When it comes to high-performance mountain biking, especially for downhill enthusiasts, selecting the right rear shock is crucial. The RockShox Super Deluxe Ultimate DH [paid link] is one of the most sought-after shocks in the market, known for its precise control, superior damping performance, and outstanding durability. In this guide, we’ll explore everything you need to know about the Super Deluxe Ultimate DH [paid link] rear shock, including installation, adjustments, maintenance, troubleshooting common issues, and how it compares with other models in the market.

Installation of the Super Deluxe Ultimate DH Rear Shock

Installing the Super Deluxe Ultimate DH rear shock on your mountain bike is a relatively straightforward process if you follow the correct steps. Proper installation ensures optimal performance and longevity of the shock.

Tools Required:

  • Torque wrench [paid link]
  • 8mm Allen key
  • Shock pump
  • 22mm spanner
  • 2mm Allen key
  • Grease (for mounting hardware)

Installation Steps:

  1. Prepare the bike: Remove the rear wheel and ensure that the frame is clean and free of debris.
  2. Remove the old shock: If you’re replacing an existing shock, use the 8mm Allen key to remove the bolts securing it to the frame. Carefully take out the old shock.
  3. Install the new shock: Position the Super Deluxe Ultimate DH shock onto the frame. Ensure that the mounting holes align with the frame’s shock mount points.
  4. Secure the shock: Insert the shock bolts through the mounting points. Tighten the bolts to the manufacturer’s recommended torque setting using a torque wrench [paid link].
  5. Set the sag: Using a shock pump, adjust the air pressure in the shock to achieve the recommended sag (usually around 30% of the shock’s total travel). Ensure the air valve is securely tightened after adjustment.
  6. Final checks: Double-check the mounting bolts and air pressure. Reinstall the rear wheel and check for smooth movement.

Adjustments and Fine-Tuning for Optimal Performance

To ensure the Super Deluxe Ultimate DH rear shock performs at its best, various adjustments are available. The shock provides multiple options for tuning, allowing riders to customize the ride to their personal preferences and terrain conditions.

Rebound Adjustment

The Super Deluxe Ultimate DH features an adjustable rebound, allowing riders to control the shock’s return rate after compression. To adjust:

  • Turn the rebound knob clockwise to slow down the return.
  • Turn it counterclockwise to increase the speed of the return.

Ensure that the rebound is set correctly to avoid an overly bouncy ride or sluggish rebound that can hinder performance.

Compression Damping

The shock comes with high-speed and low-speed compression damping adjustments. High-speed compression affects how the shock reacts to fast hits like rock gardens, while low-speed compression controls the suspension’s response to slower terrain.

  • Turn the high-speed compression dial for faster or slower rebound from quick impacts.
  • Adjust the low-speed compression to achieve optimal support and control on more gradual terrain.

Air Spring Pressure

Adjusting the air spring pressure to match your rider weight and intended riding style is crucial. Use a shock pump to fine-tune the air pressure in the positive and negative chambers. The shock’s recommended sag setting is typically around 30% of total shock travel.

Maintenance of the Super Deluxe Ultimate DH Rear Shock

Regular maintenance is essential to keep the Super Deluxe Ultimate DH in top condition. RockShox designed this rear shock to be low-maintenance, but periodic care can extend its lifespan and performance.

Cleaning the Shock

After each ride, clean the shock with mild soap and water to remove dirt and debris. Avoid harsh chemicals that may damage the shock’s seals. Use a soft cloth to gently wipe down the shock’s stanchions.

Lubricating Seals

Regularly lubricate the seals to ensure they remain supple and free from debris. Apply light silicone grease to the shock’s body, especially around the seals, to prevent wear and improve the shock’s performance.

Air Pressure and Travel

Check the air pressure every few rides to ensure it remains consistent. Reinflate the shock to the desired pressure if it feels off or if you’ve experienced a significant change in riding conditions.

Full Servicing

Every 50-100 hours of riding, it’s recommended to have a full service of the shock, which includes:

  • Replacing oil and seals.
  • Checking for any signs of wear or damage.
  • Replacing worn-out components if necessary.

This will help maintain peak [paid link] performance and avoid issues like loss of damping control or air pressure.

Troubleshooting Common Set-Up Issues

Even with a high-quality shock like the Super Deluxe Ultimate DH, riders may encounter a few setup or performance issues. Here are some common problems and their solutions:

No Sag or Excessive Sag

  • Issue: The shock may feel too soft or too stiff due to improper air pressure or sag settings.
  • Solution: Recheck the air pressure and adjust to the correct sag percentage (30% travel). If the sag is still off, inspect the air valve for leaks or damage.

Loss of Rebound Control

  • Issue: If the rebound is not functioning correctly, it may cause the shock to either rebound too quickly or too slowly.
  • Solution: Ensure the rebound knob is turned to the correct setting. If the issue persists, consider performing a full service on the shock to check for internal damage.

No Compression Control

  • Issue: The shock may feel overly plush or unresponsive.
  • Solution: Adjust the low-speed and high-speed compression damping settings. If the problem continues, inspect the shock for any leakage or internal damage.

Customization and Optimization for Better Performance

The Super Deluxe Ultimate DH rear shock is already a highly capable component, but with the right customization, it can be further optimized for specific riding conditions. Here are a few ways to enhance your ride:

Customizing Damping Settings

Fine-tuning both compression and rebound can drastically improve the performance of your rear shock. For aggressive downhill riding, consider increasing the low-speed compression for more support and decreasing rebound speed to prevent bouncing.

Fine-Tuning Air Pressure

If you find that the shock feels too stiff or too soft during your rides, fine-tuning the air pressure can provide more precise control. Experiment with slight adjustments to find the right balance between comfort and performance.

Upgrading to the Latest Technology

RockShox occasionally releases new upgrades for their shock models. If you want to keep your Super Deluxe Ultimate DH performing at its peak [paid link], consider upgrading the internal components as new technologies emerge, such as updated seals or improved damping systems.

Comparison with Other Rear Shocks
