The RockShox Super Deluxe Coil Ultimate rear shock is a premium component designed for performance and durability on demanding trails. Known for its high-end coil suspension and robust construction, this shock offers superb performance but requires proper care and maintenance to ensure optimal performance. In this guide, we’ll walk you through the installation, adjustment, maintenance, and troubleshooting steps to keep your Super Deluxe Coil Ultimate rear shock working at its best.
Tools Required
- 8mm Allen wrench [paid link]
- 10mm socket or wrench
- Torque wrench [paid link] (3-30Nm range)
- Shock pump (compatible with RockShox models)
- Clean rags or paper towels
- RockShox air shaft removal tool (if needed)
- Suspension oil (RockShox specific)
- Teflon tape (for threads)
- Replacement seals and O-rings (if required)
Installing the Super Deluxe Coil Ultimate Rear Shock
Proper installation is key to ensuring your Super Deluxe Coil Ultimate rear shock functions properly. Follow these steps for an accurate and secure installation:
- Remove the old shock: Use the 8mm Allen wrench [paid link] to detach the bolts securing the existing shock to the frame. Ensure the bike is secure and stable during the process.
- Prepare the new shock: Ensure the shock is compatible with your bike’s frame size and that it has the correct spring rate. If needed, replace the existing spring with one suited to your riding style and weight.
- Attach the shock to the frame: Position the shock in the rear triangle of your bike. Tighten the mounting bolts using the 10mm socket or wrench, securing the shock firmly to the frame.
- Set the correct sag: Using a shock pump, adjust the air pressure to achieve the correct sag for your weight and riding style. Typically, the sag should be between 25-30% of the shock’s total travel.
- Torque the bolts: Use a torque wrench [paid link] to tighten the mounting bolts to the recommended torque specifications, usually between 150-180Nm for the mounting hardware.
Ensure everything is tightened to specification to avoid issues during your ride.
Adjusting the Super Deluxe Coil Ultimate Rear Shock
The RockShox Super Deluxe Coil Ultimate offers several adjustments to optimize performance. Here are the key adjustments:
Rebound Adjustment
Rebound adjustment controls how quickly the shock returns after compression. The Super Deluxe Coil Ultimate has a red rebound knob on the bottom of the shock.
- Turn the knob clockwise to slow down rebound.
- Turn the knob counterclockwise to speed up rebound.
Start with the rebound set to mid-position and adjust based on your riding style and the terrain. Slower rebound may be beneficial on rough, fast trails, while quicker rebound helps on smoother surfaces.
Compression Adjustment
The compression adjustment determines how much the shock resists compression. The Super Deluxe Coil Ultimate features a high-speed and low-speed compression adjustment on the external damper.
- Low-speed compression: This affects the shock’s behavior on small, low-speed bumps. Turn the dial clockwise to increase compression and make the shock stiffer.
- High-speed compression: This affects the shock’s resistance to large impacts. Adjust this to control how the shock reacts to big hits or drops.
Spring Preload Adjustment
The coil spring’s preload can be adjusted to fine-tune the shock’s stiffness. The preload controls the initial sag and helps you match the shock to your weight. To adjust:
- Turn the preload collar to increase or decrease the preload on the spring.
- Make small adjustments to get the right amount of sag (typically 25-30%).
Maintaining the Super Deluxe Coil Ultimate Rear Shock
Routine maintenance ensures the longevity and performance of your Super Deluxe Coil Ultimate. Here’s how to keep it in top shape:
Regular Cleaning
After each ride, wipe down the shock with a clean rag or paper towel. Remove any dirt, mud, or debris from the shock body and seals. This will prevent contaminants from entering the suspension system and causing wear.
O-Ring Maintenance
Check the O-rings on the shock for any signs of wear or damage. If they are cracked or worn, replace them with new ones to avoid leakage or compromised performance.
Suspension Oil Service
Over time, the suspension oil inside the shock can degrade. RockShox recommends servicing the shock every 50-100 hours of riding, depending on the conditions.
- Drain the oil: Remove the air can and damper body, draining the oil from the shock.
- Clean the components: Use a rag to wipe down all internal parts, ensuring no debris remains inside.
- Replace the oil: Refill the shock with fresh suspension oil, following RockShox’s recommended oil type and volume.
Seals and Bushings Replacement
Inspect the seals and bushings periodically. If you notice any leaking fluid or excessive play in the shock, it’s time to replace the seals and bushings. These can be purchased as a service kit from RockShox.
Troubleshooting Common Set-Up Issues
If your Super Deluxe Coil Ultimate rear shock isn’t performing as expected, there are several common issues that can be easily diagnosed and fixed.
Issue: Lack of Rebound Control
If you experience a lack of rebound control, it may be due to incorrect adjustment or a low oil level.
- Solution: Adjust the rebound knob to ensure it’s set correctly. If the shock still rebounds too quickly or too slowly, check the oil level inside the damper and top it off if needed.
Issue: Sag Too High or Too Low
If the sag is not within the recommended range, the shock may not be set up properly for your weight or riding style.
- Solution: Adjust the preload collar to achieve the correct sag. If the preload doesn’t fix the issue, consider changing the spring rate to better match your weight and riding style.
Issue: Noisy Shock
A noisy shock can be caused by dirt in the bushings or worn-out seals.
- Solution: Clean the shock thoroughly and inspect the seals. Replace any worn parts to reduce noise and ensure smooth operation.
Customization and Optimization for Better Performance
To get the most out of your RockShox Super Deluxe Coil Ultimate rear shock, consider these tips for optimization:
- Coil Spring Upgrade: If you’re riding aggressive trails or need more support, consider upgrading to a higher-rated coil spring to handle bigger hits.
- Suspension Tuning: Fine-tune the low-speed and high-speed compression settings to match your preferred riding style and terrain.
- Air Can Volume Adjustments: Some riders prefer to increase or decrease the air can volume for a more progressive or linear shock feel. If you’re looking for a more bottomless feel, consider using the larger air can option.
Compatibility with Other Drivetrain Components
The Super Deluxe Coil Ultimate rear shock is compatible with a wide range of mountain bikes. However, it’s important to check compatibility with your bike’s frame, specifically the shock mounting hardware, as different manufacturers may have varying requirements for shock eyelet sizes and hardware.
Additionally, pairing the Super Deluxe Coil Ultimate with a high-end drivetrain and braking system will optimize the performance of your bike, ensuring a smooth and controlled ride.
