Key Features

• Real-time Mechanical Calculation: Calculates recommended air pressure (PSI) based on front-fork static load distribution (~45%) derived from combined rider and bike weight.
• Riding Style Customization: Dynamically adjusts pressure and compression profile according to target sag settings: 20% for XC (Firm), 25% for All-Mountain (Balanced), and 30% for Enduro/DH (Plush).
• Interactive Visual Fork Animation: Provides an immediate visual representation of stanchion compression and red O-ring movement as you adjust weights or riding styles.
• Unit Switching: Seamlessly toggles between Metric (kg) and Imperial (lbs) units with automatic slider scale recalibration.

2. Adjust Weights: Drag the sliders to match your gear-equipped rider weight and your bike’s overall weight.
3. Choose Riding Style: Select your preferred style (XC / Trail, All-Mountain, or Enduro / DH) to apply the target sag percentage.
4. Check Results: Review the recommended PSI and observe the live stanchion compression in the visual widget below.
