Understanding the SIDluxe Ultimate Flight Attendant Rear Shock

Before diving into the servicing process, it’s important to understand the function and features of the SIDluxe Ultimate [paid link] Flight Attendant rear shock. This shock uses the Flight Attendant system, which actively adjusts the suspension in real-time based on terrain conditions. It provides on-the-fly adjustments between a firm, efficient setting for climbing and a plush, responsive setting for descending. The SIDluxe Ultimate combines RockShox’s proprietary technologies with this dynamic adjustment system for the ultimate trail performance.

Step 1: Prepare the Rear Shock for Service

  • Remove the Shock from the Bike: Use the 5mm Allen wrench to detach the rear shock from the frame. Be careful not to damage the frame or shock during removal. Place the shock on a clean, stable surface for servicing.
  • Clean the Shock: Wipe down the shock body with a lint-free rag to remove dirt and grime. This will prevent contaminants from entering the shock during the service process.

Step 2: Remove the Air Can

  • Loosen the Air Valve: Using the shock pump, slowly release the air pressure from the shock. Be sure to do this gradually to avoid a sudden loss of pressure.
  • Remove the End Caps: Use the 2.5mm Allen wrench to remove the bolts securing the end caps. These bolts are typically located at both the top and bottom of the shock. Once removed, carefully slide off the end caps.
  • Separate the Air Can: Gently pull the air can away from the shock body. You may need to use a soft, even pull to break the seal. Be cautious not to damage the seals or O-rings.

Step 3: Inspect and Clean the Internal Components

  • Inspect for Wear: Examine the internal components of the shock, including the air sleeve and damper shaft. Look for any signs of wear or damage, such as scratches or worn seals. If necessary, replace any damaged parts with new OEM RockShox components.
  • Clean the Components: Use a small brush to clean the air can and other parts of the shock. Ensure no dirt or debris remains on the components. Be meticulous during this step to ensure the shock remains free from contaminants that could impact performance.
  • Check the Seals: Inspect the oil seals for signs of wear or leakage. If any seals appear damaged, replace them immediately to ensure proper function.

Step 4: Replace the Suspension Fluid

  • Drain the Old Fluid: Place the shock in a vice with soft jaws, ensuring the shock is secure but not damaged. Remove the damper valve and drain the old suspension fluid into a container. Ensure all fluid has been removed from the shock body.
  • Refill with New Fluid: Using the appropriate suspension fluid for RockShox, refill the shock with the correct amount of oil. This is critical for the performance of the shock, so be sure to follow the manufacturer’s specifications.
  • Reassemble the Shock: Once the shock is filled with new fluid, carefully reassemble the shock by replacing the damper valve and tightening any screws. Ensure the shock body and air can are properly aligned before resealing.

Step 5: Reinstall the Air Can

  • Lubricate the Seals: Before reassembling, apply a thin layer of suspension fluid to the O-rings and seals. This helps ensure a proper seal and smooth movement of the shock.
  • Reattach the Air Can: Slide the air can back onto the shock body and press it firmly into place. Reinstall the end caps and tighten the bolts to the manufacturer’s recommended torque setting (usually around 5-6 Nm).
  • Pump the Shock: Using a shock pump, add air to the shock to your desired pressure based on your weight and riding preferences.

Step 6: Final Adjustments and Testing

  • Check for Leaks: Before reinstalling the shock on your bike, check for any air or oil leaks around the seals. If you notice any leaks, recheck the assembly and ensure the seals are properly seated.
  • Test the Shock: Reinstall the shock on your bike and test it by gently compressing it to ensure proper movement. If the shock feels too firm or too soft, make adjustments to the air pressure or damping settings as needed.
  • Adjust the Flight Attendant Settings: The SIDluxe Ultimate Flight Attendant features dynamic adjustment for on-the-fly changes in compression and rebound. Test the shock under various conditions to ensure that the Flight Attendant system is responding correctly.

Step 7: Troubleshooting Common Set-Up Issues

  • Shock is Too Soft: If the shock feels too soft, it could be a sign that the air pressure is too low. Add more air using the shock pump and retest the shock.
  • Shock Feels Too Firm: If the shock is too firm, check that the air pressure is within the recommended range for your weight. Additionally, ensure that the Flight Attendant system is functioning correctly and that there is no obstruction in the system.
  • Excessive Noise: If the shock produces unusual noises during compression or rebound, it may indicate a lack of lubrication or a damaged seal. Inspect and lubricate the seals, and replace any parts that appear damaged.
  • Air or Oil Leaks: Leaks can occur if seals are improperly installed or if they are worn out. Carefully inspect all seals and replace them if necessary. Also, ensure that all bolts are tightened to the proper torque.

Step 8: Customizing for Optimal Performance

  • Fine-Tuning Air Pressure: Adjusting the air pressure is one of the easiest ways to customize the performance of your SIDluxe Ultimate. For more aggressive riding, you may want to run a slightly higher air pressure for a firmer, more responsive shock. For smoother, more technical terrain, a lower air pressure may provide a more plush and forgiving feel.
  • Rebound and Compression Adjustments: The rebound and compression settings can be fine-tuned to match your riding style. A faster rebound setting is ideal for aggressive riders who want quick recovery, while a slower rebound setting is better suited for technical terrain or those who prefer a smoother ride.
