    What ever is needed to give the sag I want.
    It is different in diferent forks,

    Rather pointless question just set your sag to what you want and adjust as needed so that you just bottom out once or twice.

    Across all the stuff I have owned, 15 - 175psi.

    So as Nick says, very dependant.

    75 psi - totally pointless question! You have to factor in your weight to get the sag you want. Usually 15-20%

    Enough to get the sag right with my fat ass on board.

    Dont forget to use the correct air. I get mine off ebay its Nitrogen 80% blend not cheap but I know I have the best.

    Rockshox vs Marzocchi vs Fox are going to have COMPLETELY different numbers here, even if everyone rode the same and had identical sag, due to the different systems. 80 on my Floats, 110 on my Rebas.

    I particularly enjoy the idiocy of so many people saying it's a pointless question, but still bothering to give their pressure anyway.

    Sag seems like a good enough starting point, but then so do the manufacturer's recommendations, based on your weight. I think, for my Fox forks they were psi=weight in lbs for the rear and around 60% of that for the front. But it's so easy to adjust and to get the best out of your suspension you need to understand how changing the pressure changes the feel anyway, which means experimenting. So, you might as well start with the recommended pressures, ride it, see how it handles (whether you are using all the travel etc) then see what effect changing the pressure has. Then you can ignore the recommendations and just go with what feels right.

    Cheers,

    The problem with "ignore the recommendations and just go with what feels right" is that many riders who are new to suspension aren't sure what "right" is, depending on what they've ridden before. A lot of riders who've only ridden hardtails or rigids tend to set their suspension up too hard, and therefore not getting the best use of it. Still others are setting it too soft, and not getting the best performance.
    There is some leeway from the "ideal" sag that can still work, and yes, it can depend on where you ride, but it's tricky to "feel" it unless you're experienced at tinkering with your setup.
    Of course, in order to become experienced and to learn the effects, you must fiddle, which is a bit of a catch-22 situation.

    Best bet is to set the correct sag, and don't mess about unless you've actually bottoming out constantly.

    This. Stiffened mine up last night (to 100psi :wink: ) as I'm bottoming out 4 or 5 (or more maybe) times per ride. Not that the Reba complains at all.

    You get the Green Alpine stuff over here. Can't notice the difference over the blue though (never tried the pink - ridiculous import duties on that one) :wink:

    so what you're saying is, "ignore the recommendations and just go with what feels right"? :mrgreen:
