Installation of the RockShox SIDluxe Select+ Rear Shock

The SIDluxe Select+ rear shock is designed to be compatible with most modern cross-country frames. Proper installation is crucial for the shock’s performance and longevity. Here are the steps for correctly installing the SIDluxe Select+ on your bike:

1. Prepare the Tools: Ensure that you have the necessary tools for installation:
   • Torque wrench [paid link]
   • Allen wrenches [paid link] (typically 5mm and 6mm)
   • Shock pump
   • Cleaning supplies (rags and degreaser)
   • Threadlocker (optional)
2. Remove the Old Shock (if applicable):
   • Begin by carefully removing any components that might obstruct access to the rear shock.
   • Use the appropriate Allen wrenches [paid link] to unscrew the shock bolts.
   • Make sure to note the orientation of the old shock before removing it to ensure proper installation of the new one.
3. Install the SIDluxe Select+:
   • Align the new shock with the mounting points on your bike frame, ensuring it is correctly positioned.
   • Attach the shock to the frame, tightening the mounting bolts to the manufacturer’s recommended torque settings. Be sure not to overtighten the bolts, as this can cause damage to the frame or shock.
4. Set the Air Pressure:
   • Use the shock pump to adjust the air pressure to your desired setting based on your body weight and riding style. Refer to RockShox’s guidelines for suggested air pressure ranges for optimal performance.
5. Final Checks:
   • Check for proper shock alignment and movement.
   • Test the shock’s function by compressing it and checking for any signs of play or binding.
   • Make sure all bolts are securely tightened and that the shock is positioned correctly.

Adjusting the SIDluxe Select+ for Optimal Performance

The SIDluxe Select+ is equipped with a variety of features that allow riders to fine-tune the suspension to their specific needs. Here are the primary adjustment options:

Rebound Adjustment

The rebound adjustment on the SIDluxe Select+ allows riders to control how quickly the shock returns to its normal position after compression. This is crucial for maintaining control and comfort, especially on rough terrain.

• Clockwise: Slows down the rebound, making the shock return more gradually.
• Counterclockwise: Increases the rebound speed for faster return.

Compression Adjustment

The SIDluxe Select+ features low-speed compression adjustments that allow riders to control the shock’s damping force during initial compression. This adjustment helps to reduce bottoming out on aggressive descents or during large hits.

• Clockwise: Increases compression, making the shock firmer and less prone to bottoming out.
• Counterclockwise: Decreases compression for a softer, more responsive feel on small bumps.

Air Pressure

Adjusting the air pressure is one of the most important steps in getting the SIDluxe Select+ to feel just right. The air pressure setting affects both the shock’s overall performance and the rider’s comfort.

• Higher Air Pressure: Provides a firmer ride with reduced sag and increased responsiveness.
• Lower Air Pressure: Offers more comfort and compliance but may increase the risk of bottoming out on rougher terrain.

Volume Spacers

The SIDluxe Select+ comes with volume spacers that allow for fine-tuning the shock’s progression. These spacers adjust how the shock behaves towards the end of its travel, offering either a more progressive feel or a more linear response.

• Adding Volume Spacers: Increases progression, which reduces the likelihood of bottoming out.
• Removing Volume Spacers: Results in a more linear feel, offering a smoother ride but at the risk of bottoming out on bigger hits.

Maintenance of the SIDluxe Select+ Rear Shock

Regular maintenance is essential to keep the SIDluxe Select+ performing at its best. Here’s how to ensure longevity and optimal performance of the shock.

Cleaning and Inspection

• After Every Ride: Wipe down the shock with a clean rag to remove dirt and debris.
• Check for Leaks: Inspect the shock for any signs of air or oil leaks. Leaks are a clear indication that the shock needs servicing.
• Inspect the Shaft and Body: Check for any scratches or dents on the shock’s shaft or body, as these can affect performance and potentially lead to failure.

Oil Change and Seals

The SIDluxe Select+ requires regular oil changes to ensure smooth operation. The oil inside the shock helps to lubricate the internal parts, reducing wear and tear.

• Service Interval: RockShox recommends servicing the shock every 50-100 hours of riding, or once a year, depending on usage.
• Changing the Oil: To change the oil, carefully remove the shock from the frame, disassemble the shock components, and replace the oil as per RockShox’s instructions.
• Seal Replacement: Inspect and replace seals as necessary to maintain optimal damping performance. Over time, seals can wear out, leading to decreased performance or leaks.

Troubleshooting Common Set-Up Issues

While the SIDluxe Select+ is a high-performance shock, riders may encounter a few issues during setup or riding. Here are common problems and their solutions:

The Shock Feels Too Firm or Too Soft

• Possible Cause: Incorrect air pressure.
• Solution: Adjust the air pressure to match your body weight and riding style. Start with the manufacturer’s recommended range and make small adjustments based on your comfort and performance needs.

The Shock is Bottoming Out Frequently

• Possible Cause: Insufficient air pressure or inadequate compression damping.
• Solution: Increase the air pressure or adjust the compression damping to provide more resistance during hard hits.

Rebound is Too Fast or Too Slow

• Possible Cause: Incorrect rebound setting.
• Solution: Adjust the rebound knob clockwise or counterclockwise until you find the optimal setting for your riding style.

Customization and Optimization for Better Performance

The SIDluxe Select+ offers a wide range of customization options that allow riders to tailor the shock to their specific needs. To get the most out of your shock, consider the following adjustments:

• Fine-Tuning Air Pressure: Experiment with air pressure settings to achieve the ideal balance between comfort and performance. For XC races, a firmer setup may be preferred for better efficiency, while marathon riders may opt for a softer setup for comfort over long distances.
• Adjusting the Compression: Fine-tune the low-speed compression settings to match the terrain. A firmer compression setting can improve performance on smoother trails, while a softer setting may be better suited for rough or technical terrain.
• Volume Spacers: Adding or removing volume spacers can significantly alter the shock’s progression. Riders looking for a more aggressive riding experience on steeper trails may benefit from a more progressive setup.

Compatibility with Other Drivetrain Components

The SIDluxe Select+ rear shock is designed to be compatible with most modern cross-country and marathon bike frames, but it’s important to ensure compatibility with your bike’s other components. The shock’s stroke length and mounting hardware must match your bike’s frame geometry.

• Stroke Length: Verify that the stroke length of the SIDluxe Select+ is compatible with your frame’s rear triangle.
• Mounting Hardware: Ensure that the shock’s eyelet diameter and bushing size match the frame’s shock mount.
• Other Components: The SIDluxe Select+ is designed to work seamlessly with other high-performance components like the SRAM drivetrain. Ensure that your drivetrain components do not interfere with shock travel or performance.

Comparison with Similar Models

When considering the SIDluxe Select+, it’s essential to compare it with similar rear shocks on the market. The SIDluxe Select+ is positioned as a lightweight, high-performance shock suited for cross-country riders, but there are other options to consider:

• Fox Float DPS: A competitor in the same category, the Fox Float DPS offers similar performance but with slightly different tuning and damping features. Some riders prefer the Float DPS for its slightly more plush feel, while others opt for the SIDluxe for its more efficient pedaling response.
• DVO Topaz T3: Another high-end rear shock, the DVO Topaz T3 provides more adjustability, including high-speed compression adjustment. Riders who prioritize fine-tuning every aspect of their suspension may prefer the Topaz T3 over the SIDluxe Select+.

When choosing between these models, it’s important to consider the specific demands of your riding style, the type of terrain you ride, and the overall weight and efficiency of the shock. The SIDluxe Select+ stands out for its ease of use, reliable performance, and ability to cater to a wide range of riders and terrains.
