Rebuilding the RockShox Pike Select+ suspension fork is an essential maintenance procedure for ensuring peak performance, longevity, and comfort during rides. Whether you’re looking to restore its original feel or address specific issues, following this step-by-step guide will help you navigate the process with confidence. This article covers everything you need to know about the Pike Select+ fork, including its components, tools, and a thorough rebuild process.
Understanding the Pike Select+ Suspension Fork
The RockShox Pike Select+ is designed for aggressive trail riding, offering a balanced blend of performance, adjustability, and reliability. It features an advanced DebonAir spring system and a Charger 2.1 damper, allowing riders to fine-tune both compression and rebound settings. Over time, fork components can wear down or lose their intended performance due to usage, dirt, and weather conditions. Regular maintenance and rebuilds are crucial for maintaining the smooth, responsive action you rely on during your rides.
Tools Required
Before you begin, ensure you have the following tools on hand to perform a proper rebuild:
- 8mm, 10mm, and 15mm Allen wrenches [paid link]
- Torque wrench [paid link] with appropriate settings (for fork assembly)
- 24mm and 32mm spanner wrenches
- T25 Torx wrench [paid link]
- Suspension fluid (check RockShox specifications for the correct type and amount)
- Replacement seals and o-rings
- 7mm and 10mm sockets
- Rags for cleaning
- Shock pump (for air pressure adjustments)
- Suspension grease
- Fork oil or fluid for damper and spring lubrication
- Specialized fork seal tool (optional but helpful)
Step 1: Preparing the Fork for Rebuild
Before diving into the rebuild, ensure your bike is properly secured, and your fork is clean. Place your bike in a stand or on a flat surface.
- Remove the wheel, brake calipers, and any accessories attached to the fork.
- Use a rag to wipe down the fork stanchions to remove any dirt or debris. This ensures no contaminants enter the fork during the rebuild process.
- Release any air from the fork using the valve at the top of the air spring.
Step 2: Remove the Fork from the Bike
Now that the fork is cleaned and ready, it’s time to disassemble it.
- Loosen the headset clamp bolts using the appropriate size Allen wrench [paid link].
- Remove the fork from the frame, ensuring that the steerer tube is free of any remaining components like the crown race.
- Place the fork in a stable position with the dropouts facing upward, preparing it for disassembly.
Step 3: Disassemble the Pike Select+ Fork
To access the internal components of the Pike Select+, you must remove the lowers and disassemble the air spring and damper.
- Remove the Damper and Air Spring Assembly:
- First, use the appropriate wrenches to remove the air spring assembly. This is typically held in place by the top cap. Carefully unscrew the cap using an 8mm Allen wrench [paid link] and remove the assembly from the stanchions.
- Next, remove the damper using a 24mm spanner wrench. Keep track of the order of components, as it’s essential for reassembly.
- Remove the Lowers:
- Use a 32mm spanner wrench to loosen and remove the lower legs of the fork.
- Once removed, carefully slide the lowers off the stanchions. Pay attention to any washers or seals that may come loose during this process.
Step 4: Clean and Inspect the Components
With the fork disassembled, it’s time to clean all the components thoroughly and inspect them for any wear.
- Cleaning:
- Use a rag to clean the stanchions, the lowers, and the internal damper and spring components. Make sure no dirt or contaminants are left on any of the parts.
- For any stubborn debris, use a degreaser compatible with suspension components. Avoid using harsh chemicals that can damage seals.
- Inspection:
- Check the seals, o-rings, and bushings for signs of wear or damage. If any seals appear cracked or compromised, it’s a good idea to replace them during the rebuild.
- Inspect the stanchions for scratches, dents, or other damage that could affect performance. If you notice any, contact a qualified technician to evaluate if the fork requires professional repairs.
Step 5: Replace Seals and O-Rings
Over time, the seals and o-rings in your Pike Select+ fork can degrade and cause air or oil leaks, which directly affect performance. Replacing these parts during a rebuild will ensure smooth operation.
- Carefully remove the old seals and o-rings from the fork components. Use a seal tool if necessary.
- Grease the new seals lightly with suspension grease before installing them into their respective grooves.
- Ensure that each seal is properly seated and aligned.
Step 6: Reassemble the Pike Select+ Fork
Now that the components are cleaned and inspected, and the new seals are in place, it’s time to reassemble the fork.
- Install the Air Spring and Damper:
- Carefully reinstall the air spring assembly into the fork stanchions, ensuring it is securely seated. Tighten the top cap with the 8mm Allen wrench to the recommended torque specification.
- Install the damper back into the fork, making sure the lower legs are aligned with the stanchions. Tighten the damper bolt using the 24mm spanner wrench.
- Reinstall the Lowers:
- Slide the lower legs back onto the stanchions and ensure that the seals are properly aligned.
- Tighten the lower leg bolts using the 32mm spanner wrench to the correct torque specification, which ensures a firm but not overly tight fit.
Step 7: Add Suspension Fluid and Set Air Pressure
Once reassembled, it’s time to refill the suspension fluid and adjust the air pressure.
- Suspension Fluid:
- Use the recommended suspension oil or fluid for the Pike Select+ and add it to the lowers and damper assembly as per the RockShox specifications.
- Ensure the correct volume of fluid is added to the lowers to maintain proper damping performance.
- Set Air Pressure:
- Using a shock pump, add air to the air spring chamber according to the recommended pressure based on your weight and riding style. Check the owner’s manual for the ideal settings.
Step 8: Perform Final Adjustments
With the fork fully reassembled, perform some final checks and adjustments to ensure everything is working as it should.
- Check Rebound and Compression Settings:
- Adjust the rebound and compression settings on the damper to suit your riding preferences. The Pike Select+ provides a variety of tuning options, so fine-tune these settings for optimal ride quality.
- Inspect for Leaks:
- Before reinstalling the fork on your bike, check for any air or oil leaks by compressing the fork a few times and observing the seals.
- Reinstall the Fork on the Bike:
- Carefully reinstall the fork into the bike frame, securing the headset and tightening the bolts to the recommended torque values.
- Reattach the wheel and brake calipers, and check the brake rotor alignment.
Step 9: Test Ride and Fine-Tuning
After completing the rebuild, take your bike for a short test ride to ensure everything is functioning properly. Pay attention to any unusual sounds, excessive rebound, or sag. Make adjustments to the suspension settings as needed to achieve your desired performance.
Troubleshooting Common Set-Up Issues
- Fork Stiffness: If the fork feels too stiff or too soft, check the air pressure and adjust accordingly. Adding or releasing air from the spring chamber will help balance the feel.
- Unresponsive Rebound: If the rebound is not functioning as expected, ensure that the damper is properly installed and that no fluid leakage has occurred.
- Oil Leaks: Leaking oil is often caused by damaged seals or o-rings. If leaks persist after a rebuild, replace the affected seals and check for wear in the internal components.
Conclusion
Rebuilding your RockShox Pike Select+ suspension fork is a vital maintenance task that helps maintain peak performance and extends the life of your fork. By following this guide, you can keep your Pike Select+ fork running smoothly and efficiently. Regular upkeep ensures better handling, a more comfortable ride, and fewer issues on the trail.
