This handy little gadget is called the Bullet Keychain Presta Valve Adapter. It is a solid brass Presta valve adapter that enables you to get air in your tires wherever there is an available air pump. One of the best things about it is that it’s a key chain, which would help prevent the valve adapter from getting lost. The Bullet Keychain Presta Valve Adapter costs only 7$, and some of the profits are donated to the Intrepid Fallen Heroes Fund and Dollars for Change. Go to The Bullet Keychain Web site to purchase.
