Once installed, adjusting the Fenix AIR rear shock for optimal performance is crucial. The Fenix AIR offers multiple adjustment points, allowing riders to tailor the suspension settings to their specific needs.

Air Pressure Adjustment

The Fenix AIR features an air-spring system, which means that air pressure plays a critical role in determining the shock’s overall feel and performance. Adjusting the air pressure based on your weight and riding style ensures that the shock can handle different trail conditions effectively.

• Setting the Sag:
  • Start by adjusting the air pressure to the manufacturer’s recommended setting, typically between 180-220 PSI for most riders.
  • Sit on the bike in your riding position and measure the amount of sag (the distance the shock compresses under your weight). A general rule of thumb is to aim for around 25-30% sag.
  • Adjust the air pressure to achieve this target sag. If the sag is too deep, increase the pressure, and if it is too shallow, decrease the pressure.

Rebound Adjustment

Rebound damping controls how quickly the shock returns to its extended position after compression. For smoother rides, a moderate rebound setting is ideal.

• Turn the rebound adjuster counterclockwise to slow down the return or clockwise to speed it up.
• Start with the middle setting and fine-tune according to trail conditions. Faster rebound may be useful on smoother roads, while slower rebound can enhance control on rougher terrain.

Compression Adjustment

The compression setting on the Fenix AIR rear shock helps you adjust how much resistance the shock offers when it is compressed. It is typically adjustable via low-speed and high-speed compression knobs.
