Installation of the SIDluxe Ultimate Flight Attendant
Tools Required:
- Torque wrench [paid link]
- 5mm and 6mm Allen keys [paid link]
- Suspension pump (for air spring pressure)
- Shock pump (for damping pressure)
- A clean rag or towel for maintenance
Step-by-Step Installation Process:
- Remove the Existing Shock:
- Begin by safely removing your current rear shock from the mountain bike frame. Use a 5mm Allen key to remove the bolts securing the shock in place.
- Prepare the Frame for New Shock:
- Clean the shock mounting areas on both the frame and the shock. Apply a light layer of grease to the mounting points to prevent creaks and ease future removal.
- Install the SIDluxe Ultimate [paid link] Shock:
- Align the SIDluxe Ultimate [paid link] Flight Attendant with the mounting points on your frame.
- Secure the shock by inserting the bolts through the mounting hardware, tightening them with the appropriate torque (typically between 8-10 Nm, check your specific model’s manual for details).
- Adjust the Air Pressure:
- Use a suspension pump to adjust the air pressure in the shock to match your body weight and riding style. Typically, for mountain biking, the pressure should be set around 25-30% of the shock’s total travel as sag.
- Fine-Tune the Damping:
- Once the shock is installed and the air pressure is set, fine-tune the rebound and compression settings using the adjustment knobs on the shock. Start with the recommended settings, and then adjust based on your ride experience.
Adjustment of the SIDluxe Ultimate Flight Attendant
The SIDluxe Ultimate Flight Attendant is known for its versatile [paid link] adjustability, allowing riders to fine-tune the suspension for their specific riding style and terrain.
Adjusting Compression and Rebound:
- Compression Adjustment:
- Located on the damper body, the compression knob controls the speed at which the shock compresses under force. To dial in the compression settings, begin with the low-speed compression at the medium setting.
- Adjust the high-speed compression if you’re riding on faster, more aggressive terrain or need more support on rough descents.
- Rebound Adjustment:
- The rebound knob controls the rate at which the shock returns after compression. Set it to a medium setting and adjust to your preference, ensuring that the shock doesn’t return too quickly or too slowly, which can affect overall handling and comfort.
- Flight Attendant Technology:
- The Flight Attendant system automatically adjusts the shock’s compression and rebound based on your riding style and terrain. It uses sensors to determine when to firm up or soften the suspension, offering real-time customization for optimal performance.
Maintenance of the SIDluxe Ultimate Flight Attendant
Proper maintenance is key to ensuring that the SIDluxe Ultimate Flight Attendant continues to perform at its best over time.
Regular Cleaning:
- After every ride, wipe down the shock with a clean, damp cloth to remove dirt, debris, and moisture.
- Check the seals for any damage or wear and apply a small amount of suspension grease if necessary.
Air Spring Maintenance:
- Check the air pressure at regular intervals, especially if you notice a drop in performance. Use a suspension pump to ensure the air spring is always set to the correct pressure for your weight.
- Refill or replace the air canisters as per the manufacturer’s recommendations.
Rebuilding the Shock:
- Every 50-100 hours of riding, it’s advisable to rebuild the shock. This involves draining the oil, replacing seals, and lubricating the moving parts. For riders who aren’t experienced in suspension servicing, it’s best to take the shock to a professional bike shop for this task.
Troubleshooting Common Set-Up Issues
Despite its advanced design, the SIDluxe Ultimate Flight Attendant may occasionally present some issues. Here are some common troubleshooting tips:
Air Pressure Loss:
- If you notice a drop in air pressure, check the valve for leaks. A common cause could be dirt or debris around the valve stem. Clean the valve area and recheck the pressure.
Lack of Adjustability:
- If the shock feels too stiff or too soft despite adjustments, ensure that you’ve set the correct air pressure based on your weight and riding style.
- If the Flight Attendant system is not responding as expected, make sure the sensors are clean and free from debris.
No Rebound Control:
- If the rebound feels either too fast or too slow, check that the rebound adjustment knob is properly set. Over-tightening can sometimes cause the damper to lock out. Reset it to the starting position and adjust incrementally.
Customization and Optimization for Better Performance
The SIDluxe Ultimate Flight Attendant offers various customization options to optimize your riding experience:
Tuning the Flight Attendant System:
- Adjust the responsiveness of the Flight Attendant system by tweaking the sensor sensitivity settings if available. This allows for a more aggressive or more compliant ride based on your preference.
Fine-Tuning Damping Settings:
- For riders who prefer more technical trails, adjusting the low-speed compression and rebound damping can offer better support during steep climbs and descents.
Upgrading the Shock:
- While the SIDluxe Ultimate Flight Attendant is already a high-end option, riders looking for even more performance can consider pairing it with a premium fork like the RockShox SID SL Ultimate to achieve a perfectly balanced front-to-back suspension system.
Comparison with Similar Models
While the SIDluxe Ultimate Flight Attendant stands out in many ways, it’s worth comparing it with other rear shock models to see if it’s the best fit for your needs.
SIDluxe Ultimate vs. Fox Float X2:
- The Fox Float X2 offers exceptional performance and adjustability, but it’s heavier than the SIDluxe Ultimate Flight Attendant. The latter is lighter and incorporates automatic adjustments through the Flight Attendant system, offering more convenience for riders seeking a set-it-and-forget-it solution.
SIDluxe Ultimate vs. RockShox Super Deluxe:
- The RockShox Super Deluxe provides excellent performance for more aggressive riders, but it lacks the advanced technology of the Flight Attendant. If you prefer a shock that adjusts itself automatically, the SIDluxe Ultimate Flight Attendant is the better option.
Compatibility with Other Drivetrain Components
The SIDluxe Ultimate Flight Attendant is designed to work seamlessly with most modern mountain bike drivetrain systems, including 12-speed SRAM and Shimano setups. However, it’s essential to check for clearance and compatibility with your frame, especially when using specific suspension designs or rear triangle geometries.
Integration with SRAM AXS:
- If you’re using a SRAM AXS wireless drivetrain, the Flight Attendant’s automatic adjustment feature is an excellent complement, as it enhances the overall responsiveness of your bike’s suspension, providing a smoother and more controlled ride.
Shimano Compatibility:
- The SIDluxe Ultimate is equally compatible with Shimano’s top-tier drivetrains, including the XTR and XT models. The shock integrates well into these systems, offering a balanced performance that enhances climbing efficiency and stability on descents.
