To determine the ideal rebound setting for your shock, it's important to understand what exactly you're adjusting.
Every shock relies on damping to counteract the negative rebound effects that occur when the spring compresses. Without damping, the shock would feel excessively bouncy, akin to a pogo stick. To address this, we use an oil-filled damper to slow down the shock's return to its fully extended length after compression. By restricting the flow of oil in the damper, we control the rate at which the shock extends, increasing the force needed to extend it after compression.
In models with Rebound Adjustment, you have the ability to modify the rebound rate of the shock. This adjustment alters how easily oil flows through the dampers, thereby affecting ride quality—either making it bouncier or less bouncy.
To illustrate, consider a basketball filled with air. When you bounce it on the ground, it rebounds relatively quickly, similar to shocks operating with more rebound (e.g., position "1"). Conversely, if you release some air from the basketball and bounce it with the same force, it rebounds more slowly, akin to shocks operating with more damping (e.g., position "6").
The rebound adjustment in the AIR-A and REVO-A models offers six positions. Position 1 provides more rebound for a bouncier ride, while position 6 offers less rebound and more damping, resulting in a less bouncy ride. Position 1 allows oil to flow more freely through the damper, while position 6 restricts oil flow more significantly.
What does this mean to you as the rider? You have the ability to fine-tune your ride to changing road conditions, or riding configurations (one-up, two-up, etc.). The rebound adjustment is purely rider preference, meaning one rider may prefer position 6, whereas another rider may prefer position 1. It's up to you as the rider to experiment and determine which position you like best!
