If you’re an avid mountain biker, you know how important it is to have a properly functioning suspension fork. The SR Suntour XCT is a popular choice among riders for its durability and performance. However, like any suspension fork, the XCT requires regular maintenance and adjustments to ensure optimal performance on the trails.
Adjusting the SR Suntour XCT forks is a relatively simple process that can greatly improve your ride quality. One of the key adjustments you can make is controlling the fork’s rebound. Rebound refers to how quickly the fork extends back to its original position after compressing. Having too much rebound can make the fork feel harsh and unpredictable, while too little rebound can result in a “pogo” effect, where the fork bounces uncontrollably. By adjusting the rebound, you can find the perfect balance for your riding style and terrain.
Another important adjustment to make is the fork’s air pressure. The SR Suntour XCT features an air spring, which allows you to adjust the fork’s stiffness based on your weight and riding preferences. By increasing the air pressure, the fork becomes stiffer, making it more suitable for heavier riders or aggressive riding. Conversely, decreasing the air pressure makes the fork softer, ideal for lighter riders or smoother trails. It’s important to find the right balance of air pressure to maximize performance and comfort.
In addition to rebound and air pressure, you may also need to adjust the fork’s preload. Preload refers to the initial compression of the fork when you sit on the bike. By adjusting the preload, you can set the sag, which is the amount the fork compresses under your weight. Finding the right sag is important for maintaining traction and control on the trails. A good starting point is to set the sag at around 25-30% of the fork’s total travel, but you can fine-tune it based on your personal preference.
By following these simple adjustments, you can ensure that your SR Suntour XCT forks are dialed in for your riding style and terrain. Remember to take your time and experiment with different settings to find the perfect balance of performance and comfort. Happy riding!

Step-by-Step Guide to Adjusting Compression and Rebound
Adjusting the compression and rebound on your SR Suntour XCT forks can greatly improve their performance and make your riding experience more enjoyable. Here is a step-by-step guide to help you make these adjustments:
Step 1: Start by locating the compression and rebound adjustment knobs on your forks. The compression knob is usually located on the top of the right fork leg, while the rebound knob is typically located at the bottom of the same leg.
Step 2: To adjust the compression, turn the knob clockwise to increase compression damping or counterclockwise to decrease it. Compression damping controls the fork’s ability to absorb impacts and influences how it responds to big hits and fast, successive bumps.
Step 3: To adjust the rebound, turn the knob clockwise to increase rebound damping or counterclockwise to decrease it. Rebound damping controls the speed at which the fork extends after being compressed and affects how quickly the fork returns to its original position. Adjusting the rebound can help prevent the fork from feeling too bouncy or too sluggish.
Step 4: Start with the compression and rebound settings in the middle position (usually indicated by a “suggested starting point” label). This will give you a good baseline to work with, and you can fine-tune the settings based on your riding style and trail conditions.
Step 5: Go for a test ride and pay attention to how the forks feel on different terrains and when encountering various obstacles. If the fork feels too harsh and doesn’t absorb impacts well, try reducing the compression damping. Conversely, if it feels too soft and bottoms out easily, increase the compression damping.
Step 6: Similarly, if the fork feels too bouncy and doesn’t return to its original position quickly enough, increase the rebound damping. On the other hand, if it feels too sluggish and doesn’t extend fully, decrease the rebound damping.
Step 7: Continue making small adjustments to the compression and rebound settings until you find the optimal setup that suits your riding style and trail conditions. Remember to make only one adjustment at a time and test the forks after each adjustment to assess the changes.
Step 8: Once you’re satisfied with the settings, make sure to lock the adjustment knobs to prevent them from loosening during your rides. This can usually be done by pushing down and turning the knobs in a clockwise direction.
By following this step-by-step guide and fine-tuning the compression and rebound adjustments on your SR Suntour XCT forks, you can maximize their performance and enjoy a smoother and more controlled ride.
