    Lefty Air Loss - normal?

    I bought a Caffeine 29er back in the fall and have maybe 20 hours on it and absolutely love it. It's been cold and snowing for the past several months so I haven't ridden it, but going to Sedona this weekend to ride. Went and looked at my lefty and it is completely empty of air. I don't notice any oil leaks (after search this seems to be more common).

    Is it normal to have your shock lose all its pressure after sitting for a couple of months unused? I have not had this problem w/ my Rock Shok or Fox - maybe lose some pressure but not empty.

    If not normal, any solutions?

    Appreciate any help,

    Brian

    The most common causes are a loose or dirty air valve (make sure you keep a cap on it, dirt will make them leak in a jiffy) or seals that are flattened on the air piston. Either way, not an expensive issue. Take it to your dealer, assuming they can help you in house. If they send it out for this, they ned to be shot, then closed as a Cannondale dealer.

    Thanks for the input - i do have a cap on it, but haven't checked to see if the valve is loose. I'll give that a shot, pump it up and ride it and see what happens.

    Any idea if it is dangerious to ride if a flattened air piston?

    Is replacing an air piston a complex fix that a dealer needs to do or is it something that I could do myself (given average mechanical skills)?

    It's not dangerous, just very annoying

    Sure, you can do it, you'll need a Catle tool to remove the cartridge, then remove the bottom cap, take a dowel and push the piston out. Replace O rings, reverse process.

    It's one of those days where I'm stuck in an office, in front of a computer but in no mood to do some actual work...

    Any online directions on how to do this or a breakout of the shock?

    Also, where would I get the replacement O rings and Catle tool?

    Unfortunately the closest dealer is 75 miles from here so it is unlikely that I'll get it to a Cdale shop.

    Thanks,
    Brian
