• Perform service every 100 hours of riding (less depending on riding conditions and riding style).
• Regular maintenance ensures your RockShox suspension fork performs as it should.
• For dust seal, foam ring, oil seal, and bushing removal and installation, please reference the Bushing Service Guide.
• Right side equals rider’s right; left side equals rider’s left.
G E T T I N G S TA R T E D
1. Remove fork from bicycle.
2. Spray entire fork with isopropyl alcohol and wipe all dirt and mud from fork. Clean around dust seals and upper tubes.
3. Lay tools out on work bench, and create a clean work area for internals service.
4. Place oil pan under fork on floor.

Air Spring Tuning
With independently adjustable positive (top) and negative (bottom) air chambers, the air spring system of your Pike
Air fork can be easily tuned for your weight and riding style. Use the following instructions as a starting point. If further fine tuning is desired, follow the hints at the end of this section.
Step 1 - Selecting Positive Air Pressure
Positive air pressure determines the amount of force required to compress your fork. More positive air pressure results in less suspension sag and higher bottom out forces. Less positive air pressure results in more suspension sag and lower bottom out forces. Using the chart below as a guide, inflate the positive air chamber to the desired pressure.

Step 2 - Selecting Negative Air Pressure
Negative air pressure effects the amount of force required to initiate suspension travel. Negative air pressure works with bump input AGAINST the force of the positive air chamber. More negative air pressure results in a suspension set-up that is more active, especially to small bump input. Less negative air pressure results in a suspension set-up does not move or "bob" under rider input or small bumps. Start with pressure equal to positive pressure, and decrease or increase as desired. More negative pressure = more active initial compression stroke. Adjust as needed to achieve the desired compression stroke.

AIR LOSS
• Inspect air piston o-rings. Replace if necessary.
• To avoid air loss, remove Dual Air top cap and check oil level inside air chamber, every 25 to 50 riding hours. If there is little or no oil on top of air piston o-ring, pour 3 to 5cc RockShox 15wt suspension oil into air spring chamber. Oil will keep air seal lubricated.
• Inspect schrader valve assembly. Replace if damaged or malfunctioning. Clean if clogged.
LOSS OF, OR VARIANCE IN DAMPING
• Inspect all damper o-rings. Replace and lubricate.
• Inspect damper oil volume. Remove damper top cap/compression damper assembly. Add or remove oil as needed.
• Remote: Inspect remote cable tension. Cable may stretch, or become loose. Loosen cable screw, tension cable and tighten. Test.
Adjust as needed.
COMPRESSION STROKE NOT SMOOTH
• Remove both shaft bolts. Pull lowers down about an inch. Allow oil to drain. Inject or pour 15cc of fresh suspension oil into lower leg through shaft bolt holes.
• Lubricate upper tubes near dust seals. Press down on fork a few times. Wipe away excess lubricant.
BUSHING PLAY
• Inspect and replace worn bushings. Bushings are a wear and tear item, and need to be replaced after approximately 100 to 200 riding hours, depending your riding style, condition, riding time and body weight. If you ride a lot, check those bushings!
• See the 'Bushing Installation' guide at www.rockshox.com for procedures.
OIL LOSS
• Inspect the air piston o-ring for air bypass. If there is a repeated loss of air pressure, air may be the cause of oil loss at the left dust seal.
• Inspect your shaft bolt crush washers. Replace if worn or damaged.
• Inspect your top cap o-rings. Replace if torn or knicked.
