How MTB Shock Pressure Influences Your Ride in Different Weather Conditions

One crucial aspect that significantly influences your ride quality is MTB shock pressure. The pressure in your mountain bike’s shocks can determine how well you handle various terrains, the comfort of your ride, and your overall control. Interestingly, weather conditions also play a pivotal role in how your shock pressure behaves and subsequently affects your biking experience. Let’s dive into how different weather conditions influence MTB shock pressure and what adjustments you might need to make.

Understanding MTB Shock Pressure

Before we delve into the weather impacts, it’s essential to understand what MTB shock pressure is. Mountain bikes typically come with either air shocks or coil shocks. Air shocks are more common because they are lighter and easily adjustable. The pressure within these shocks, measured in PSI (pounds per square inch), is crucial for maintaining the desired suspension performance.

Proper shock pressure ensures that the bike’s suspension can absorb impacts effectively, providing a smoother ride over rough terrain and better control during descents. It also prevents bottoming out, where the shock compresses fully and can no longer absorb impacts, which can be damaging and uncomfortable.

Shocks can also have a coil spring. This is a suspension with a more linear damping. What linear means is explained in this blog post. Moreover a detailed comparison between coil and air suspension can be found here.

The Impact of Weather Conditions on MTB Shock Pressure

1. Cold Weather

Cold weather can significantly affect MTB shock pressure. Air contracts when it gets cold, leading to a decrease in pressure inside your shocks.

Adjustment Tip: To counteract the effects of cold weather, you might need to increase your shock pressure slightly before hitting the trails. Regularly check your shock pressure and adjust it to maintain optimal performance. For every 20°C drop around 5 PSI should be added.

2. Hot Weather

Conversely, hot weather causes air to expand, increasing the pressure inside your shocks. Higher shock pressure can lead to a stiffer suspension, making your ride feel harsher and potentially reducing traction on bumpy trails.

Adjustment Tip: In hot conditions, consider reducing the shock pressure slightly to maintain a balance that offers comfort without compromising control. Monitoring the pressure throughout the ride is also beneficial, as temperatures can fluctuate significantly. For every 20°C increase around 5 PSI should be removed.

3. Humidity

Humidity itself doesn’t directly change shock pressure, but it can influence the performance of seals and lubricants within the shock. High humidity can lead to increased friction and resistance, which might affect how smoothly your suspension operates.

Adjustment Tip: Ensure that your shocks are well-maintained and lubricated appropriately for the conditions. Regular maintenance checks can help prevent humidity-related issues from impacting your ride. Have a look at this blog post to see how to adapt your MTB settings for wet terrain.

4. Altitude

While not strictly a weather condition, changes in altitude can also affect MTB shock pressure. Higher altitudes typically mean lower atmospheric pressure, which can lead to an increase in the internal pressure of your shocks.

Adjustment Tip: When riding at different altitudes, it’s essential to adjust your shock pressure accordingly. A portable shock pump can be invaluable for making on-the-fly adjustments.

Practical Tips for Managing MTB Shock Pressure in Various Conditions

  1. Regular Checks: Make it a habit to check your MTB shock pressure before every ride, especially when there’s a significant change in weather conditions.
  2. Learn how to set up air pressure with the SAG method.
  3. Use a Quality Shock Pump: Investing in a reliable shock pump with a precise gauge can make a big difference in maintaining the right pressure.
  4. Know Your Baseline: Understand the recommended shock pressure for your weight and riding style, and use this as a baseline to make adjustments based on weather conditions.
  5. Monitor Performance: Pay attention to how your bike feels on the trail. If it feels too stiff or too soft, it might be time to adjust the shock pressure.
  6. Stay Informed: Keep an eye on weather forecasts and be prepared to make adjustments as needed. Extreme weather conditions often require more frequent pressure checks and adjustments.


Understanding and managing MTB shock pressure is vital for an optimal mountain biking experience. Weather conditions like temperature, humidity, and altitude changes can all influence your shock pressure and, consequently, your ride. By regularly checking and adjusting your shock pressure, you can ensure that your bike performs well regardless of the weather, providing a smoother, more controlled, and enjoyable ride. Happy trails!
