4. Setup and Installation
The SRAM Flight Attendant Pedal Sensor is designed for integration into a DUB Flight Attendant crankset. Follow these general steps for installation. Refer to your specific crankset's manual for detailed instructions.
- Prepare the Crankset: Ensure your DUB Flight Attendant crankset is clean and ready for sensor installation.
- Insert Sensor Core: Carefully insert the Flight Attendant Pedal Sensor Core into the designated cavity within the crank spindle.
- Install Seal Tube: Place the seal tube over the sensor core to protect it from elements and secure its position.
- Position Expander: Install the expander component, ensuring it aligns correctly with the sensor and crank.
- Secure with Bolt: Use the provided bolt to secure the entire assembly. Tighten the bolt to the torque specifications outlined in your crankset's manual. Overtightening can damage components, while undertightening can lead to sensor malfunction or detachment.
- Pairing: After physical installation, follow the instructions for your SRAM AXS system to pair the pedal sensor with your Flight Attendant suspension components. This typically involves pressing the AXS button on the sensor and other components in a specific sequence.
5. Operating Instructions
The Flight Attendant Pedal Sensor operates as part of the SRAM Flight Attendant ecosystem. Once installed and paired, it continuously monitors pedal activity and rider input, transmitting this data wirelessly to the Flight Attendant control module.
- Automatic Operation: The sensor works autonomously, providing real-time data to inform the Flight Attendant system's automatic suspension adjustments.
- Indicator Light: The sensor features an indicator light (visible in Image 1) that provides feedback on its status, such as power on, pairing mode, or low battery. Refer to the SRAM AXS app or Flight Attendant system manual for specific light codes.
- Battery Life: The sensor is powered by an internal battery. Monitor battery status via the SRAM AXS app.
- AXS App Integration: For advanced settings, firmware updates, and battery monitoring, use the SRAM AXS mobile application.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your pedal sensor.
- Cleaning: Keep the sensor and surrounding crank area clean. Wipe with a damp cloth. Avoid high-pressure washing directly on the sensor.
- Inspection: Periodically inspect the sensor and its mounting for any signs of damage, wear, or loose components.
- Firmware Updates: Regularly check for and install firmware updates via the SRAM AXS app to ensure the sensor operates with the latest features and improvements.
- Battery Charging: Recharge the sensor's battery as indicated by the AXS app or the sensor's indicator light. Use only the charger specified by SRAM.
7. Troubleshooting
If you encounter issues with your SRAM Flight Attendant Pedal Sensor, consider the following troubleshooting steps:
- Sensor Not Responding:
- Check battery level using the SRAM AXS app. Recharge if necessary.
- Ensure the sensor is securely installed and all connections are tight.
- Attempt to re-pair the sensor with your Flight Attendant system.
- Incorrect Data/Performance:
- Verify that the sensor's firmware is up to date.
- Perform a system calibration if available through the AXS app.
- Check for any physical obstructions or damage to the sensor.
- Pairing Issues:
- Ensure all components (sensor, controller, suspension) are awake and within range.
- Follow the pairing procedure precisely as outlined in the SRAM AXS manual.
- Check for interference from other wireless devices.
For persistent issues, contact SRAM customer support or visit an authorized SRAM service center.
