Bontrager's Super Charger is a shop-worthy pump for the home mechanic. The base, barrel, handle and gauge are crafted from aluminum, so it's tough, durable and lightweight. Replaceable internals extend the life of the pump. It's also got an extra-long hose, an easy to read gauge, and an auto-select head that instantly fits both Presta and Schrader valves. A clever, built-in air release makes it easy to really dial in your pressure. And the comfy handle and large, stable base assists pumping and minimizes tipping, too.
