Of course, I may be wrong.
Not wrong - thank you.
As I tried to explain, the 'Zocchi manual shows two different lines - one shows weight measured in POUNDS (weight on the bars - NOT PSI), vs. preload air pressure (measured in PSI - pounds per square inch).
Again, you add 0 - 15 PSI to achieve a sag of 20 - 25% of total available travel. The MX COMP series that started all this, only has one air valve. Maybe someone would like to tell me why the manual shows 0-15 PSI of preload, and 30 - 65 pounds positive air? It can't be both.....there's only one air valve on the Comp.
Again, adding 0 - 15 PSI gives you 30 - 65 pounds of positive air.
