Crank Brothers' Power Pump Pro features a tough aluminum barrel, a switch to select high-volume (off-road tires) or high-pressure (road tires) inflation and a handy built-in gauge. It's also light and small so it's easy to carry in a pocket or pack. The Power Pump Pro fits Schrader and Presta valves, too.
Bought this to try it out as a "on the road" pump in case of flat tires - need 85 psi in a 700 x 28 Schraeder tube. This pump's twist-lock and poor seal cause massive pressure loss while you attach it, and the mechanism, on either "high volume" or "high pressure" setting simply can't do more than 30-35 psi, where you're going to start after you're done attaching this thing.
Will be returned.
Bottom LineNo, I would not recommend this to a friend
