Only high volume minipump I could find. Use it for 26x4,8"" fatbiketires. In about 100 strokes it will inflate from about 0,5 bar to decent pressure for road use, in my experience. Very helpful when fixing a flat during a trip. Aluminium body is durable and the head works well with both Schrader en Presta valves . I keep it in my framebag, dry and clean. Good product
