Twin Shock SLR Calculator with Single Rate Spring Calculator
Enter values from your rear geometry in the light blue fields.

If you inadvertently clear any other fields, just close the page and reselect the link, the calculator
will reload with the default values.

Below is the method from the original manual.
My recommendation: Go to the SLR calculator and get out the tape measure if you do not see your bike listed.
Email or call with the measurements if you are uncertain or have any problems.
