The RockShox Pike Select+ is a premium suspension fork designed for trail and enduro riders. Known for its smooth performance and adjustable features, the Pike Select+ offers a highly customizable riding experience. However, like any high-performance component, it can occasionally develop issues that hinder its optimal performance. This guide covers the most common problems riders may face with the Pike Select+ and provides step-by-step instructions for troubleshooting and resolving them.
Fork Not Returning to Full Travel
Possible Cause: Insufficient Air Pressure
One of the most common issues with the Pike Select+ is the fork not returning to full travel after a ride. This is often caused by insufficient air pressure in the positive air chamber. When the air pressure is too low, the fork struggles to rebound fully, affecting its performance.
How to Fix It:
- Check the Air Pressure: Use a high-quality shock pump to measure the air pressure in the positive air chamber. Compare the reading to the recommended pressure settings based on your weight and riding style.
- Adjust the Pressure: If the pressure is too low, inflate the fork to the recommended pressure level. Ensure that the pump is securely connected to avoid air leakage during inflation.
- Test the Fork: After adjusting the air pressure, compress the fork several times to test if it returns to full travel.
If the problem persists after adjusting the air pressure, consider checking the fork’s seals for wear or damage.
Unresponsive Damping Adjustments
Possible Cause: Air or Fluid Contamination
If the damping adjustments on your Pike Select+ are unresponsive or inconsistent, it could be due to air or fluid contamination in the damper. Over time, dirt, moisture, or debris can enter the fork, affecting the performance of the damping system.
How to Fix It:
- Check for Leaks: Inspect the damper for any visible signs of oil leakage. Leaks often occur around the seals or damper body.
- Clean the Fork: Thoroughly clean the fork to remove any dirt or debris that could be affecting the damping system. Use a clean cloth and a gentle solvent to wipe down the fork’s exterior.
- Flush the Damper: If cleaning does not resolve the issue, it may be necessary to flush the damper. This can be done by removing the damper assembly and draining any contaminated fluid. Replace the oil with fresh, recommended suspension fluid.
- Reassemble and Test: Once the damper has been cleaned and reassembled, test the fork by adjusting the compression and rebound settings. Check if the adjustments respond as expected.
If these steps do not resolve the issue, the damper may need a full rebuild.
Fork Bottoming Out Too Easily
Possible Cause: Incorrect Air Pressure or Spring Rate
Fork bottoming out occurs when the fork compresses too far, hitting the lower limit of its travel. This issue is typically caused by incorrect air pressure or an inappropriate spring rate for the rider’s weight and riding style.
How to Fix It:
- Check the Air Pressure: Ensure the air pressure is set correctly based on your weight and the type of terrain you’re riding. A shock pump should be used to get an accurate reading.
- Adjust the Air Pressure: If the fork is bottoming out too easily, increase the air pressure slightly. This will provide more support during compression.
- Check the Spring Rate: If increasing the air pressure doesn’t solve the issue, consider switching to a different air spring with a higher spring rate. A stiffer spring can provide better bottom-out resistance.
- Test the Fork: After making adjustments, test the fork by riding it on terrain that typically causes bottoming out. Check if the fork compresses properly without hitting the travel limits.
Sticking or Grinding Sensation During Compression
Possible Cause: Damaged Bushings or Dirt in the Stanchions
A sticking or grinding sensation during compression often points to a problem with the fork’s bushings or dirt in the stanchions. When the fork’s bushings wear down or dirt gets trapped in the stanchions, it can lead to a rough feeling when the fork compresses.
How to Fix It:
- Clean the Stanchions: Use a clean, dry cloth to wipe the stanchions and remove any visible dirt or debris. You can also use a suspension cleaner to help remove grime.
- Inspect the Bushings: Check the fork’s bushings for any signs of wear or damage. If the bushings are excessively worn, they may need to be replaced.
- Lubricate the Stanchions: Apply a small amount of suspension-specific lubricant to the stanchions. This will ensure smooth movement and help prevent any sticking or grinding sensations.
- Test the Fork: After cleaning and lubricating, test the fork by compressing it slowly. If the problem persists, the bushings may need to be replaced.
Excessive Fork Movement During Descents
Possible Cause: Loose or Worn-Out Components
Excessive fork movement, such as unwanted bobbing or poor control during descents, is typically caused by loose or worn-out components in the fork’s system. This can occur with the damper, air spring, or even the headset.
How to Fix It:
- Check the Damper Settings: Make sure the compression setting is appropriate for the terrain you’re riding. For steep descents, you may need to increase the compression to prevent excessive fork movement.
- Inspect the Headset: Loose headset bearings or a loose fork crown can contribute to excessive fork movement. Tighten the headset and ensure the fork is securely installed in the frame.
- Examine the Air Spring: If the air spring is too soft, it may cause the fork to dive excessively. Increase the air pressure in the fork to provide more support and prevent excessive movement.
- Test the Fork: After making these adjustments, take the bike for a test ride on a descent. Ensure the fork remains stable and controlled during the ride.
Noisy Fork or Popping Sounds
Possible Cause: Air in the Damper or Air Spring
A common issue with suspension forks like the Pike Select+ is the production of popping or creaking sounds, which can be caused by air in the damper or air spring. These noises may occur when the fork is under load or during compression and rebound cycles.
How to Fix It:
- Check for Air Leaks: Inspect the fork for any visible signs of air leakage, particularly around the air spring or damper seals.
- Re-balance the Air Spring: If air has become trapped in the system, it may be necessary to re-balance the air spring. You can do this by gently cycling the fork through its travel while adjusting the air pressure.
- Lubricate the Seals: Apply a small amount of suspension grease to the fork seals to help reduce friction and minimize noise during movement.
- Test the Fork: After completing these steps, ride the bike and listen for any unusual noises. If the noise persists, it may indicate a more serious issue, such as a damaged seal or air chamber.
Conclusion
The RockShox Pike Select+ is a highly advanced suspension fork that provides excellent performance for trail and enduro riders. However, like any mechanical component, it is subject to wear and tear, and occasional issues may arise. By following the troubleshooting steps outlined in this guide, you can address common problems such as unresponsive damping, fork bottoming out, and excessive noise. Regular maintenance, proper adjustment, and timely repairs will help ensure that your Pike Select+ fork continues to perform at its best, providing a smooth and controlled ride on any terrain.
