Frame size: M
Rider weight: ~78kg
Rider w gear: no idea
Shock: DHX Air
Shock settings: 165psi main chamber, 150psi boost valve, half circle bottom out from fully open position, medium rebound.

i'm not sure i like the 150psi in the boost valve, feels kinda harsh to me. still messing with it.

Rider height: 5' 11"
Frame size: L
Rider weight: 165-170 lbs
With gear: 175-180 lbs
Shock: DHX Air
Settings: 160 main(gives 1/2" sag), 140 boost, half circle from full open, 9 clicks rebound(half way). I do find I've had to decrease rebound(4 clicks) in the cold weather of late, making it 6 clicks from full open. The same goes for my Z1 up front.

Rider height: 5' 7"
Frame size: M
Rider weight: 145lbs
With gear: 150lbs max
Shock: Cane Creek Double Barrel.
Settings: 350 lbs Ti spring= 25% Sag, no clicks of low speed compression, 8 clicks low speed rebound, 1 turn of high speed compression, 1/2 turn high speed rebound.

shock as 24 clicks on low speed settings, 2 full turns on high speed settings.

Result = Very active suspension, yet still compliant when pedaling. Bike is glued to the ground, and I rarely feel a bottom out, although I know it's happening.

Rider height:6' 3"
Frame size:Large
Rider weight:185 lbs
Rider w gear: 190 lbs
Shock:MANITOU EVOLVER :150 psi main - 70 psi piggy- reb. 13 from open- hsc, lsc fully open- piggy volume #3
with this settings I use almost whole travel in hard trail raiding (no drops)

MANITOU SWINGER COIL 4WAY 450lbs x 2.25 coil set - 50 psi piggy - reb. 12 from open -
far more sensible than evolver on small bumps.
I'll post complete review with the two shocks when i'll get more feedback in different situations.
Cheers. Filippo

I've tweaked things for more "freeride" situations. 175psi main chamber, 130psi in the piggy, pos. 3 on the bottom out, one full turn of low-speed compression, 3 clicks high speed, same rebound.

I have a question about the DHX Air boost valve. is it dangerous to run the minimum of 125 PSI and some extra pressure should be added just in case or fox has some error margin?

I know that those shock pumps are inaccurate and I'm afraid to screw something..

I asked fox tech support about this and they told me that 125 psi is the minimum and that I should put 130-135 PSI because some air is lost while removing the pump. does it make sense?

yeah. the chamber that you're filling is extremely small, so some pressure is going to bleed off no matter how quick you are with removing the pump.

Really? I thought they were designed to close off the intake before breaking the seal, so the air you hear escaping is coming from the hose not the shock.

I've been doing it all wrong?

we it depends on the quality of the shock, they are designed to stop leaks from the vessel you are pressurising, but because the volume of the chamber is so small (as 2cranky said) any release of air at all will make a substantial difference.

Personally i would pump up 5psi more than min, just to be safe.

I have ran mine @ 125psi with no problems at all; my last bike had a 06 DHX air (200mm x 50mm) on it and I ran that at 100psi for over a year with no probs. I am sure the early DHX's had a 100psi minimum on the sticker whereas the 08 has 125. :thumbsup:
