The RockShox Pike Ultimate Charger 3 represents the latest evolution of the Pike series, engineered for aggressive trail and all-mountain riding. Featuring RockShox’s new Charger 3 damper and ButterCups vibration-reduction technology, this fork is designed to deliver unmatched sensitivity, control, and rider confidence. This guide will cover everything from installation and tuning to maintenance and model comparisons, helping riders determine whether this fork is the best choice for their setup.

Tools Required

  • Torque wrench [paid link] with compatible bits
  • Crown race setting tool
  • Star nut setter or threaded insert tool
  • Allen wrenches [paid link] (4mm, 5mm, 6mm)
  • Suspension pump
  • Measuring tape or caliper
  • RockShox-specific lower leg removal tools
  • Suspension grease and oil (as per service manual)

Installation of the Pike Ultimate Charger 3

Correct installation is crucial to ensure the fork performs as intended. The Pike Ultimate Charger 3 comes in both 29” and 27.5” configurations with various offset options.

Begin by ensuring your frame is compatible with the steerer tube diameter and fork travel range. The Pike Ultimate features a 1.5” to 1-1/8” tapered steerer, which fits most modern mountain bikes.

After cutting the steerer tube to the correct length, install the star nut or threaded insert depending on your headset system. Press the crown race onto the steerer tube using a crown race setter, ensuring a flush fit. Grease the headset cups, then insert the fork into the head tube. Adjust the preload cap, stem, and spacers, tightening everything to the manufacturer’s torque specs.

Check clearance between the fork arch and the tire. For 29” wheels, ensure your tire doesn’t exceed maximum clearance recommendations.

Initial Setup and Suspension Adjustment

Setting the correct air pressure and damper settings is essential for optimal performance. The Pike Ultimate Charger 3 offers an updated DebonAir+ spring and the new Charger 3 damper, which features truly independent high-speed compression, low-speed compression, and rebound circuits.

Use RockShox’s air spring chart as a baseline for pressure, based on rider weight. Attach the shock pump and inflate the positive air chamber. The new DebonAir+ allows for greater mid-stroke support while maintaining small bump sensitivity.

For damping:

  • Set rebound using the red dial on the bottom of the right leg. Adjust until the fork returns smoothly after compression.
  • High-speed compression (HSC) and low-speed compression (LSC) are adjusted via knobs on the top of the right leg. Start with middle settings, then refine based on trail feedback.

Routine Maintenance Schedule

Routine maintenance keeps the Pike Ultimate performing at its peak. RockShox recommends the following service intervals:

  • Every 25 hours: Clean stanchions and dust seals, inspect for oil residue.
  • Every 50 hours: Lower leg service including foam ring lubrication and oil replacement.
  • Every 200 hours or annually: Full damper and air spring service.

When removing the lower legs, use the correct socket to loosen bolts, then gently slide off the lowers. Clean and re-lubricate foam rings and seals using suspension-specific grease. Replace the lower leg oil per RockShox specs. Always reinstall bolts to the specified torque.

Troubleshooting Common Issues

Common issues with the Pike Ultimate Charger 3 are often related to setup inconsistencies or wear.

  • Excessive sag or bottoming out: Check air pressure and volume spacers. The Pike allows for token installation to adjust progression.
  • Harsh compression feel: Back off HSC and LSC settings incrementally. Too much compression damping can cause stiffness.
  • Rebound too fast or too slow: Adjust red rebound dial. Too fast leads to a pogo effect; too slow causes packing down in successive hits.
  • Oil seepage around seals: Indicates worn seals or overfilled lowers. Perform a lower leg service.
  • Knocking or clicking sounds: Could suggest loose headset, axle, or internal damper issues. Retorque bolts and inspect for wear.

Customization and Performance Optimization

Riders can customize the Pike Ultimate Charger 3 for a tailored ride experience.

  • Volume spacers: Easily added or removed to adjust spring curve. More tokens = more progression.
  • ButterCups: Integrated vibration damping units reduce hand fatigue on long descents.
  • Sag indicator: Utilize the sag gradients on the stanchions to fine-tune pressure on the trail.
  • Offset choices: Available in 37mm and 44mm (for 29”), allowing geometry tuning based on frame and riding style.
  • Fork decals and color options: Custom decals allow matching fork aesthetics to your bike.

Compatibility With Other Drivetrain and Suspension Components

The Pike Ultimate is designed to work seamlessly within SRAM and RockShox ecosystems but is also widely compatible with components from other brands.

  • Front wheel spacing: Available in Boost 15x110mm hub spacing.
  • Brake mounts: Post mount for 180mm rotors, with adapter capability for up to 220mm.
  • Steerer tube: Fits any modern tapered head tube.
  • Travel: Ranges from 120mm to 140mm. Travel can be changed internally with an air spring shaft kit.

Ensure brake hose routing is clean and does not bind during compression. Use zip-tie guides to secure hoses safely.

Comparison With Similar Forks

The Pike Ultimate Charger 3 competes with the FOX 34 Factory and Öhlins RXF34. Each has strengths, but the Pike stands out in several key areas:

  • Weight: Lighter than Öhlins RXF34, close to FOX 34.
  • Damping: Charger 3 offers better independent control than FOX’s FIT4.
  • Maintenance: Tool-free adjusters and easier damper servicing compared to FOX.
  • Ride feel: ButterCups and DebonAir+ deliver more comfort over rough terrain than competitors.

While the FOX 34 may offer marginally better small bump compliance, the Pike Ultimate offers superior mid-stroke support and versatility.

Is the Pike Ultimate Charger 3 Worth It?

For trail riders who demand precision, adjustability, and durability, the Pike Ultimate Charger 3 delivers outstanding performance. Its refinements over previous versions and competitors make it a standout for aggressive trail riding, light enduro use, and even technical XC.

Frequently Asked Questions

1. Can I adjust travel on the Pike Ultimate Charger 3?
Yes, the air spring shaft can be replaced to increase or decrease travel in 10mm increments.

2. How often should I service the Charger 3 damper?
Full damper service is recommended every 200 hours or once a year, depending on riding conditions.

3. Are volume spacers included with the fork?
Yes, most Pike Ultimate models include additional volume tokens for spring curve tuning.

4. Is the Pike Ultimate compatible with eMTBs?
Yes, it is rated for eMTB use within RockShox’s approved guidelines for fork travel and weight.

5. Can I install a 160mm rotor without an adapter?
No, the fork is post-mounted for 180mm minimum rotors. A 160mm rotor would require a negative adapter, which is not standard practice.

6. What’s the difference between Charger 2.1 and Charger 3?
Charger 3 offers fully independent compression circuits, improved adjustability, and a more refined ride feel compared to the older 2.1 model.
