What pressure should I use in the front suspension?

Why is Front Suspension Important?

Front suspension plays a crucial role in providing a smooth and comfortable ride on a bike. It absorbs impacts from rough terrain, such as bumps, rocks, and roots, allowing the rider to maintain control and stability. But how do you determine the right amount of pressure to use in the front suspension?


Factors to Consider

Several factors come into play when deciding the appropriate pressure for your front suspension:

  • Rider Weight: Heavier riders generally require higher pressure to prevent excessive sag and bottoming out.
  • Riding Style: Aggressive riders who tackle challenging trails may prefer a firmer suspension setup, while casual riders may opt for a softer setup.
  • Terrain: The type of terrain you ride on also influences the ideal suspension pressure. Rougher terrain calls for higher pressure to handle the impacts effectively.

Recommended Pressure Range

While the specific pressure may vary depending on the bike model and suspension design, a general guideline for front suspension pressure is to aim for 20-30% sag. Sag refers to the amount the suspension compresses under the rider's weight.

Here's a step-by-step process to set the pressure:

  1. Start with the recommended pressure range provided by the bike manufacturer.
  2. Set your suspension to the midpoint of the recommended range.
  3. Put on your riding gear and get on the bike in a normal riding position.
  4. Have a friend measure the distance between the o-ring or zip tie on the fork stanchion and the dust seal.
  5. Get off the bike and measure the sag distance. It should be around 20-30% of the total fork travel.
  6. If the sag is too low, increase the pressure slightly. If it's too high, decrease the pressure.
  7. Repeat the process until you achieve the desired sag.

Importance of Regular Maintenance

Remember that suspension settings may need adjustment over time due to wear and changes in riding conditions. It's essential to regularly check and fine-tune the pressure to ensure optimal performance and safety.


Setting the right pressure in the front suspension of your bike is crucial for a comfortable and controlled ride. Consider your weight, riding style, and terrain to determine the appropriate pressure range. Aim for 20-30% sag and make adjustments as needed. Regular maintenance and fine-tuning will help you enjoy the full benefits of your front suspension.
