Here's the thing about front suspension. Fork spring rates are based on load and are given in newton meters per millimeter. The higher the rate the stiffer the spring and unless it's progressively wound it's a constant rate. Progressive springs allow a smoother transition to full spring rate providing a smoother ride experience. Damping is set by the flow rate of oil thru the damper tube and on Rocket 3's have adjusters for compression and rebound rates. Suspension setup after break-in starts with setting static sag. Once that's good the shocks only need to be tweaked for compression and rebound rates. Setting the compression high means it takes a heckuva whallop to get full travel from the suspension, really low and the suspension can bottom out more easily over mild bumps. The rebound is the same thing in reverse, it determines how fast the shock spring can push the shock to full extension (sag limit). Get those wrong and you might be convinced you're rding a hardtail, or just as bad, it feels like a pogo stick. Just right and it feels planted, stable, and responsive.
