so yer like snakes on planes...

this is probably a silly question but, ill be taking my bike to andorra next week, do i need to let some air out of my rear DHX air shock or will it be ok?

Yeah, there was a topic on this a long while back, you don't need to remove any air.

As eddy said, bikes are perfectly safe on planes aslong as they are packaged properly.

Have fun in Andorra!

Not related to the topic as such,
But i dont get why you would have to let the air out of your shock ?  

And what interdh5 said, Why the presure out the tyres also ? 

its all nonsense, the maximum change in pressure would be -1bar below atmospheric and your shocks and tyres will take way over that, when you bottom out your shock is at a psi well over the pressure diferential in a cargo hold.

No it won't - as Screech rightly stated. All aircraft holds are pressurised to exactly the same pressure as the passenger cabin which is equivalent to 8,000 - 10,000 feet at cruising altitude. If you're off to the mountains you may well be going to take lifts to that sort of Altitude and you don't change the shock and tyre pressure every time you go up or down a lift do you. Even if the Aircraft accidentally depressurised the pressure change would be maybe 10 psi and increasing the relative pressure in your tyres or shock by 10 psi is hardly likely to be a problem. These rules are normally invented by people who don't understand physics and once they exist they get perpetuated.

I'd put money on that being more to do with the handling than air pressure

have you never heard of the guys changing tyre pressures on the plane tyres mid flight

well 150psi is quite high anyway but its more likely the shock was damaged physically by its handling than by the pressure, think when the shock is bottomed out its lost sooooo much volume the pressure hits a crazy spike.
