Key Features

• Silky Smooth Damping: Maxima Plush fluid minimizes friction and reduces damper noise for a quiet and responsive ride.
• Consistent Coil-Like Feel: The highly adjustable DebonAir spring provides a uniform and predictable feel throughout the shock's travel.
• Customizable Piston Tuning: Separate, independent open and threshold pistons allow for precise tuning tailored to individual riding preferences.
• Fine-Tune Compression: Low Speed Compression adjustment enables riders to fine-tune damping from the base setting for optimal control.

Setup

Initial Setup: Air Pressure and Sag

Proper sag setting is critical for optimal suspension performance. The DebonAir spring allows for precise air pressure adjustments to match rider weight and riding style. Refer to your bike manufacturer's recommendations for sag percentage, typically between 25-35% of the shock's travel.

Compression Adjustment (RCT Damper)

The RCT damper provides control over Rebound, Compression, and Threshold. The Low-Speed Compression (LSC) dial allows for fine-tuning of the shock's resistance to slow shaft speeds, affecting chassis stability and traction. Turn the dial clockwise for more compression damping (firmer) and counter-clockwise for less (softer).

Rebound Adjustment

Rebound damping controls the speed at which the shock extends after being compressed. Adjusting rebound prevents harsh top-outs and helps maintain tire contact with the ground over successive bumps. The rebound dial is typically marked with a rabbit (faster) and turtle (slower) icon. Turn clockwise for slower rebound and counter-clockwise for faster rebound.

Operating

Once properly set up, the SuperDeluxe Ultimate RCT is designed to provide consistent and reliable performance across varied terrain. Utilize the firm threshold adjustment for increased pedaling efficiency during climbs and switch to the open mode for maximum suspension travel and comfort during descents. Experiment with settings to find the optimal balance for your riding style and trail conditions.

Maintenance

Cleaning

Regular cleaning of your rear shock is essential to prevent dirt and debris from damaging seals and affecting performance. Use mild soap and water to clean the shock body, shaft, and seals. Avoid using high-pressure washers directly on seals or bearings, as this can force contaminants inside.

Service Intervals

For sustained performance, safety, and longevity, regular service by a qualified technician is recommended. Consult the official RockShox service manual or website for detailed service intervals and procedures specific to your shock model. Timely service ensures all internal components, fluids, and seals are in optimal condition.

Troubleshooting

If you experience issues such as inconsistent damping, loss of air pressure, or unusual noises, first re-check your air pressure and adjustment settings according to the setup instructions. Ensure all mounting bolts are torqued to the manufacturer's specifications. If problems persist after these checks, it is recommended to contact an authorized RockShox service center or a professional bike mechanic for diagnosis and repair.
