    What are you using to pump your air shock?

    I recently installed a RockShox solo air fork which has a shrader valve for air inlet/outlet and was wondering if it is necessary to buy a shock-specific air pump with built-in dial gauge.

    Could I just use a small air compressor or are these shocks that finicky that a bike-specific pump is necessary? I haven't even attempted to use the air compressor but also wouldn't mind saving $40 if I can.

    Thanks.

    I'd buy a shock pump. The volumes of air are small, and would you be able to get the precise pressure you wanted using a compressor?

    Here's one on eBay now for only $24:

    Yeah that's the advice people seem to be giving outside of this forum after a google search -- buy a shock pump.

    Went to a LBS today and other than charging $6 for a star nut he wanted over $50 for the shock pump (Cannondale brand) which is where I came up with the idea to use my air compressor.

    Did you buy the fork NIB? When I bought my RS Reba it came with a pump. Yes, I recommend a shock/fork pump.

    Yes, I bought the fork NIB. It is a RockShox Recon Gold and did not come with a pump.

    I'm digging the the pumps with an attached hose. Probably make it easier to maneuver the pump and for better positioning when in place.

    I have a RavX and a marzocchi . I like the RavX because it has a little release on the shraeder fitting so you don't lose as much air when you unscrew it. I think it was about 30 bucks. The marzocchi works better for low pressure forks, IMO.

    I have a topeak dxg shock pump. It's small and convenient to put in my camelbak in case I need to tune mid-ride, which is pretty rare unless I'm on a new trail.

    FWIW, my new Fox fork didn't come with a shock pump.

    Sette Air 2 ST-35 Universal Shock Pump at Price Point

    This is what I use. Not bad for a $25 pump.

    An air compressor will blow your fork/shock up. Even if you could use an air compressor, you would lose all the air when you check the pressure with a gauge. You have to use shock/fork pump. You never lose air from the fork/shock when you unscrew the pump. The air you hear is the air coming out of the hose of the pump. Don't tighten the pump on to hard.

    +1 on what he said. I just got the X-Fusion Slide 29er and needed a pump. Got mine off Amazon for under $30. Easy to use and quick inflation plus has a built-in valve in the connector so you don't lose air pressure when you unscrew it.

    Thanks for the help everyone!

    I ended up buying a new RockShox pump for $25 shipped off ebay.

    You don't lose air with any pump when you unscrew it.

    Gonna have to disagree with you there Shawn...I had a pump that would definitely bleed off as it was unscrewed. It was a real PITA and was resolved by getting a Topeak pump with the double thread (one to engage the schrader and one to open the valve).
    whatever...

    Then there is something wrong with your valve on your fork/shock. The valve closes from the higher pressure in the fork/shock as soon as you unscrew the pump. The air you hear coming out is from the air in the hose of the pump. You get a lower pressure reading when you screw the pump back on because that same hose fills with air.

    Yup, the bleed is from the air in the hose and not the shock.

    I got a schwinn pump that my LBS sold me for 30$ used because they didn't have any shock pumps in stock. Its a very nice pump, everything is solid metal and I would feel comfortable dropping it off the top of a building!

    Why would an air ompressor blow up your fork/shock? The issuse I have with the air compressor is that mine only goes up to 100 psi. And I don't have any accurate way to change the PSI with such a small volume. If I just wanted 100 PSI everytime then the air compressor would work fine.

    Whatever the pressure in the tank is (or the setting of the pressure regulator on the hose) that is the max pressure you are going to put in the shock. As long as that is not too much pressure, you will not damage the shock.

    You never lose air from the fork/shock when you unscrew the pump. The air you hear is the air coming out of the hose of the pump. Don't tighten the pump on to hard.
    This is correct^^^^
    15mm is a second-best solution to a problem that was already solved.

    It's the quick shot of high pressure from a large tank into a small shock air chamber that blows the shock or fork. And, if the compressor is on, that makes it worse.
