Tools Required
- Torque wrench [paid link] (up to 300Nm)
- 5mm and 6mm Allen wrenches [paid link]
- Shock pump with gauge
- Suspension fluid (specific to RockShox)
- T25 Torx wrench [paid link]

Installation of the Super Deluxe Ultimate DH Rear Shocks
Installing the Super Deluxe Ultimate DH [paid link] rear shock requires precision and care. Follow these steps for a secure and effective installation.
- Prepare the Bike Frame
Ensure your bike is stable on a repair stand and that the rear wheel is removed for easier access to the shock. - Remove the Old Shock (if applicable)
Use a T25 Torx wrench [paid link] to remove the shock mounting bolts on both ends of the rear shock. Make sure to carefully support the shock while loosening the bolts. - Install the Super Deluxe Ultimate DH Shock
Position the new shock onto the shock mount on your frame. Align the shock’s eyelets with the mounting holes. Insert the mounting bolts through the shock’s eyelets and tighten the bolts to the recommended torque value (usually around 150Nm for the shock mounts, but refer to the manufacturer’s guidelines). - Reattach the Rear Wheel
After the shock is securely installed, reattach the rear wheel, ensuring that all components are correctly aligned. - Check for Proper Mounting
Double-check that the shock is mounted correctly, with no misalignment or interference from the frame. Ensure the shock travel matches the frame’s design for optimal performance.
Adjustment of the Super Deluxe Ultimate DH Rear Shocks
Fine-tuning your suspension is essential to achieve the best performance based on your riding style and conditions. The Super Deluxe Ultimate DH offers various adjustments to personalize your ride.
Rebound Adjustment
Rebound damping controls how quickly the shock returns to its extended position after compression. For a downhill setup, you typically want slower rebound to maintain control on rough terrain.
- Clockwise to Slow: Turn the rebound knob clockwise to slow the rebound, which is ideal for fast, rough descents.
- Counterclockwise to Fast: Turn the rebound knob counterclockwise to speed up the rebound, which may be better for smoother tracks.
Compression Adjustment
The compression dial helps control how the shock responds to small impacts. This is crucial for downhill riding, where you need both stability and responsiveness.
- High-Speed Compression: This controls how the shock behaves under fast, hard hits. Set this to your preference depending on the trail conditions.
- Low-Speed Compression: Adjust this dial for handling smaller bumps and impacts. Lower settings will allow more movement, while higher settings provide more resistance.
Sag Setup
Set your sag to around 30% of the shock’s total travel. To do this, use a shock pump to adjust the air pressure in the shock and then sit on your bike. Measure how much the shock compresses when you are in riding position, and adjust the air pressure as necessary. This setting is vital to ensure the shock performs optimally during aggressive downhill riding.
Maintenance of the Super Deluxe Ultimate DH Rear Shocks
Regular maintenance is essential to maintain the performance and longevity of the Super Deluxe Ultimate DH shock. Follow these steps to keep your shock in top condition.
- Clean the Shock After Each Ride
After riding in muddy or dusty conditions, clean the shock with a soft cloth or towel. Avoid using harsh chemicals, as these may damage the shock’s seals and finish. - Check for Leaks
Periodically check for oil leaks around the shock’s body and eyelets. If you notice any oil or air leaks, it may be time to replace the seals or service the shock. - Lubricate the Shock Mounts
To reduce wear and improve performance, lubricate the shock mounts with suspension-specific grease. This will help prevent creaking and ensure smooth movement when the shock compresses and rebounds. - Service the Shock Every 50-100 Hours of Riding
Depending on your usage, the Super Deluxe Ultimate DH rear shock should be fully serviced every 50 to 100 hours of riding. This includes replacing the suspension fluid, checking the seals, and ensuring all components are functioning as expected. - Check the Air Pressure Regularly
Use a shock pump to regularly check and adjust the air pressure in the shock. Incorrect pressure can affect performance and lead to premature wear.
Troubleshooting Common Setup Issues
Even with the best equipment, issues can arise. Below are some common problems and solutions for the Super Deluxe Ultimate DH rear shock.
Shock Bottoming Out
If the shock bottoms out too easily, it may be due to insufficient air pressure or improper compression settings. Increase the air pressure or adjust the high-speed compression dial for better bottom-out resistance.
Excessive Rebound
If the shock rebounds too quickly and causes a lack of control, slow down the rebound by turning the rebound knob clockwise. Fine-tuning this will help provide better stability on aggressive descents.
Excessive Sag
If the shock sags too much, increase the air pressure to raise the ride height. Ensure you adjust the sag to 30% for optimal performance.
Customization and Optimization for Better Performance
To get the most out of your Super Deluxe Ultimate DH rear shock, consider customizing the setup based on your personal riding style and preferences. Here are a few recommendations to optimize performance:
- Fine-Tune Compression Settings: If you prefer a plush feel, reduce the compression damping. For more support, increase it to handle rougher trails.
- Adjust Air Pressure for Rider Weight: Ensure the shock pressure is appropriate for your weight. Lighter riders may need less pressure, while heavier riders should increase it.
- Upgrade to a Coil Spring (if compatible): For added performance, especially in extremely rough terrain, upgrading to a coil spring might offer more support and smoother action.
Comparison with Similar Models
When compared to other downhill shock options, the Super Deluxe Ultimate DH stands out for its superior adjustability and robust performance. Here’s how it compares to similar models:
- Fox DHX2: While both the RockShox Super Deluxe Ultimate DH and Fox DHX2 offer similar levels of adjustability, the Super Deluxe offers a slightly more plush feel with better responsiveness on fast descents.
- Ohlins TTX22M: The Ohlins TTX22M provides excellent dampening control but tends to be a bit stiffer compared to the Super Deluxe Ultimate DH, making it less suitable for riders who prioritize a smoother, more forgiving ride.
Overall, the RockShox Super Deluxe Ultimate DH offers a versatile [paid link] and performance-driven shock that excels in downhill environments, with extensive customization options to cater to a wide range of riders.
Understanding Compatibility with Other Drivetrain Components
The Super Deluxe Ultimate DH rear shock is compatible with most modern downhill bike frames and drivetrain systems. However, ensure that your bike’s frame is designed to handle the shock’s travel range and mounting specifications. It is important to double-check the shock’s eyelet dimensions and mounting hardware compatibility with your frame. Additionally, it works seamlessly with most 12-speed drivetrains, offering smooth suspension response even under heavy load.
