Nobody likes to think about flats, but they happen. When it happens to you, be sure you have the Topeak Pocket Rocket Mini Pump. This little pump weighs just four ounces, yet packs in up to 160psi--more than enough for most riders. It is compatible with Presta, Shrader, and Dunlop valves, ensuring you can loan it to a friend if something happens during your ride. Its alloy construction is lightweight yet durable, and the plastic handle provides a comfortable, secure grip so you can focus on pumping.
