Adjusting For Transitions - Fine-Tuning Your Shocks Photo Gallery
This is a graph generated by a shock dyno that shows a relatively normal shock. The rebound (the bottom half of the graph) is a higher rate than the compression. Relate the pounds of resistance reading on the left side with the speed which is along the bottom of the graph in inches per second. This shock has around 75-100 ppi of resistance in compression and 200 ppi of resistance in rebound at 3.0 inches per second of shaft speed.
