The RockShox Super Deluxe Ultimate RC2T rear shock is a top-tier suspension component used in high-performance mountain bikes. Known for its durability and precise adjustment features, it offers a smooth ride on a variety of terrains. However, like any high-performance piece of equipment, it can encounter issues over time. This guide will walk you through common problems you might face with the Super Deluxe Ultimate RC2T and how to troubleshoot them effectively.
Introduction to the Super Deluxe Ultimate RC2T Rear Shock
The Super Deluxe Ultimate RC2T rear shock from RockShox is engineered for aggressive riders looking for the ultimate suspension performance. It features RockShox’s advanced damping technology, including external adjustments for rebound, compression, and the dual position lever. These adjustments help to fine-tune the ride and ensure that the shock performs optimally under different conditions. Despite its high-quality build, problems can occasionally arise, which may affect the shock’s performance. Troubleshooting and maintenance can restore functionality and extend the shock’s lifespan.
Common Issues with the Super Deluxe Ultimate RC2T Rear Shock
1. Lack of Rebound Control
One of the most common issues riders experience with the Super Deluxe Ultimate RC2T is inadequate rebound control. This is typically due to improper rebound damping settings, resulting in either too slow or too fast rebound after compression.
Possible Causes:
- Incorrect rebound settings: Too fast or too slow.
- Damping fluid contamination or air in the system.
- Incorrect air pressure.
Troubleshooting:
- Check rebound setting: Adjust the rebound knob in small increments. Turn it clockwise to slow the rebound or counterclockwise to speed it up.
- Flush and service the shock: If the rebound setting does not adjust correctly, it may be time to service the shock. Clean the shock and flush the damping system to remove any contamination.
- Check air pressure: Ensure the shock is properly inflated. Low or excessive air pressure can affect rebound performance.
2. Bottom-Out Issues
If you find that your rear shock bottoms out too easily, it may lead to a harsh ride, especially during aggressive descents or big impacts. This issue is often due to insufficient compression damping or incorrect air pressure.
Possible Causes:
- Low compression damping.
- Incorrect air pressure.
- Internal oil leakage.
Troubleshooting:
- Adjust compression settings: Turn the compression knob to increase damping for better control. Adjust it gradually while testing the bike to find the right balance.
- Inspect air pressure: Ensure the shock’s air pressure is correctly set according to the manufacturer’s recommendations.
- Check for internal damage: If the issue persists, inspect for oil leakage, which may require a full rebuild or service from a professional.
3. Sag and Air Pressure Problems
Proper air pressure is crucial to the Super Deluxe Ultimate RC2T’s performance. If the air pressure is too low, the shock will sag excessively, while too much air pressure will make the ride harsh.
Possible Causes:
- Incorrect air pressure setting for rider weight.
- Leaks in the air chamber.
- Shock seal damage.
Troubleshooting:
- Check air pressure: Use a shock pump to set the recommended air pressure based on your rider weight. Recheck air pressure regularly.
- Inspect for leaks: If the shock loses air pressure quickly, inspect the air valve and seals for leaks. Replacing worn seals might be necessary.
- Test the sag: Ensure the sag is within the recommended range for optimal performance. If the sag is too much or too little, adjust the air pressure accordingly.
4. Suspension Lockout Not Engaging
The Super Deluxe Ultimate RC2T is equipped with a dual position lever that allows you to lock out the shock for climbing. If this lever fails to engage or disengage properly, it can be frustrating during your ride.
Possible Causes:
- Dirt or debris in the lever mechanism.
- Internal failure of the lockout system.
- Incorrect installation or adjustment of the lever.
Troubleshooting:
- Clean the lever: Remove dirt or debris from the lockout lever and the mechanism. Regular cleaning can prevent blockage that may affect functionality.
- Check the cable: Ensure the cable that connects the lever to the shock is properly adjusted and has no slack.
- Inspect internal components: If the lever doesn’t engage or disengage, there may be an issue inside the shock itself. This may require servicing to inspect the internal components for wear or failure.
5. Excessive Noise or Creaking
Noise coming from the shock, especially creaking, can be indicative of internal wear or improper installation.
Possible Causes:
- Loose mounting bolts.
- Dry or dirty shock parts.
- Worn-out seals.
Troubleshooting:
- Tighten mounting bolts: Check the bolts holding the shock in place. Loose bolts can cause noise and affect shock performance.
- Lubricate the shock parts: Regularly lubricate the shock’s eyelet bushings and any moving parts. Ensure the shock is properly cleaned and free of dirt.
- Replace seals: If the shock has developed creaking, inspect the seals for wear and replace them if necessary.
Maintenance Tips for the Super Deluxe Ultimate RC2T
To keep your Super Deluxe Ultimate RC2T rear shock in top condition, regular maintenance is essential. Here are some key tips to maintain optimal performance:
1. Regular Servicing
- RockShox recommends servicing your shock annually or after 200 hours of riding. During a service, the shock will be disassembled, cleaned, and any worn components will be replaced.
2. Check Air Pressure Frequently
- Regularly check the air pressure in the shock before each ride to ensure it is within the recommended range for your weight. This will prevent sag and improve performance.
3. Inspect for Leaks
- Regularly inspect the shock for any signs of oil leakage. If you notice any leaks around the shock body or air valve, have the shock serviced immediately to prevent further damage.
Conclusion
The RockShox Super Deluxe Ultimate RC2T rear shock is a high-performance suspension component that can provide a smooth, controlled ride when properly maintained and adjusted. Troubleshooting common issues like rebound control, bottom-out problems, and sag issues can help you restore your shock’s performance and extend its lifespan. Regular servicing, proper air pressure, and careful inspection will ensure that the shock continues to perform at its best, providing a reliable and comfortable ride.
