Tools Required

  • 8mm Allen key
  • 5mm Allen key
  • Shock pump
  • Torque wrench [paid link]
  • T25 Torx wrench [paid link]
  • Suspension oil (if needed)
  • Cleaning supplies (rags, mild soap, water)
  • Loctite (blue threadlocker)
  • A helper (optional but recommended for installation)

Installation of Super Deluxe Ultimate RCT

Installing the Super Deluxe Ultimate RCT [paid link] Rear Shock on your bike requires precision and attention to detail to ensure optimal performance. Follow these steps to install the shock correctly.

Step 1: Remove the Old Rear Shock

Before installing the new shock, remove the old rear shock from your bike. Use the 8mm Allen key to loosen the bolts securing the shock to the frame. Be sure to keep the hardware in case you need it for the new shock.

Step 2: Prepare the Super Deluxe Ultimate RCT

Once the old shock is removed, prepare the Super Deluxe Ultimate RCT. Check that the shock is properly greased (if applicable) and inspect the mounting hardware to ensure it is in good condition. If needed, apply Loctite to the threads to prevent them from loosening over time.

Step 3: Install the New Shock

Position the shock into the frame, ensuring the eyelets line up with the mounting hardware. Using the 8mm Allen key, tighten the top and bottom bolts. Ensure that the bolts are tightened to the manufacturer’s torque specifications, usually found in the user manual or shock documentation. It’s important not to overtighten the bolts to avoid damaging the frame or shock.

Step 4: Set Up Initial Air Pressure

Once the shock is secured, attach a shock pump to the air valve and add air according to your rider weight and riding style. Typically, start with the recommended air pressure listed in the user manual, and adjust based on personal preference. Ensure that the pressure is correct before proceeding to the next step.

Step 5: Check for Proper Functioning

After installation, check the suspension’s operation by compressing the shock and ensuring smooth movement. The Super Deluxe Ultimate RCT should have no signs of binding or excessive movement. If necessary, make small adjustments to the air pressure and rebound settings to get the shock feeling right.

Adjustment of Super Deluxe Ultimate RCT

The Super Deluxe Ultimate RCT comes with several features for fine-tuning the suspension to match your riding style and conditions. These features include air pressure adjustment, rebound damping, and the external compression adjustment. Below is a guide to adjust each of these components.

Air Pressure Adjustment

Adjusting air pressure is essential to achieving a plush and responsive ride. The air pressure affects the shock’s overall sag, which determines how much travel is used under rider weight. To set air pressure:

  1. Use the shock pump to adjust the air in the shock.
  2. To calculate the correct pressure, refer to the rider weight chart in the manual. Start at the recommended level and adjust based on how the bike feels.
  3. For trail riding, aim for a sag of around 25-30% of the shock’s total travel. This will ensure that the shock performs optimally without feeling too stiff or too soft.

Rebound Damping Adjustment

Rebound damping controls how quickly the shock returns to its original position after compressing. If the rebound is too fast, the shock may “pack up,” meaning it will not recover quickly enough between impacts. If it’s too slow, it may feel sluggish and reduce performance. To adjust:

  1. Turn the rebound knob (located at the bottom of the shock) clockwise to slow the rebound and counterclockwise to speed it up.
  2. Make adjustments in small increments and test ride the bike after each change.

Compression Adjustment

The compression settings control how the shock behaves under load, such as when hitting a big bump or landing from a jump. The Super Deluxe Ultimate RCT features a high-speed compression adjustment dial, allowing for fine-tuning based on trail conditions. To adjust:

  1. Turn the compression knob clockwise to increase compression, making the shock stiffer and reducing the amount of travel.
  2. Turn it counterclockwise to decrease compression, allowing for more travel and a more supple ride on rough terrain.

Maintenance of Super Deluxe Ultimate RCT

Maintaining your Super Deluxe Ultimate RCT shock ensures its longevity and keeps it performing at its peak [paid link]. Regular maintenance should include cleaning, oil changes, and shock servicing.

Cleaning and Inspection

After each ride, wipe down the shock with a clean rag to remove dirt and debris. This prevents buildup that could affect the shock’s performance. Pay special attention to the air valve and seals, ensuring they are free of dirt and moisture. Inspect the shock for signs of damage or wear, such as oil leaks or bent parts.

Suspension Oil Maintenance

At regular intervals (typically every 50-100 hours of riding), it’s recommended to change the suspension oil. This prevents internal wear and ensures smooth shock performance. To perform an oil change:

  1. Remove the shock from the bike.
  2. Disassemble the shock according to the manufacturer’s instructions.
  3. Drain old oil, clean the internal parts, and replace with fresh suspension oil.

Seal Maintenance

Check the shock seals for wear every few months. If the seals are cracked or leaking oil, replace them with new ones. This is a relatively simple process that will help extend the life of the shock and maintain optimal performance.

Troubleshooting Common Set-Up Issues

Despite its high-performance design, users may encounter a few common set-up issues with the Super Deluxe Ultimate RCT. Here are solutions to help address them.

Issue 1: Shock Bottoming Out

If the shock bottoming out too easily, it may indicate that the air pressure is too low or the rebound damping is set too fast. Start by increasing the air pressure slightly to achieve the proper sag. Then, adjust the rebound to slow down the shock’s return rate.

Issue 2: Unresponsive or Stiff Shock

If the shock feels stiff or unresponsive, ensure that the compression and rebound settings are properly adjusted. Additionally, check that the shock is adequately lubricated and free of dirt. If the shock still feels unresponsive, it may need to be serviced by a professional.

Issue 3: Noises or Leaks

If you notice any unusual noises or fluid leaks, inspect the shock seals and air valve carefully. Leaks usually indicate a damaged seal or air valve, which will need to be replaced to avoid further issues.

Customization and Optimization

The Super Deluxe Ultimate RCT is a highly tunable shock, and riders can further optimize it for specific riding conditions. Adjusting the settings based on personal preferences can help tailor the shock’s performance to suit different trail types and riding styles.

Adjusting for Enduro Riding

For enduro racing, riders often prefer a firmer shock setup with a higher air pressure and firmer compression damping. This helps prevent bottoming out on big hits while still allowing for smooth performance on rough descents.

Adjusting for Cross-Country

Cross-country riders may prefer a more supple ride, with lower air pressure and softer compression settings. This setup provides better traction and comfort over uneven terrain, making pedaling more efficient.

Comparison to Similar Models

When comparing the Super Deluxe Ultimate RCT to other rear shocks in the market, such as the Fox Float X2 or the RockShox Monarch Plus, the Super Deluxe stands out for its high level of adjustability and lightweight design. While the Monarch Plus offers excellent performance for cross-country riding, the Super Deluxe Ultimate RCT shines with its versatility, offering superior performance across a wider range of riding conditions, from aggressive downhill to technical trail riding.

Compatibility with Other Drivetrain Components

The Super Deluxe Ultimate RCT is designed to be compatible with most modern mountain bike frames, though it is important to ensure that the shock’s eyelet dimensions and travel are suitable for your bike. It can be paired with a variety of drivetrains, including SRAM and Shimano systems, without causing interference with the suspension’s function.

The shock’s air spring design and adjustable damping system allow it to complement most suspension forks, ensuring a balanced and harmonious ride across both ends of the bike.
