Installation of the Super Deluxe Ultimate RC2T Rear Shock
Step 1: Prepare Your Frame and Shock
Before installing the Super Deluxe Ultimate RC2T, clean the mounting area on your frame to ensure a secure, debris-free attachment. Use a clean rag to wipe down the shock mount and remove any dirt or old grease from the frame’s eyelet or shock hardware.
Step 2: Install the Shock Mounting Hardware
Carefully install the shock mounting hardware into the eyelets of your frame. Use the appropriate bolt and washer combination based on your bike model. Ensure the shock is oriented correctly and that the mounting hardware is properly seated in the shock’s eyelet bushings.
Step 3: Attach the Shock to the Frame
Position the shock so that the eyelets align with the mounting hardware on the frame. Insert the bolts and tighten them with the 8mm Allen wrench. Be sure to torque the bolts to the recommended settings specified in the Super Deluxe Ultimate RC2T manual, typically between 8–10 Nm, depending on the specific frame.
Step 4: Set the Air Pressure
Once the shock is mounted, use a shock pump to set the correct air pressure based on your rider weight and riding style. Refer to the RockShox guidelines for recommended pressures, or use the suggested pressures found on the shock’s label. Generally, a rider’s weight plus a few psi will provide the best starting point for tuning.
Step 5: Final Check
Double-check all bolts to ensure they are secure. Check for smooth operation by cycling the suspension through its range of motion to confirm the shock moves freely.
Adjustments for Optimal Performance
Compression Damping
The Super Deluxe Ultimate RC2T offers both low-speed and high-speed compression adjustments. These allow you to fine-tune the shock’s response based on terrain conditions and riding preferences.
- Low-speed compression: Adjust this knob to control the shock’s response to small bumps or low-speed movements. For more plush performance, set it to a lower setting. For a firmer, more responsive feel, increase the compression.
- High-speed compression: This adjustment controls how the shock handles larger impacts, such as drops or big hits. Set the high-speed compression based on the type of terrain you ride. A firmer setting is ideal for fast descents, while a softer setting is better for trail riding or technical climbs.
Rebound Damping
Rebound damping is critical to control the speed at which the shock returns after compression. If your shock returns too quickly, it could cause a “bucking” sensation; too slowly, and you may feel “bogged down.”
- To adjust, turn the Rebound Knob clockwise for slower rebound and counterclockwise for faster rebound. A good starting point is to set it to a moderate position and adjust based on your ride feel.
Lockout
The RC2T features a lockout function that allows you to stiffen the shock for efficient pedaling, especially on smooth terrain. This is especially useful during climbs or on flat sections of the trail. Make sure to disengage the lockout when descending or tackling technical terrain to allow the shock to absorb impacts.
Maintenance and Servicing
Regular Cleaning
Maintaining a clean shock is essential for long-lasting performance. After every ride, especially after muddy or wet conditions, wipe down the shock with a clean, dry rag. Use a soft brush to clean any debris or dirt from the shock’s body and air spring area. Avoid using harsh chemicals that could damage the shock.
Air Spring Maintenance
Over time, air can escape from the shock’s air spring. To ensure the shock operates correctly, check the air pressure regularly (before each ride). If the air pressure drops or the shock feels less responsive, add air using a shock pump until you reach the desired pressure.
Suspension Fluid
For optimal performance, the Super Deluxe Ultimate RC2T requires periodic suspension fluid changes. Typically, this should be done every 50-100 hours of riding, depending on the conditions and frequency of use. Changing the suspension fluid ensures consistent damping performance.
To replace the fluid:
- Remove the shock from the frame.
- Use the RockShox service kit and syringe to remove the old suspension fluid.
- Replace the fluid with the recommended RockShox fluid, ensuring the correct viscosity for your riding conditions.
- Reassemble the shock and ensure it operates smoothly by cycling it several times before reinstalling.
Air Can Service
Periodically, you should perform a thorough inspection of the air can. Remove the shock’s air can and inspect the internal seals for wear or damage. Lubricate the seals with fresh suspension fluid before reassembling the shock. This step helps to maintain the performance and longevity of the shock’s air spring.
Troubleshooting Common Set-Up Issues
Shock Not Holding Air
If your shock is losing air pressure rapidly, it could be a sign of a leak in the air spring or the valve. Inspect the air valve for damage or debris. If the valve is functioning correctly, check the shock’s seals. A damaged seal may require a rebuild.
No Rebound Dampening
If you notice a lack of rebound damping, the shock might have insufficient fluid or a faulty rebound damper. In this case, performing a full shock service is recommended to inspect the damper assembly and refill the necessary fluid.
Compression Problems
If the shock feels excessively stiff or too soft during compression, there could be an issue with the internal dampers or the fluid levels. Adjust the low-speed and high-speed compression knobs to ensure they are functioning correctly. If the issue persists, a suspension service may be necessary to inspect internal components.
Customization and Optimization
Fine-Tuning for Riding Style
The Super Deluxe Ultimate RC2T can be adjusted to suit various riding styles and terrain types. Here are some suggestions:
- For trail riding or XC racing, set the compression to a firmer setting and dial in a faster rebound for efficiency.
- For enduro or downhill, a softer compression setting with slower rebound can provide maximum control over rough terrain.
- Technical riders who require a mix of both might opt for a balanced setup, with moderate compression and rebound adjustments.
Weight Considerations
The Super Deluxe Ultimate RC2T offers a great range of air pressure adjustment, so it can be optimized for riders of various weights. Remember to account for rider weight and any extra gear or bike modifications when setting air pressure. Adjusting the air spring in small increments and testing the shock on the trail will help you find the optimal setting for comfort and performance.
Comparison with Similar Models
Super Deluxe vs. Monarch Plus
While the Super Deluxe Ultimate RC2T offers superior adjustability with both low-speed and high-speed compression settings, the Monarch Plus is more straightforward, offering basic rebound and compression adjustments. The Super Deluxe is designed for riders who need more customization and refined performance, particularly for aggressive riders or those tackling challenging terrain.
The Super Deluxe is also lighter and typically offers better small bump sensitivity due to its more advanced damper technology. However, if you’re a recreational rider or prefer a simpler set-up, the Monarch Plus might be the more suitable option.
Super Deluxe vs. Fox Float X2
In comparison to the Fox Float X2, the Super Deluxe Ultimate RC2T offers similar high-end performance, but it has a slightly more user-friendly tuning range. The Fox Float X2 excels in extreme performance but may require more frequent servicing, while the Super Deluxe offers a more balanced approach, providing excellent performance with less maintenance.
Compatibility with Other Drivetrain Components
The Super Deluxe Ultimate RC2T rear shock is compatible with most modern mountain bike frames that use a standard eyelet size. However, compatibility with other drivetrain components is also important when considering the overall performance of your bike. Ensure your shock is compatible with your frame’s suspension design (e.g., Horst Link, VPP) and that the shock length and stroke are suitable for your bike’s geometry.
