RockShox HP 2-Stage Shock & Tire PumpWhat you're looking at is the ultimate behemoth of shock/tire pump combos. If you're going on a backcountry trip where bringing two pumps is a requirement, this is the all-in-one you've been looking for. As a shock pump it's rated to 300psi. Extended to use as a tire pump and you'll hit your desired pressure no problem. We got it up to 40psi without breaking a sweat.
If you have a fork that is worth anything, it has adjustments that require a pump and like anything with air, they can leak or pressure changes with the temperature. This pump eliminates the need to carry a shock and a tire pump. Let's face it....we spend enough money to lighten our bikes as it is.
I have noticed that every time I pump up my fork and then detatch the hose, I lose about 10psi. I quickly reattach the hose and the dial is 10psi lower than when I pumped it up. It's annoying but I just overfill it the first time now. I don't know if the dial is incorrect or if it's something with my fork. I also tried to inflate my tires with presta valves (with the valve core still installed) and a schrader converter screwed on with no luck. I don't think it's even set up for that so I don't knock it for it, but I just thought I'd give it a shot. Folds small and the dial is easy to read (if it's actually correct).
