One common question that arises among riders using air forks is whether it is okay to bottom out the fork during their rides. Bottoming out refers to when the suspension compresses fully and reaches its maximum travel, causing a harsh impact between the fork and the frame. It is an important consideration for riders to understand the impact of bottoming out and whether it is detrimental to the performance and longevity of their air fork.
Bottoming out can occur in various situations, such as aggressive jumps, drops, or harsh landings. It can also happen when riders hit unexpected rough terrain or obstacles on the trail. While bottoming out occasionally is generally accepted and won’t cause immediate damage to the fork, excessive or repetitive bottoming out can lead to potential issues.
One concern with bottoming out is increased stress on the fork’s internals and seals. The force of the impact can potentially damage parts and cause oil leaks. Additionally, bottoming out frequently may reduce the fork’s overall performance and compromise its ability to absorb impacts effectively.
However, it’s important to note that air forks are designed to handle a certain degree of bottoming out. Manufacturers recommend setting the air pressure and adjusting the suspension settings to prevent excessive bottoming out. Proper setup, regular maintenance, and periodic inspections of the fork can help riders avoid any potential issues and ensure optimal performance.
In summary, while occasional bottoming out is generally acceptable and won’t cause immediate harm to an air fork, excessive or repetitive bottoming out can potentially lead to damage and reduced performance. It is crucial for riders to follow the manufacturer’s recommendations, properly set up their suspension, and regularly maintain their forks to prevent any potential problems.
Can bottoming out an air fork damage it?
Bottoming out an air fork, which is when the fork compresses fully and the travel limit is reached, can potentially damage it. While modern air forks are designed to handle a certain degree of bottoming out, repeatedly pushing them to their limits can lead to issues.
When an air fork bottoms out, the internal components are subjected to significant forces that can cause wear and tear over time. This can lead to decreased performance and potential damage to the fork. Additionally, bottoming out can also increase the risk of damaging other components of the bike, such as the frame or handlebars.
To prevent damage to an air fork, it is important to set up the suspension properly. This includes adjusting the air pressure and adding or removing volume spacers to change the progressivity of the fork. It is also crucial to regularly service the fork and maintain the seals and internals properly.
Signs of potential damage:
- Loss of performance or a harsh feeling when the fork compresses
- Leaking oil or air from the fork
- Noise or creaking sounds during compression
- Inconsistent or unpredictable suspension behavior
Conclusion
While it is generally not recommended to bottom out an air fork, occasional bottoming out may not cause immediate damage. However, repeated or excessive bottoming out can lead to decreased performance and potential long-term damage. Proper setup, maintenance, and gradual adjustments are key to ensuring the longevity and optimal performance of an air fork.
What happens when an air fork bottoms out?
An air fork is a component commonly found in mountain bikes and other off-road bicycles. It uses compressed air to support the rider’s weight and provide suspension for a smoother ride on rough terrain. When an air fork bottoms out, it means that it compresses fully and reaches the limit of its travel.
Bottoming out can have several effects on the performance and safety of the fork. Here are some possible consequences:
Loss of suspension
When an air fork bottoms out, it loses its ability to absorb impacts and provide suspension. This can result in a harsh and uncomfortable ride, as the fork is unable to effectively absorb bumps and vibrations. It can also make the bike more prone to damage, as the forces from impacts are transferred directly to the frame and components.
Decreased control and handling
When the fork bottoms out, it can affect the bike’s control and handling. The lack of suspension can make the front end of the bike feel rigid and less responsive to rider inputs. This reduced control can be particularly problematic on technical trails or when navigating obstacles, as it increases the risk of losing traction or being thrown off balance.
Damage to the fork
Bottoming out can put excessive stress on the fork, its internal components, and the frame. The sudden impact forces can lead to the deformation or damage of critical parts, such as the seals, stanchions, or even the frame itself. This can compromise the overall integrity of the fork and potentially lead to expensive repairs or the need for a replacement.
To prevent the fork from bottoming out, it is important to properly set the air pressure and tune the suspension according to the rider’s weight, riding style, and the type of terrain being ridden. Regular maintenance and inspections of the fork are also recommended to ensure its optimal performance and safety.

How to prevent bottoming out in an air fork
Experiencing bottoming out in an air fork can be frustrating and potentially damaging to your bike. Fortunately, there are several steps you can take to prevent this from happening:
- Adjust the air pressure: The air pressure in the fork determines its stiffness and resistance to compression. Make sure you have set the air pressure to the recommended level for your weight and riding style. If you are consistently bottoming out, try increasing the air pressure slightly to provide more support.
- Check the sag: Sag is the amount that the fork compresses under your weight when you are on the bike. A proper sag setting ensures that your fork is using its full travel range and provides the optimal balance of support and plushness. If you are bottoming out, check your sag and adjust it accordingly.
- Rebound damping: Rebound damping controls how quickly the fork returns to its extended position after being compressed. If your rebound damping is set too high, the fork may not fully extend before the next compression, leading to bottoming out. Experiment with adjusting the rebound damping to find the optimal setting.
- Install volume spacers: Volume spacers are small plastic inserts that can be added to the air chamber of your fork. They reduce the volume available for air, making the fork more progressive and preventing it from bottoming out too easily. Consult your fork’s manual or a professional to determine the appropriate number of volume spacers to install.
- Consider a heavier spring: If you are consistently bottoming out despite adjusting the air pressure and other settings, you may need a heavier spring. Heavier springs provide more support and prevent excessive compression. Consult with a bike shop or suspension specialist to determine if a spring upgrade is necessary.
By following these steps and regularly maintaining your air fork, you can minimize the risk of bottoming out and enjoy a smoother and more controlled ride.
