Topeak Two Timer CO2 Inflator / Pump

In this case, two-timing is a good thing! Inflate it, pump it or do both—it's your choice. Fits both Presta and Schrader valves; dust cap protects valve hole. Pressure indicator lets you know whether your inflator is empty or armed. Sturdy aluminum barrel. Includes one 16 gram, nonthreaded CO2 cartridge.
