Introduction by Francis Cebedo
Brian and I both have this pump and have been spending quality time with it. In this day and age, suspension setup is everything. Bikes are supposed to be ridden with the right amount of sag for a given rider. And this can be the difference between an all-mountain bike riding well or not.
Brian does an excellent job describing this tool (as he always does). But I’ll add to his assessment with a key strength and weakness. The key strength is it’s deadly accurate On the old gauges, it’s hard to tell if it’s 62 psi or 64 psi. On this guage, you will know that it’s exactly 62.5 psi this time and every time you set up.
And a weakness is obvious but I’ll say it anyway. It needs to be turned on every time. Where the old pumps have a needle gauge and they’re always working, This digital pump needs to be turned on every single time you use it.
If you care about suspension setup and want repeatable psi readings, this is a good tool.
Review by Brian Mullin
Have you ever hooked up a shock pump, and then looked down to check the pressure reading and found it difficult to ascertain the exact value? Not only can it be tough to decipher the actual number, but the scale is so jammed up on the gauge, that precise measurements are almost impossible. Standing there several feet over the small gauge exacerbates the issue, as does eye strain and poor vision (like getting older). Enter the perfect solution, the FOX HP Digital Pump.
This is an easy to use high pressure pump, which has a simple readable digital gauge, with a large numerical LCD readout. The gauge can show in four different pressure scales, and has many excellent features; the foremost is the superb bleed button that allows precise air pressure adjustments. I have thoroughly enjoyed using this device over the last several months, and it has been incredibly useful and functional for making suspension pressure changes in my vast array of test shocks and forks.
The FOX Digital High-Pressure Pump is constructed with an alloy body, and has an alloy pump handle, a large plastic digital gauge, and a swivel mounted rubber hose with a Schrader valve connector and an air bleed button. The LCD digital gauge outputs in four pressure scales: psi (pounds per square inch), bar (100 kPa- from Greek baros meaning weight), kg/cm² (kilogram-force per square centimeter), and kPa (kilopascals), the latter is the SI (International System of Units). It reads up to 300psi in small increments and retails for $70.
Features and Impressions
The extra long Schrader connector makes it easier to connect and thread onto forks and shocks, which is especially nice on finicky valves and those that have deep recesses. It always drive me batty trying to attach up a simple pump to a Schrader valve, and more than a few cuss words have been tossed out of my mouth using the standard variety connector. The hose swivel makes is handy to get the proper angle for reading the gauge and attaching the connector, and it also extends the life of the hose since it’s not bent at odd angles, and therefore the rubber isn’t repeatedly pinched and crimped. After three months of use, the swivel has been bombproof and hasn’t leaked or shown any signs of wear. The swivel rotates 270° around its connection point, and stops up against the gauge housing at its maximum rotation. The hose is flexible enough to squiggle around things, yet its thick enough for durability and robustness.
Adding air can take a longer time at higher pressures as the pumps chamber is narrow so you can’t produce a lot of volume for each stroke. On the other hand, this allows delicate adjustments of the pressure, so small and precise additions can be done. The stroke was nice and smooth while pumping the handle, and I didn’t have any issue bringing my rear shock up to 150psi.
