    Shock N Roll Shock pump

    Hey fellas,

    Im new to the mtn bike world. I have a issue that i need some help with. My fork and shock are feeling a little soft and i seem to have a little to much sag right now, so i got a Shock N roll shock and tire pump, i put it on, switch it to shock mode, pump it, but air is comming out of the back of the pump. What the heck is going on???

    Not specific to this pump but I've accidentally pushed the air release when I try to push air in (rookie mistake).

    If that's not the case, maybe you have a leaky seal. Return it, get a lezyne and be done with pump problems

    From the info on Topeak's website, I assume the Shock N Roll is a two chamber pump. The large volume/low pressure chamber and a low volume/high pressure chamber are used together to fill tires. When filling shocks, the pressure from the high volume chamber is dumped ("out the back of the pump") and only the high pressure chamber is used.

    Sounds like your pump is fine. Where you able to to fill your shock and fork?

    My Joeblow Ace floor pump works the same way only it has 3 chambers.
