> This section covers setting Maximum Available Travel, Bottoming Points, and Air-Time Adjusted Average Travel. Changes are automatically saved!
> Set Maximum Available Travel Maximum travel is the basis of many of the automatic measurements. It also controls graph scaling on many graphical screens. The default value for Maximum Travel (for up to 6 different vehicle types) can be set in Preferences. Maximum Available Travel can be adjusted by using the control on the “Bottoming” screen. This value is saved automatically whenever the file is closed.
Enter the maximum available travel for the front or rear. Check your vehicles user manual for assistance finding this value.
> Bottoming Counter How many times the suspension bottoms as well as how hard it bottoms is critical information. We have invented something called a “Soft Bottom” and a “Hard Bottom”. The idea is that Soft Bottoms can be OK but Hard Bottoms are generally not good as this is close to metal-to-metal.
- How to set the Bottoming Points Hard and soft bottoms are setup as a percentage of Maximum Available Travel. They are input in Preferences under Vehicle Type Setup. They can also be adjusted on the “Bottoming” screen.
- Bottoming Counter Sensitivity To help detect bottoming points with a high degree of accuracy, ShockClock Software allows you to adjust the Bottoming Counter Sensitivity. Dirt bike waveforms have sharper peaks than road race waveforms so the setting works better at 6. Road Race works well at settings of 10 or higher. This is set in Preferences. A lower number selects more peaks while a higher number selects less.
This can be setup as an automatic default for a particular Vehicle Type in Preferences.
> Average Travel Average Travel is a number that can be compared between front and rear as well as between different settings and tracks. Pay attention to this to create “sweet zone” numbers for different riders and tracks. > Air-Time Adjusted Average Travel (Dirt) Off road vehicle tires leave the ground frequently. While the vehicle is in the air the suspension is fully extended. On a “Supercross” style track with lots of jumps this airtime can skew the average travel measurement to a lower number.
ShockClock Software provides a way to subtract the “Air-Time” from the average travel calculation. By entering a value into the Air-Time Adjustment, ShockClock can provide Air-Time Adjusted Average Travel. 5 mm should work well.
In the example, the Lower Limit value has been set to 4 mm. All data less that 4 mm will be disregarded.
In this example Average Travel goes from 72 mm to an Air-Time Adjusted Average of 83 mm.
