    Just got a CCDB air, brand new, it seems to leak over time. 14 days ago i inflated to 175, today it is 125. Normal or do I have a problem?

    *shock has just been sitting

    I wonder if using it a bit would move around lubrication on the air spring seals and it would seal better?

    It's worth a shot...

    Also, it seems like a lot of pumps will read lower than whats actually in the shock since they have to pressurize before they give a reading. 50 pounds is a pretty big jump though.

    Could the fluxuating temperatures have something to do with it too?

    dude, when you put the pump on the shock, air comes out of the shock and fills up the hose giving you a different reading than when you last pumped it :thumb:

    now 50 psi is quite a bit but unless you have a high quality pump, my guess is that shock is perfectly fine.Beside, is a 175 psi fair amount of pressure and even if you did have even the smallest of the leaks, it would go much lower than 125.

    Mine has not leaked at all. But I am only running 120 psi to begin with and it never sits for long. This shock is perfect on the Yeti 66.

    My experiance with air shocks is the pump (rock shox) will read 10psi lower than i pumped it up at the first time. also after a rebuild the shock will leak until its first use due to excess amounts of lube under the seals. untill that stuff is pushed around a little I think its possible for air to leak out. this could be the same for new shocks but I never noticed that.

    Cool, I will reset it to 175 and ride it a bit and see what happens, its not necessarily a huge problem, but if its not supposed to I would rather send it back brand new than "jra"

    the qa on cane creed db airs seems to be rather not solid ^^ a friend of mine got two.
    one for his v10 and another for his enduro.
    both had bushing play (even the first replacements sent to him by cc were not ay better) and the 2nd one looses all air within a day ^^

    so imho if in doubt call them and send it back.

    Mine was leaking air via the schraeder valve after the first ride. I just tightened it up a bit with a valve tool and it's been fine since.

    are you a ryan dungey fan? that might be the problem, the instant he started bouncing on that thing at A3 i felt all the air in my various air sprung suspensions suddenly fail

    pump it up and stick it in some water, same as looking for a puncture. Not a huge leak rate but I reckon you'll see something

    Feels like it has to go back, took it down from the wall to bounce on it, and its got negative at the top stroke. Left upside down overnight and nothin changed. Guess I'm unlucky

    You wouldn't notice such a big difference in the pressure like some people say. On a piggyback which has a very small air chamber and a big percentage of the air goes into the pump to get a reading, yes. On a relatively high volume air spring chamber, no, maybe 5 psi at most.
