Checking and Adjusting the Rebound Damping
Properly maintaining your Suntour fork includes regularly checking and adjusting the rebound damping. Rebound damping refers to the fork’s ability to return to its original position after compression.
1. Setting Your Sag
Before adjusting the rebound damping, it’s important to set your sag correctly. To do this, follow these steps:
- Unmount any accessories, such as fenders or racks, that may affect the sag measurement.
- Position yourself on the bike in your normal riding position, wearing all necessary riding gear.
- Have a friend or use a sag measuring tool to measure the sag. The sag should generally be set between 15-30% of the fork’s travel, with 25% being a common starting point.
- If necessary, adjust the air pressure in the fork using a shock pump to achieve the desired sag.
2. Checking Rebound Damping
Once you have set your sag, it’s time to check the rebound damping. Follow these steps:
- Start by pushing the fork down and allowing it to rebound naturally.
- Observe how the fork rebounds. It should return to its original position smoothly and without excessive bouncing.
- If the fork rebounds too quickly and bounces back, the rebound damping needs to be increased.
- If the fork rebounds too slowly and doesn’t return to its original position quickly enough, the rebound damping needs to be decreased.
3. Adjusting Rebound Damping
Adjusting the rebound damping is done using the rebound adjustment knob located on the bottom of the fork leg. Follow these steps:
- Locate the rebound adjustment knob on the bottom of the fork leg.
- To increase rebound damping, turn the knob clockwise. To decrease rebound damping, turn the knob counterclockwise.
- Make small adjustments to the rebound damping and test the fork’s rebound after each adjustment. Continue until you find the optimal rebound damping for your riding style and preferences.
It’s important to note that rebound damping is subjective and may vary depending on rider weight, riding style, and trail conditions. Experiment with different settings until you find the rebound damping that provides the best performance and control.
