    Rigid forks - could you post your front air pressure

    Could you share your ideal front tire pressure that works for you in most conditions. I am new to my steel rigid fork and I like to learn from the pros "you". Thanks in advance.

    I'd say just experiment; tire, rim, your weight and trail conditions play a lot in it.

    35-45, conditions dependant, sometimes as low as the low twenties in the snow. this on a dual duty rim with tires ranging from 2.1 - 2.4+, tubes.

    650b'sx2.3 tire @ 20-25 psi. It all depends on you're tire volume, rider weight, riding conditions, and all other kinds of crazy. Rule of thumb-how low can you go without pinch flatting or rolling a tire?

    A lot depends on rim size, tire width, tubed/tubeless, how tough the tire's sidewall is, the terrain and trail conditions you are riding on a given day, how big you are etc. I don't know if there is a standard you can use all the time.

    no quantifying

    You gotta factor in your weight, the rim, the tire you are running, with our without tubes, the day of the week, the elevation above sea level and the barometric pressure. Oh, and of course how smooth you are.

    After I am done with all that, my air pressure is just right to the squeeze... only takes a second, and requires no special equipment.

    Tubeless, Exiwolfs, 210lbs I like to run the pressaure at either 27 or 28lbs. Oh and I keep a light grip on the bars in rougher sections, not light enough to get away from me but definitely no death grip.

    I run an Exiwolf in the rear, Resolution Pro in the front - both 29 x 2.3 tubeless (Stans). I run low-to-mid 20's in the front, about 3 lbs more in the rear. Never pinch flatted in a year and around 1800 miles, but did slice one sidewall open (Resolution Pro, rear) on a sharp rock, and also did have a front "catastrophically deflate" when it released the Stans under a heavy side-load. I was playing the "How-low-can-I-go?" game and only had about 17 - 18 psi in there. Too low for a rocky, rooty trail with cambered descents! 23 psi or so and everything is fine. I weigh 185 and generally do the "push on the top of the tire" test for presssure. Only know the psi because when I do pump them that is about what the guage shows where the "pressure feels right" to my push test. Play around and find what works for you. You can go sub-20 psi with tubes very safely on a larger tire, but watch for pinches with tubes!

    Stan's Arch rims, usually run 36 psi. 200 lbs (210 riding) and dropping 38 for races usually.

    I thought I was the only higherish psi preferrer in the group. The other rigids in our group all seem to like the sub 30 ride.

    caveat this with the fact that I have three separate gauges and they all read different pressures. One is 10psi high the other 10 psi lower than the first and the other is around 2/3 the first.

    Pressure is something best left to ball park and then refine using one gauge as a baseline.

    that said 200lbs-ish and 29er rampage 28-29psi.

    Depends on the tire. I use anywhere from <10psi (Gazzaloddi 3.0) to >40psi (Maxxis Medusa 1.55).

    Stans 355 29er rim, Specialized fast Track Pro, 22 or 23lbs around home (MI) and about 5 more in rocky terrain. I'm 175lbs and would call myself an aggressive rider. If I go less than than and come down a little crooked when bunny hoping or jumping I feel the tire want to roll sideways-weird feeling.......

    I am new to this rigid deal and was wondering about pressures also. I weigh 156 on a good day, run a 2.5 tire up front, and recently ran 15psi with no problems.
