"What Our Gearhead® Experts Are Saying: ""I always carry this inflator on my gravel rides. It’s compact enough for a jersey pocket, and I love having the CO2 for fast fixes and the manual pump for peace of mind.""We never want to get caught unprepared, which is why the Air Smith CO2 bike tire inflator and mini pump lives in our saddlebag or jersey pocket every ride. Planet Bike designed this clever tool with both a CO2 inflator for quick fills and a backup mini pump for those days when cartridges run out. Built from lightweight and durable materials, the Air Smith CO2 is a smart addition to our roadside repair kit. At just 150mm in length, it tucks away easily, yet delivers big when we need it most. And with compatibility for both Presta and Schrader valves plus all threaded CO2 cartridges, it’s ready to rescue us from flats anytime, anywhere."
