Giant's Control Tower Pro is a shop-quality pump for serious mechanics. In fact, it can get a tire up to 100psi in just 24 strokes. It utilizes a barrel-in-barrel design housed in a rugged aluminum casing so dings and dents don't affect its function. All fittings are made from anodized aluminum for leak-proof durability and are fully user replaceable, in fact, the Pro comes with extra O-rings and valve seals. Plus, it has a highly visible gauge and a pressure-release valve so you can get the pressure just right every time. Of course its thumb-lock head fits all valves and this sweet pump has a long hose, too, for extra reach.
