Known for its durability, fine-tuned adjustability, and advanced features, the Deluxe Ultimate RCT is a preferred option for both amateur and professional cyclists seeking precision control and superior ride quality. In this guide, we’ll cover the key reasons why this rear shock is a top choice, providing insights on installation, maintenance, troubleshooting, and customization.

Key Features of the Deluxe Ultimate RCT Rear Shock

The Deluxe Ultimate RCT rear shock integrates several features that make it suitable for aggressive trail riders, cross-country racers, and enduro enthusiasts. Here are the primary reasons why riders choose this shock:

1. Premium DebonAir Spring System

One of the standout features of the Deluxe Ultimate RCT is the DebonAir spring system. This air spring design enhances rider comfort by offering a more consistent and smoother feel across all types of terrain. The DebonAir system delivers a greater volume of air, which helps in maintaining sensitivity and responsiveness throughout the travel. Riders can enjoy a more plush ride, especially in rough terrain, without compromising performance.

2. RCT3 Damper Technology

The RCT3 damper system in the Deluxe Ultimate RCT offers three distinct compression settings: Open, Pedal, and Lock. This adjustability allows riders to fine-tune the shock to their specific riding style and terrain. The Open mode is perfect for descending or technical riding, providing maximum performance and control. The Pedal mode minimizes pedal bob for efficient climbing, and the Lock mode offers minimal movement, ideal for flat sections or during extended climbs.

3. High-Quality Materials for Durability

RockShox has designed the Deluxe Ultimate RCT with durability in mind. The shock features high-quality materials such as aluminum for lightweight strength and steel components for increased resilience. This makes the shock suitable for rigorous riding in demanding environments, from muddy trails to rocky descents, while maintaining long-term reliability.

4. Precision External Adjustments

The Deluxe Ultimate RCT provides a range of external adjustments, making it easy to fine-tune performance. These include adjustments for rebound, high-speed compression, and low-speed compression. These settings allow the rider to adjust the shock for different riding styles, body weight, and terrain conditions, ensuring optimal performance for every ride.

5. Fast and Simple Setup

Installing and setting up the Deluxe Ultimate RCT rear shock is quick and straightforward. It’s designed to be compatible with a wide range of bikes, making it a versatile choice for various setups. Whether you’re a beginner or an experienced rider, the shock’s user-friendly interface and clear adjustment features make it easy to configure the settings to your preference.

  1. Prepare the bike: Ensure the bike is stable by placing it on a bike stand [paid link]. Make sure the rear triangle is clean and free from debris.
  2. Remove the old shock: Use a 5mm Allen wrench [paid link] to remove the mounting bolts securing the previous shock. Keep the bolts in a safe place for reinstallation if you are replacing an existing shock.
  3. Install the new shock: Carefully place the Deluxe Ultimate RCT in the mounting eyelets. Ensure it aligns with the shock mounts properly.
  4. Tighten the bolts: Using the torque wrench [paid link], tighten the mounting bolts to the manufacturer’s recommended torque settings. Be sure not to overtighten, as this can damage the shock or frame.
  5. Set the sag: Use a shock pump to adjust the air pressure to the recommended level based on your weight. Setting the sag correctly is essential for the optimal function of the shock.
  6. Test the shock: Once installed, perform a quick test to check for smooth operation. Adjust the air pressure and damping settings based on your riding preferences.

Maintenance and Care of the Deluxe Ultimate RCT Rear Shock

To ensure the Deluxe Ultimate RCT rear shock continues to perform optimally, regular maintenance is essential. Here are some essential maintenance tasks to consider:

1. Cleaning the Shock

After every ride, especially after muddy or wet conditions, wipe down the shock with a clean, damp cloth to remove dirt and debris. Pay special attention to the shaft, the seals, and the mounting hardware to prevent wear and damage. Avoid using harsh chemicals that could degrade the seals or lubricants.

2. Inspecting the Shock for Wear

Regularly inspect the shock for signs of wear such as leaking oil, excessive play in the eyelets, or damage to the damper. If you notice any unusual sounds or changes in performance, it’s a good idea to consult with a bike mechanic for a thorough inspection.

3. Lubricating the Shock Seals

To prevent friction and ensure smooth operation, it’s important to regularly lubricate the shock’s seals. Apply a small amount of shock oil or lubricant to the seals, but avoid excessive amounts that could attract dirt.

4. Servicing the Shock

Over time, internal maintenance such as replacing seals, oils, and air-spring services may be required. Depending on your riding conditions, RockShox recommends servicing the shock every 50-100 hours of riding or at least once per year. It’s recommended to have the shock serviced by a professional to maintain the highest level of performance.

Troubleshooting Common Issues with the Deluxe Ultimate RCT

While the Deluxe Ultimate RCT is a highly reliable rear shock, issues can arise that affect performance. Below are some common problems and solutions:

1. Shock Not Rebounding Properly

  • Issue: If the shock doesn’t rebound properly or is sluggish, the rebound damping may be set too high.
  • Solution: Adjust the rebound setting by turning the rebound knob counterclockwise to increase the rebound speed.

2. Excessive Sag

  • Issue: Too much sag can cause the bike to feel sluggish or unresponsive.
  • Solution: Adjust the air pressure using the shock pump to achieve the correct sag based on your body weight.

3. No Compression Adjustments

  • Issue: If the shock feels overly soft or stiff regardless of adjustments, the compression damper might need to be checked.
  • Solution: Check that the high and low-speed compression adjustments are set correctly. If adjustments don’t affect the shock, it may need servicing.

Customizing the Deluxe Ultimate RCT for Better Performance

To further optimize the Deluxe Ultimate RCT for your specific riding style, consider the following customization options:

1. Adjusting the Compression and Rebound Settings

Experiment with different high-speed and low-speed compression settings to find the optimal balance between comfort and performance. Adjusting the rebound can help you fine-tune the shock to feel more responsive or more controlled depending on your preference.

2. Changing Air Pressure

Adjusting the air pressure in the shock based on your weight and riding style can significantly affect the shock’s performance. A lower pressure will provide a more supple ride, while higher pressure will give you more support and less sag.

3. Upgrading the Mounting Hardware

Consider upgrading the mounting hardware to titanium or other high-strength materials for reduced weight and increased durability. This can be particularly beneficial for competitive riders looking to shave off grams while maintaining strength.

Comparison with Similar Models

While the Deluxe Ultimate RCT is a high-performance rear shock, it’s useful to compare it with similar models in RockShox’s lineup. The Super Deluxe and Monarch series are also excellent choices but offer slightly different performance features and tuning options. For example, the Super Deluxe is geared more towards aggressive riding and features a more advanced damper, while the Monarch is designed for lighter riders and cross-country use.

Compatibility with Other Drivetrain Components

The Deluxe Ultimate RCT is compatible with a wide range of drivetrain components, including those from Shimano and SRAM. When choosing a rear shock, it’s important to ensure that the frame design, shock length, and mounting hardware are compatible with your bike’s drivetrain for seamless integration. It’s always a good idea to consult with a bike shop to confirm compatibility.

The Deluxe Ultimate RCT rear shock from RockShox offers a remarkable combination of performance, adjustability, and durability. Whether you’re tackling technical descents or enduring long climbs, this rear shock ensures a smooth and controlled ride across a variety of terrains. With proper installation, maintenance, and customization, you can optimize its performance for any ride, making it an excellent choice for discerning mountain bikers.
