Below images represent some key features of the Software.
The program screenshots below demonstrate what changes in the chassis including dramatic changes in center of gravity, trail, wheelbase, pivot, etc.; just by changing the the rear sprocket gearing from a 45 tooth to a 42. SuspAct software will display change differences in RED when viewing multiple bikes.
The force graph below shows Wheel Forces vs. Wheel Stroke effects on two identical bikes with different shock and fork spring rates
The program image below shows an adjustment from a 3mm shock height to a 5mm. Notice the rake, trail, wheelbase, pivot height, swign angle and center of gravity are completely different and so will the handling aspects of your bike. SuspAct will allow you to make educated changes to maintain your bike's optimized geometry.
