1. Introduksjon
The RockShox SID Ultimate Race Day 2 Suspension Fork is engineered for high-performance cross-country riding. It features a lightweight 35mm chassis and the advanced Charger Race Day 2 3P damper, offering precise control and responsiveness. This manual provides instructions for proper installation, adjustment, and care to ensure optimal performance and longevity of your suspension fork.
2. Oppsett
2.1 Første installasjon
Ensure the fork is correctly installed onto your bicycle frame. This fork features a 1.5-inch tapered steerer tube, 15x110mm Boost thru-axle compatibility, and a 44mm offset. Bolt-in torque cap adapters are included for use with standard hub end caps, facilitating compatibility with various wheelsets.

2.2 Air Pressure Adjustment (DebonAir+)
The DebonAir+ air spring system provides enhanced small-bump sensitivity and mid-stroke support. To set the sag and air pressure:
- Locate the air valve on the top of the left fork leg.
- Consult the air pressure guide (typically found on the fork leg or RockShox website) for recommended pressure based on rider weight.
- Use a high-pressure shock pump to add or release air until the desired pressure is reached.
- Set sag by sitting on the bike in your riding position and measuring the compression of the fork. Adjust air pressure until sag is within the recommended range (typically 15-25% of total travel).
2.3 Damper Settings (Charger Race Day 2 3P)
The Charger Race Day 2 3P damper offers three compression positions:
- Åpne: Provides maximum sensitivity and plushness for rough terrain.
- Pedal: Offers increased compression damping for efficient pedaling on smoother trails and climbs.
- Lockout: Provides a firm platform for climbing or sprinting on paved surfaces.
Adjust the blue compression dial on the top of the right fork leg to select the desired mode. The red rebound dial, located at the bottom of the right fork leg, controls the speed at which the fork extends after compression. Adjust to your preference for control and comfort.

3. Drift
Before each ride, ensure your fork is functioning correctly. Check air pressure, confirm the thru-axle is securely tightened, and verify that the compression and rebound adjustments are set for the terrain you will be riding. Experiment with the three compression positions (Open, Pedal, Lockout) to find the optimal setting for varying trail conditions and riding styles.
4. Vedlikehold
4.1 Rengjøring
After each ride, clean the exterior of the fork, especially the stanchions (upper tubes), with mild soap and water. Wipe dry with a soft cloth. Avoid using high-pressure washers directly on seals, as this can force water and contaminants into the fork.
4.2 Regular Service
Regular service is crucial for maintaining performance and extending the life of your fork. RockShox recommends periodic lower leg services and full damper/air spring services. Refer to the official RockShox service manuals or consult a certified bicycle mechanic for detailed service intervals and procedures. The updated bushing package maximizes bushing overlap, reducing friction and contributing to a smoother ride, but proper lubrication is still essential.
5. Feilsøking
If you experience issues with your SID Ultimate fork, consider the following:
- Tap av lufttrykk: Check the air valve for proper sealing. Ensure the valve core is tight. If pressure loss persists, a seal service may be required.
- Poor Performance/Harsh Ride: Verify air pressure and sag settings. Adjust rebound damping. Ensure the compression dial is not in the Lockout position if you desire full travel.
- Excessive Play/Knocking: Check headset adjustment. Ensure thru-axle is properly tightened. If the issue persists, internal components may require inspection by a qualified mechanic.
For complex issues, it is recommended to contact RockShox customer support or visit an authorized service center.
