Tools Required
- Torque wrench [paid link] with appropriate bits (4mm, 5mm, 6mm hex)
- Shock pump with pressure gauge
- Suspension grease and RockShox-recommended fluids
- Clean rags and isopropyl alcohol
- Measuring calipers or ruler
- Allen key set
- Oil syringe or bleed kit [paid link] (for lower leg service)
- Pick tool for seal removal
Installation of the Pike Ultimate Charger 3
Correct installation is crucial to fork performance and longevity. Begin by preparing the steerer tube—cut it to fit your frame and headset stack height, then install the star nut or threaded insert (for ZS headsets). Apply a light layer of grease to the headset cups and install the fork into the frame.
Ensure the crown race is seated correctly before torquing the stem and headset preload. The front wheel must be installed with the Maxle Stealth axle or Maxle Ultimate, depending on the model, ensuring it’s torqued to the recommended 9 Nm.
Before you proceed to setup, confirm the rotor is aligned with the caliper and the caliper bolts are torqued to 6.2 Nm. Improper alignment here can lead to uneven braking or rotor rub.
Initial Suspension Setup
The Pike Ultimate Charger 3 features independent adjustments for air spring pressure, high- and low-speed compression, and rebound. Begin by setting your sag. This is typically 20-30% of the fork’s total travel.
Inflate the DebonAir+ air spring using a shock pump. For most riders, a starting point of 80-100 psi is suitable for a 70–85 kg body weight. Adjust as needed based on sag measurement. Sit on the bike in full gear, and use an o-ring or zip tie to measure travel used under body weight.
Next, adjust the rebound using the red dial on the bottom of the right fork leg. Turn clockwise to slow the rebound; counterclockwise to speed it up. A neutral baseline is about 8 clicks out from fully closed.
Adjusting Compression Settings
The Charger 3 damper provides High-Speed Compression (HSC) and Low-Speed Compression (LSC) controls. HSC affects fork performance during big hits or landings. LSC influences fork motion during pedaling and smaller trail impacts.
To begin, set HSC to the middle position (3 out of 5 clicks) and LSC slightly softer (2 out of 5 clicks). From there, fine-tune based on terrain:
- For aggressive, fast descents: Increase HSC and LSC by 1–2 clicks to reduce bottom-out.
- For technical climbing or flat trails: Reduce LSC for better small bump compliance.
Always make changes in small increments and test ride to evaluate effects.
Maintenance Intervals and Procedures
Keeping the Pike Ultimate Charger 3 in peak condition requires routine maintenance. RockShox recommends a lower leg service every 50 hours and a full damper and air spring service every 200 hours.
Lower Leg Service Steps:
- Remove the lowers using a 5mm Allen wrench [paid link] after draining any residual oil.
- Clean and inspect the seals, bushings, and internal stanchions.
- Re-lubricate the dust wipers with RockShox grease.
- Inject 10ml of 0W-30 suspension oil into each leg.
- Reinstall and torque the bolts to 7 Nm.
Check for signs of oil leakage or excessive bushing play. Replace seals if there’s consistent contamination or stiction.
Troubleshooting Setup Issues
Several common issues can arise if setup is not dialed properly:
Harsh Feeling Fork: May indicate too much air pressure or excessive compression damping. Reduce pressure by 5 psi or soften compression by 1–2 clicks.
Fork Diving Too Much: Often caused by too little air pressure or low-speed compression being too open. Add air or increase LSC.
Top-Out Knock: If the fork feels like it extends too harshly, slow down rebound or check for low air pressure.
Excessive Stiction: Usually due to dry seals or dirty bushings. Perform a lower leg service and apply fresh lubrication.
Customization and Performance Tuning
The Pike Ultimate Charger 3 allows a high degree of customization. One effective method is using volume spacers to adjust spring curve progression. Adding spacers increases mid-stroke support and bottom-out resistance.
Each Pike fork can accommodate 1–5 tokens depending on travel and rider preference. For aggressive riding, 2–3 tokens often yield a better ramp-up feel.
Additionally, pairing your fork settings with tire pressure, wheel choice, and rear suspension characteristics can further refine performance. Use a setup log to track changes and results for consistency.
Compatibility with Other Drivetrain and Suspension Components
The Pike Ultimate Charger 3 is compatible with both mechanical and electronic drivetrains, including SRAM AXS systems. It is designed for 29” and 27.5” wheel sizes with 110mm Boost spacing.
Ensure rotor size compatibility with the fork’s post mount (160mm native). Adapters can be used for larger rotors, such as 180mm or 200mm.
For rear suspension synergy, use RockShox Super Deluxe or Deluxe rear shocks to match damping characteristics, though other brands like Fox and DVO are functionally compatible when properly tuned.
Comparing Pike Ultimate Charger 3 to Similar Forks
Compared to the RockShox Lyrik or the Fox 34 Factory GRIP2, the Pike Ultimate Charger 3 sits between trail and enduro. It offers slightly less chassis stiffness than the Lyrik but more agility for tight terrain.
The Fox 34 GRIP2 is slightly more sensitive to small bumps, while the Pike excels in mid-stroke support. For riders prioritizing climbing efficiency and descent control, the Pike strikes a strong balance.
Additionally, the Charger 3 damper’s independent circuits offer more usable range than older Charger 2.1 systems, and better oil flow consistency for longer descents.
Frequently Asked Questions
1. How do I know if my air pressure is set correctly in the Pike Ultimate Charger 3?
Measure sag with your full riding gear. Aim for 25% of travel used while in a neutral riding position. Adjust pressure accordingly.
2. Can I install a fender on the Pike Ultimate Charger 3?
Yes. The fork includes threaded mounts on the arch for RockShox-specific bolt-on fenders.
3. What is the difference between High-Speed and Low-Speed Compression?
High-speed controls big hits like jumps or drops. Low-speed affects fork behavior during braking, cornering, and pedaling forces.
4. How often should I service the Charger 3 damper?
Perform a full damper service every 200 hours of riding, or sooner if the fork feels inconsistent or makes unusual noises.
5. Can I use this fork for bikepacking or loaded touring?
While it’s designed for aggressive trail riding, it can handle bikepacking loads if proper air pressure and rebound settings are applied to account for extra weight.
6. What’s the maximum tire clearance for this fork?
The Pike Ultimate Charger 3 allows clearance for up to 2.6” wide tires on both 27.5” and 29” models.
Conclusion
Tuning the RockShox Pike Ultimate Charger 3 suspension fork isn’t just for pro mechanics—it’s a vital part of achieving peak trail performance. By carefully setting air pressure, dialing in compression and rebound, and maintaining regular service intervals, riders can ensure consistent handling, improved comfort, and better control. Whether you’re an enthusiastic beginner or a seasoned trail rider, understanding your fork’s full potential starts with thoughtful setup and maintenance.
