CO2 Inflator/Pump
This versatile design combines the convenience of a CO2 inflator with the added security of a mini-pump. An innovative double-ended design- CO2 inflator on one end, mini-pump on the other, features inflation heads that fit both Presta and Schrader valve stems. The CO2 inflator system can accept either threaded or non-threaded 16g cartidges and utilizes a durable aluminum valve for long life. A compact thumb lever makes CO2 regulation easy and precise without interfering with spokes.
