If you're thinking about trying to use a normal pump on your air shock like I was...don't be. Technically they do have the same interface, and I know that can be tempting. I thought to myself, "why buy a 'shock pump' when I could just use a pump I already have?" Don't make the same mistake I did. You know that little "psst" that escapes when you take your pump off the tire valve? It's enough to let every air molecule out of your fork. Your shocks need wayy more precision than your tires need, and that precision is just what "shock pumps" are made for. You screw it on, add or remove psi as needed, and take it off without any air leaking out. It's the only shock pump I've used, but I don't see what more you could want from one.
