Air suspension to pressure to weight ratio

Hi, i have a manitou minute fork and a manitou spv rear suspension. My question is, Is there such thing as the psi to weight ratio? and if there is, where can i find it??

Have you tired typing "manitou spv manual" into google and seeing what you find? Or more specifically the actual model name/number of your shock followed my 'manual' and seeing what you find? I'll bet you'll find your answer.

Better than that, Manitou is one of the best companies for easily making available archive documentation for their products. Andrew, you will probably find your owners manuals here (as well as service manuals should you ever want/need them):

Every model has its own ratio, so no there isn't a general rule. As mentioned above, look up manufacturer documents or contact them.

The values given are generally just a recommendation, though. In the end, it really comes down to rider preference.

I like to run my pressures a bit higher than the recommended level for my weight. I just prefer the way the ride feels when it's that little bit stiffer. I don't like an overly squishy ride.

It is better go set the air suspension by sag. That is % of travel used when you sit on the bicycle. Of course up to you.. there are limits to psi you can put in/take out though

^^ But if the person has no clue, it's best for them to look up the factory-recommended settings first so they don't screw anything up - - then adjust sag to taste (and the Manitou manuals have recomended sag percentages published as well).
