Test: For a long time now, Specialized has not only been known for its bikes - the US manufacturer can now also refer to a really extensive portfolio in the accessories and clothing sector. Of course, hand pumps should not be missing either - today we are looking at the Specialized Air Tool MTB, a model especially for mountain bikes.

[/easy table]Anyone who knows the bikes and the accessories from Specialized knows that the workmanship is usually at a very high level. This also applies to the Air Tool MTB: Made entirely of black anodized, finely ribbed aluminium, it is not only a pleasure to touch, but also looks very good. Of course, it is also immediately noticeable that the pump is quite large: with a length of 245mm, it is no longer a real mini pump, but still a good deal smaller than most "full-grown" counterparts. A jersey pocket is of course not an option, but most trail and enduro backpacks should have more than enough space for the pump. If not, Specialized also supplies a frame mount that can be screwed to the bike instead of a bottle cage.
In contrast to the metal body, the pump head is made of plastic, but it doesn't make a cheap impression. The valve is clamped using the metal bracket on the back of the pump. This works very well and keeps the pump where it should be. As with most of its competitors, the head is compatible with Sclaverand or car valves. To switch from one valve type to the other, the insert must be turned inside out. Not a big problem, especially since you don't usually do this too often - nevertheless: This is solved more elegantly with some other pumps.
A simple aluminum air cylinder is used inside, which makes a really high-quality impression. It runs extremely smoothly and even after many thousands of pump strokes we can't find any play or other wear. In view of the size of the pump, we were not particularly surprised by the overall very good pump performance: after 200 strokes, we had inflated our test tire (29 inches, 2.2″) to 1,73 bar. A very good value, especially since the hand forces were really extremely low and the pumping itself was therefore much less sweaty than with some smaller pumps.
