What is most important when adjusting my front forks, sag or manufactures recommended pressures?
I ask because Rock Shox recommends 180 psi for my weight for their revelations, but for me to get 20% sag i can only run with 100psi.
I can understand a small differance to take into account of different frame sizes & geomentry but this is almost half the recom pressure.
In case it matters it is on a cube ams 125

Thanks

    I got the same issue on my Revelation 426s.
    My recommended psi is 140 but I run at about 100 to get any measurable sag. I change the negative pressure depending on the terrain but usually run about 110psi. I like it soft.
    IMO it depends on if you run the traditional head down, arse up position with more weight over the front axle compared with the recent trend of a relaxed riding postion, more upright with comparitively more weight over the rear axle. If your blowing through the full travel a lot just increase the + pressure and/or reduce the - presssure.
    Could be wrong, often am.
    Either way with these forks you twiddle about withe the pressures until it's right for you.
    Here endeth the first lesson.

    Forget the reccomended pressure. Just set the sag to 20%.

    Are you using the same pressue in both + and - chambers? You do know how to setup negative air? If not it should be within a maximum of +10/-10psi of the positve air (depends on personal preference).

    yes, same in both + & -

    Just checking.

    If it was wrong it may have exlained the pressure difference between the two forks.

    So there's no problem there then. I would just go with whatever is needed to give you the desired sag.
