Very cheap light plastic, I doubt it will last long. I prefer my Leyzne with the flexible hose connecter, which I've had for years and still works, but takes a lot of effort as it is only a one way pump.
This pump is used mainly for mountain biking. The included mount fits well under my bottle cage and the pump is well secured to it. I happen to have a Shrader valve infant and a Presta on the rear but the switch over on the Blackburn pump makes that simple.
