Great little made of a metal bike pump. It is perfect for traveling as you can attach it to your bike with an included mount or even carry it in the backpack. It is super lightweight and small which makes it easy to carry it around. The pump has a plastic cap on the valve and lock when you start pumping the tire. In the set are two different types of valves, Presta and Schrader so the pump can fit any tire. It is also good for pumping footballs.
