Test: With the Specialized Air Tool HP we have another pump for special use in the test field. HP stands for High Pressure - the Specialized pump is therefore aimed more at drivers who drive their tires with a lot of pressure. From a purely visual point of view, apart from its neon yellow color, the pump appears very sober and reduced.
The almost uncomfortably low overall height is striking right from the start. Our tester, who is almost 1,90 m tall, had to bend down when pumping - not particularly comfortable in the long run. Keyword comfort: The handle is made entirely of hard plastic, but at least ergonomically shaped - nevertheless: a little more comfort would have been nice. The verdict on the base is mixed: The pleasantly large base prevents wobbling and the extremely non-slip surface on the upper side literally claws into the soles of the shoes. However, since there are no nubs or the like on the underside, the pump tends to slip on smooth surfaces. The pressure gauge makes a really good impression. It is sufficiently large and easy to read even in poor lighting conditions.
A real highlight is the switch hitter pump head of the Air Tool HP. It automatically recognizes whether a Schrader or Presta valve needs to be inflated and adapts accordingly. In practice, this technique works extremely well. The clamping lever is also smooth-running and the head seals very well. The pumping feeling of the Specialized pump is very good. The piston runs smoothly and the effort required is low. The Air Tool HP excels in its special field – thin tires, high pressures. No pump needed fewer strokes until the tire had reached its 8 bar. We were surprised by the equally good performance with thicker tires: Here, the pump was also able to place itself in the middle field, despite the wrong area of application.
