Mode (OPEN) may also be activated if communication with the rear shock is lost due to its sleep (off) cycle.

Wake the rear shock with movement to restore communication.

If three yellow LEDs illuminate and pulsate, Safe Mode has been activated.

Settings cannot be adjusted in the SRAM AXS app when Safe Mode is activated.

Safe Mode cannot be exited until the triggering issue has been resolved.

Refer to the table below to troubleshoot and restore function.

CAUSE:

• Control Module battery has reached a low charge level.

• Rear Shock Module battery has reached a low charge level.

CORRECT: Press AXS button, check LED color. If flashing red, battery has reached a low charge level. Replace battery with fully charged battery.

VERIFY: Wake components and confirm Control Module LED pulses green, and Auto Mode has been activated.

PREVENT: Check battery levels before each ride and charge or replace batteries as needed.

CAUSE:

• Control Module has lost communication with rear shock.

a) CORRECT: Confirm rear shock SRAM battery is installed. Install SRAM battery.

b) CORRECT: Rear Shock may be asleep (off). Move bicycle to wake (on) the rear shock.

VERIFY: Wake components and confirm Control Module LED pulses green, and Auto Mode has been activated.

a) PREVENT: Confirm SRAM battery latch is closed correctly.

b) PREVENT: Move bicycle to wake rear shock before using Flight Attendant.

The Flight Attendant Control Module will enter Search Mode and cycle through all five yellow LEDs if the Control Module is searching for a Pedal Sensor, Flight Attendant compatible SRAM or Quarq MTB power meter, or a Flight Attendant equipped E-Bike (as a cadence sensor).

Connectivity with Flight Attendant can be confirmed in the SRAM AXS app.

For a bicycle equipped with a Flight Attendant compatible SRAM or Quarq Power Meter, rotate the crankset 360 degrees backward to wake the power meter. Refer to the SRAM AXS app for more details.

For a Flight Attendant equipped E-Bike, turn the bicycle on and wake all Flight Attendant components. Refer to the SRAM AXS app for more details.

When the Pedal Sensor, Flight Attendant compatible SRAM power meter, or Flight Attendant equipped E-Bike has been detected, the OPEN green LED will illuminate.

To activate Manual Mode and begin the Calibration process, press and hold the Menu button until the OPEN suspension position LED is red.

OPEN is the default Manual Mode suspension position when Flight Attendant is activated for the first time.

If Search Mode persists, Manual Mode can be activated for the duration of the ride with a press and hold of the Mode button.

Damper Error Mode - Fork

Flight Attendant will alert you if there is a fork Control Module hardware malfunction. To resolve this issue, remove the SRAM battery from the fork Control Module and reinstall it. The Control Module will re-home itself and set the compression damper to the default OPEN position. If the Control Module repeats the Fork Damper Error Mode alert after installing the SRAM battery, attempt to remove and reinstall the Control Module as instructed in the 2022+ Flight Attendant Service Manual: Pike Lyrik ZEB (Control Module Installation section) or the 2024+ SID SL SID Service Manual (Control Module Installation section). If the Control Module repeats the alerts after reinstalling the Control Module, contact SRAM Rider Support for more information.

Damper Error Mode - Shock

Flight Attendant will alert you if there is a Rear Shock Module hardware malfunction. To resolve the issue, remove the SRAM battery from the Rear Shock Module and reinstall it. The Rear Shock Module will re-home itself and set the compression damper to the default OPEN position. If the Rear Shock Module repeats the alert after installing the SRAM battery, contact SRAM Rider Support for more information.

Flight Attendant is ready to operate when fully charged batteries are installed, pairing and calibration have been completed, Settings have been selected, and the front and rear suspension have been set up properly.

When the system 'wakes up' from bicycle movement, Flight Attendant is activated and the bicycle is ready to ride. Switch Modes as desired with the Control Module or the AXS Controller.

Make any necessary suspension setting adjustments after a few rides to refine the suspension setup.

Use the SRAM AXS app for additional system details, to customize settings, or to make further adjustments.

Flight Attendant components require periodic cleaning and basic service to maintain proper function.

Before suspension disassembly and service, activate Manual Mode with the Flight Attendant Control Module and set the suspension to the OPEN position using the (−) or (+) button.

Compress the suspension fork and rear shock to confirm each damper is in the OPEN position and compresses freely.

Remove the SRAM batteries from each suspension component and install the battery blocks before service.

Consult the Flight Attendant suspension fork and rear shock service manuals at www.sram.com/service for service interval schedules, procedures, and further details.

It is recommended that you periodically clean your Flight Attendant components.

Use a damp cloth to wipe off any dirt and debris. Clean the components with soap and water only. Rinse thoroughly with water and allow the parts to dry.
