Nashbar Deluxe CO2 Inflator. Tire inflation has never been as quick and simple when you've got a Nashbar Deluxe CO2 Inflator along for the ride. Simply lock the inflator onto the valve and control the CO2 flow with the trigger. The gold anodized head and trigger add some sweet style plus it's all amazingly compact and light to boot. The 16 gram threaded cartridge can fill a road tire to approximately 125 135 psi or a 26 mountain bike tire to 40 psi. Important Note: Use only 16 gram cartridges with the Nashbar Deluxe CO2 Inflator. Either threaded or unthreaded cartridges will work, but be aware that threaded and unthreaded cartridges are different lengths. Overtightening the threaded cartridge may damage the cup threads, posing a risk of injury.
