Installation of the RockShox Deluxe Ultimate RCT Rear Shock
Installing the Deluxe Ultimate RCT rear shock requires some technical knowledge and specialized tools. Below is a step-by-step guide to ensure a secure and precise installation process.
Tools Required:
- 8mm and 10mm wrenches
- Torque wrench [paid link]
- Shock pump
- 5mm Allen key
- Suspension grease
- Clean rags
- Ruler or caliper for measuring eye-to-eye length
Installation Steps:
- Prepare the Bike: Secure your bike on a work stand to prevent movement during installation. Ensure the rear triangle is stable.
- Remove the Old Shock (if applicable): If replacing an existing shock, use the 8mm or 10mm wrenches to remove the mounting bolts from the old shock. Keep the hardware as it may be reused.
- Apply Suspension Grease: Lightly apply suspension grease to the shock mounting bolts to reduce friction and prevent corrosion.
- Install the Deluxe Ultimate RCT: Align the shock with the mounting holes on the rear triangle and insert the mounting bolts. Tighten them using the 5mm Allen key. Be sure to follow the manufacturer’s torque specifications.
- Adjust the Eye-to-Eye Length: Measure the eye-to-eye length of the shock to ensure it matches the bike frame requirements. If necessary, select the appropriate shock size.
- Check Air Pressure: Attach a shock pump to the valve and inflate the shock to the desired pressure. Check the pressure regularly during rides for optimal performance.
- Final Check: Recheck all bolts to ensure they are tightened to the specified torque. Move the rear suspension through its travel to confirm smooth operation.
Adjustment and Fine-Tuning
The Deluxe Ultimate RCT offers a variety of adjustments to help you customize the shock to your preferences. Proper adjustment of these settings can significantly improve your ride quality.
Rebound Adjustment:
The rebound dial controls how quickly the shock returns after compression. A proper rebound setting ensures the rear suspension does not feel too sluggish or too bouncy.
- Slow rebound is ideal for rough terrain, providing more control.
- Fast rebound suits smoother trails, preventing the shock from feeling overly stiff.
To adjust the rebound, simply turn the dial clockwise to slow it down and counterclockwise to speed it up.
Compression Adjustment:
The Deluxe Ultimate RCT features both high-speed and low-speed compression adjustments. These control how the shock compresses under different forces and can be tuned to improve both comfort and performance.
- Low-speed compression affects slow movements, such as when you climb or corner.
- High-speed compression impacts faster movements, such as when you hit big drops or rough terrain.
Adjust the compression to suit your riding style and the terrain you’ll be tackling.
Air Pressure:
The correct air pressure is crucial for achieving the right amount of support and responsiveness. The Deluxe Ultimate RCT uses air to adjust the shock’s firmness. Use the shock pump to set the air pressure based on your weight, riding style, and terrain.
- Start with a baseline pressure and adjust incrementally. Remember, too much pressure will make the shock feel too stiff, while too little will make it too soft.
Volume Spacers:
The Deluxe Ultimate RCT allows you to add or remove volume spacers to modify the air spring curve. This adjustment can be particularly useful for riders who want to fine-tune their bottom-out resistance and improve mid-stroke support.
Maintenance of the RockShox Deluxe Ultimate RCT Rear Shock
Proper maintenance is essential to keep the Deluxe Ultimate RCT rear shock performing at its best. Regular cleaning, lubrication, and inspection will extend its lifespan and ensure optimal ride quality.
Cleaning:
- After each ride, wipe down the shock with a clean, dry rag to remove any dirt or debris. Be careful not to let water or dirt enter the air spring or damper assembly.
- Use suspension-specific cleaner to gently remove any grease or grime from the shock’s body and components.
- Inspect the shock for any visible damage or excessive wear on the seals.
Lubrication:
Every few rides, apply suspension grease to the shock’s mounting hardware. Additionally, check the shock’s seals and apply light oil to the bushings as necessary.
Inspection:
- Check the shock’s performance by compressing it by hand. Any abnormal stiffness, noise, or lack of smooth motion may indicate internal wear or damage.
- Inspect the air spring for leaks, especially around the valve and seals.
Troubleshooting Common Set-Up Issues
Though the Deluxe Ultimate RCT rear shock is a durable and well-designed component, some common issues can arise during setup. Below are a few problems and their solutions.
Shock Stiffness or Lack of Compression:
If the shock feels too stiff or unresponsive, the air pressure may be set too high. Reduce the pressure gradually until the shock feels more responsive to terrain.
Excessive Bottoming Out:
If you notice the shock is bottoming out too easily on rough terrain, consider adding volume spacers or adjusting the compression settings to provide more resistance in the mid- to end-stroke.
Leaking Air:
Air leakage from the valve or shock body can lead to loss of performance. Inspect the seals and air valve closely for damage. If air leakage persists, it may be necessary to replace the seals or take the shock in for professional servicing.
Customization and Optimization for Better Performance
The Deluxe Ultimate RCT rear shock is highly customizable, allowing riders to tweak the setup to suit their needs. Here are some key considerations for optimizing performance.
Terrain-Specific Adjustments:
For aggressive trails with larger impacts, set the high-speed compression to a higher setting to prevent the shock from bottoming out. On smoother trails, decrease the compression settings to improve comfort and efficiency.
Rider Weight and Riding Style:
Adjust the air pressure based on your weight and riding style. Heavier riders will require higher air pressure, while lighter riders may prefer lower pressure for a more plush feel.
Additionally, fine-tuning the rebound and compression settings will help riders maximize their performance by adapting to their specific riding preferences.
Comparison with Similar Models
When comparing the RockShox Deluxe Ultimate RCT to other rear shocks in the market, a few key features stand out. The Deluxe Ultimate RCT is equipped with both high-speed and low-speed compression adjustments, making it a versatile option for riders who tackle a variety of terrains. Its adjustable air pressure and volume spacers further provide customization, allowing it to adapt to different riders’ needs.
In comparison to the RockShox Monarch Plus, the Deluxe Ultimate RCT offers better performance in high-impact situations and provides more precise adjustments. The Monarch Plus, while a solid option, lacks the fine-tuning capabilities of the Deluxe Ultimate RCT, particularly in terms of high-speed compression and rebound adjustments.
Compatibility with Other Drivetrain Components
The Deluxe Ultimate RCT rear shock is compatible with a wide range of modern mountain bike drivetrains. It integrates seamlessly with the latest suspension designs, particularly those using an advanced linkage system that requires precise shock alignment. When setting up the rear shock, ensure that your frame and drivetrain components are compatible with the eye-to-eye length and shock mount configuration of the Deluxe Ultimate RCT.
Check your bike’s frame specifications to confirm compatibility with the shock’s mounting system and adjust settings accordingly.
By properly setting up the Deluxe Ultimate RCT rear shock, you can dramatically improve the overall ride quality of your bike, ensuring comfort, control, and efficiency on any terrain.
