The Mountain isThe perfect just-in-case pump, its relativity lightweight, easyTo use and wont breakThe bank. AnyValve head works with Presta, Schrader and Dunlop valves automatically Solid performance and exceptional value Aluminum barrel Ergonomic handle Approximate weight 162 grams Max pressure 90psi
Strengths: Works on any valve, very convenient if your friend with presta valves needs some air
Weaknesses: The mount piece is very poor. It only attaches to the frame in the same place where you can attach a water bottle holder, which on some frames puts it frustratingly close to the pedals. I found on my second ride that the mount had already broken, the cheap plastic takes very little punishment.
I would buy a different pump simply due to the poor quality of the mount, and the inconvenience of having to find some other way to carry it on a ride
