The RockShox Super Deluxe Select+ rear shock is a popular choice among mountain bikers, thanks to its advanced design, reliable performance, and customizable features. However, even the best components can experience issues over time. In this guide, we’ll explore common problems you might encounter with the Super Deluxe Select+ rear shock and provide solutions for troubleshooting and fixing them.
1. Sag Issues
Understanding Sag
Sag refers to the amount the shock compresses under the rider’s weight. If your Super Deluxe Select+ is sagging too much or too little, it can significantly affect your bike’s handling and performance.
Troubleshooting Sag Issues
- Too much sag: If the rear shock feels too soft or you notice excessive sag during rides, it may indicate that the shock is too soft for your weight. This can be corrected by adjusting the air pressure. Solution:
- Check the recommended air pressure range on the shock’s sticker or manual.
- Using a shock pump, increase the air pressure in small increments (5-10 PSI at a time).
- Re-test the sag after each adjustment and aim for approximately 25-30% sag, depending on your riding style and weight.
- Too little sag: If the shock is too stiff or doesn’t compress enough, it could be due to too much air pressure. Solution:
- Use a shock pump to release small amounts of air.
- Recheck the sag after each adjustment.
If the issue persists after adjusting air pressure, it could be an indication that the shock is damaged or needs servicing.
2. Rebound Damping Problems
Rebound Issues
Rebound damping controls the speed at which the shock returns after compression. Too fast or too slow rebound can affect the stability and comfort of your bike’s rear end.
Troubleshooting Rebound Damping Problems
- Too fast rebound: If the rear shock is bouncing back too quickly after compression, it may cause a “pogo stick” effect, making the bike feel unstable. Solution:
- Adjust the rebound knob (typically located at the bottom of the shock).
- Turn it clockwise to slow the rebound, helping the shock return more smoothly and in a controlled manner.
- Too slow rebound: If the shock feels sluggish or doesn’t return to full extension after compression, it may lead to a harsh ride. Solution:
- Turn the rebound knob counterclockwise to increase the rebound speed.
- Test the rebound after each adjustment to ensure proper functionality.
If adjustments don’t resolve the issue, the shock might require servicing, especially if it feels “stuck” or resistant to movement.
3. Compression Damping Issues
Understanding Compression Damping
Compression damping determines how much resistance the shock provides when it compresses under force. Too much or too little compression damping can make the bike feel either overly stiff or too soft.
Troubleshooting Compression Damping Problems
- Too soft compression: If the rear shock compresses too easily and bottoms out frequently, this may be due to low compression damping. Solution:
- Adjust the compression knob (usually located on the top of the shock).
- Turn it clockwise to increase the compression damping and provide more resistance against compression.
- Too stiff compression: If the shock feels too stiff or doesn’t compress easily, it could be due to excessive compression damping. Solution:
- Turn the compression knob counterclockwise to reduce damping and allow the shock to compress more freely.
After making adjustments, test the shock on different terrain to assess whether the desired compression damping balance has been achieved.
4. Leaking Oil or Air
Identifying Leaks
If your Super Deluxe Select+ rear shock is leaking oil or air, this could severely impact its performance, leading to a loss of pressure, poor damping, or an inconsistent ride.
Troubleshooting Leaks
- Air leaks: If you notice the air pressure dropping over time, the shock may be losing air through the valve or seals. Solution:
- Inspect the valve and ensure it is securely tightened.
- If air continues to leak, check for any visible damage or wear on the shock seals. If damaged, the seals may need to be replaced.
- Oil leaks: If there is visible oil around the shock body, it could indicate a seal failure or an issue with the shock’s internals. Solution:
- Immediately stop using the shock and avoid riding it until it is serviced.
- Send the shock to an authorized RockShox service center for inspection and repair.
5. Noisy Shock
Diagnosing Noise Issues
Sometimes, the shock may produce unwanted noises like squeaks, creaks, or knocking sounds. These noises can occur due to a number of reasons, such as dry bushings, loose bolts, or excessive friction.
Troubleshooting Noisy Shock
- Squeaking or creaking: This is often caused by friction between the shock’s moving parts or lack of lubrication. Solution:
- Check if the shock is properly lubricated and apply appropriate lubricant to the shock’s moving parts.
- Ensure all bolts and components are properly tightened.
- Knocking noises: Knocking sounds usually result from the shock’s mounting hardware or internal damage. Solution:
- Inspect the shock’s mounting hardware and ensure it is secure.
- Check for any signs of damage to the shock’s internals or bushings. If the knocking persists, consider sending the shock in for servicing.
6. Inconsistent Performance
Identifying Performance Issues
Inconsistent performance, such as the shock feeling “spongy” or unresponsive, could stem from incorrect settings or internal damage.
Troubleshooting Performance Issues
- Incorrect settings: Double-check the settings for air pressure, compression, and rebound. Solution:
- Adjust the settings as per your rider weight and riding style.
- Make sure all dials are in the proper range for your riding terrain.
- Internal issues: If the shock feels unresponsive or overly soft despite correct settings, it could indicate a problem with the internal components, such as a lack of oil or a broken internal spring. Solution:
- Take the shock to a certified RockShox technician for internal servicing.
7. Compatibility Issues
Ensuring Compatibility
It’s essential to ensure that the Super Deluxe Select+ rear shock is compatible with your bike’s frame and other components. An incompatible shock can result in poor performance or even damage.
Troubleshooting Compatibility Issues
- Incorrect shock size: If the shock is too long or too short for your frame, it can cause issues with travel, geometry, and overall bike handling. Solution:
- Double-check the shock size against your bike’s specifications.
- Ensure the shock’s eyelet width and length are correct for your frame’s rear suspension design.
- Mounting hardware: Ensure that the shock’s mounting hardware matches your bike’s frame requirements. Solution:
- If the hardware is incompatible, consider getting custom adapters or hardware to ensure a secure fit.
If you’re unsure about compatibility, consult your bike’s manufacturer or an experienced bike mechanic for guidance.
