Setting up the sag on your RockShox Deluxe Select+ rear shock is a critical part of optimizing your bike’s suspension system for comfort and performance. Sag is the amount the shock compresses under your weight, and it plays a vital role in maintaining proper geometry and handling of the bike. This guide will take you step-by-step through the process of setting up sag on the Deluxe Select+ rear shock, troubleshooting common issues, and ensuring optimal performance.
Tools Required
- Shock pump
- Ruler or tape measure
- Bathroom scale (optional)
- Helper (optional, for easier setup)
- Suspension grease (for maintenance)
- Torx driver (if necessary for hardware adjustments)
Understanding Sag and Its Importance
Sag is essential for achieving a balanced ride. If your shock sags too much, your bike may feel sluggish, and you may lose responsiveness. If it sags too little, it can lead to an overly harsh ride and potential loss of traction. The correct sag will help your suspension absorb shocks efficiently while keeping your bike responsive and stable.
The Deluxe Select+ rear shock is designed to provide a smooth ride while being adjustable for different types of terrain and riding styles. By setting up the sag properly, you’ll allow the shock to function optimally.
Setting Up the Sag on Your Deluxe Select+ Rear Shock
Step 1: Prepare Your Bike
Start by ensuring your bike is on a stable surface. It’s best to perform this setup while your bike is upright, ideally on a stand, but it can also be done on the ground. If you’re doing this alone, it might be easier with a helper to assist with measurements and balance.
Step 2: Adjust the Shock Pressure
Before adjusting the sag, you’ll need to adjust the air pressure in the shock. The Deluxe Select+ uses an air spring system, so you’ll need to pump the shock to the correct pressure according to your weight.
- Use a shock pump to add air pressure to the shock.
- Refer to the manufacturer’s recommended pressure chart for your weight and riding style. Generally, a range of 180-220 psi is common for most riders, but this can vary.
- Check the pressure on the shock pump gauge to ensure it is accurate.
Step 3: Measure the Sag
To measure the sag, you’ll need a ruler or tape measure. Follow these steps:
- Measure the uncompressed shock length: This is the length of the shock when it is not under any load. You can find the shock’s uncompressed length in the product manual or measure it directly.
- Sit on the bike: While wearing your full riding gear, sit on the bike in your normal riding position. You can either use a bathroom scale to ensure your full weight is applied or have a friend assist you by holding the bike upright.
- Mark the shock’s compressed length: After sitting on the bike, the shock will compress slightly. Use your ruler or tape measure to mark the point on the shock’s stanchion where it has compressed under your weight.
- Calculate the sag: The sag is calculated by subtracting the compressed length from the uncompressed length and dividing it by the uncompressed length. Multiply this by 100 to get the percentage of sag. The ideal sag for the Deluxe Select+ is typically between 25% and 30% of the shock’s total travel.
Step 4: Adjusting the Air Pressure
If the sag is too little (under 25%), you’ll need to reduce the air pressure. This will allow the shock to compress more under your weight. Conversely, if the sag is too much (over 30%), you will need to increase the air pressure to prevent excessive compression.
- To adjust the pressure, simply use the shock pump to add or release air.
- Check the sag again after adjustments to ensure it falls within the desired range.
Step 5: Fine-Tuning the Setup
After you’ve reached the desired sag, you can fine-tune the shock for your riding style and terrain. This involves adjusting the rebound and compression settings, which will further optimize the shock’s performance.
- Rebound: The rebound adjustment controls how quickly the shock returns after compression. For faster, more aggressive riding, set the rebound faster. For smoother, more controlled rides, set it slower.
- Compression: The compression setting adjusts how much the shock resists compression. A softer compression is ideal for rough terrain, while a firmer setting can be beneficial for smoother trails or to prevent bottoming out on big hits.
Troubleshooting Common Sag Setup Issues
Sag Too Soft or Too Harsh
- Sag too soft: If your sag exceeds 30%, the shock may feel too soft, leading to poor performance. Increase the air pressure to stiffen the spring and reduce the sag.
- Sag too harsh: If your sag is below 25%, the ride might feel too stiff, leading to discomfort and less effective absorption of bumps. Reduce the air pressure to allow the shock to compress more easily.
Air Leaks
If the sag won’t hold steady after adjustments, inspect the shock and air valve for leaks. Check the valve for any dirt or debris that may prevent it from sealing properly. If the problem persists, contact RockShox for assistance or servicing.
Bottoming Out
If the shock frequently bottoms out during aggressive riding, you may need to increase the air pressure to prevent full compression. Alternatively, adjusting the compression damping could help prevent the shock from being too soft under heavy loads.
Customization and Optimization for Better Performance
Adjusting for Different Terrain
The Deluxe Select+ is versatile and can be adjusted to perform optimally on various types of terrain. For rough, rocky trails, consider a softer compression setting to absorb bumps more effectively. For smoother roads or cross-country riding, a firmer compression setting will provide a more efficient pedal stroke and prevent unwanted shock movement.
Changing the Air Volume
You can also adjust the air volume in the Deluxe Select+ for more customized performance. By adding or removing volume spacers, you can change how the shock behaves under different types of loads, enhancing either plushness or support as needed.
Comparing Deluxe Select+ with Other Rear Shocks
When compared to other rear shocks, the Deluxe Select+ stands out for its smooth performance, affordability, and versatility. It provides excellent value for riders looking for a reliable shock without breaking the bank. Other models in the RockShox line, such as the Super Deluxe or Monarch, offer similar features but may include more advanced adjustments for experienced riders or those with specialized needs. The Deluxe Select+ strikes a good balance for riders who want solid performance without complexity.
Compatibility with Other Drivetrain Components
The Deluxe Select+ rear shock is designed to work with a wide range of bikes, but it’s essential to ensure compatibility with your bike’s frame, drivetrain, and suspension system. Make sure the shock’s mounting hardware matches your bike’s specifications, and check for compatibility with other components like the front fork, brake setup, and wheel size. For riders upgrading their suspension system, consider the overall geometry and suspension balance of your bike to ensure optimal performance.
By following these steps and tips for setup, maintenance, and customization, you’ll maximize the performance of your Deluxe Select+ rear shock.
