Review on WOTOW Bike Tire CO2 Inflator With Storage Case, Presta/Schrader Valve Adapter, Insulated Sleeve, And Glueless Tube Patch Kit - Quick And Convenient Tire Inflation Without Cartridges by Jeff Warne

This CO2 tire inflator has nozzles for Presta and Schrader valves.There's really no mystery here. After you patch or (preferably) replace the inner tube on your bike, just insert a CO2 cartridge into the inflator, choose the correct size valve stem for your bike, attach the inflator, activate the CO2 canister and you'll be back on the road in short order.BTW, if you don't have a new tube with you, this product also includes a patch kit. I have to admit that my success with patch kits in general has been quite spotty over the years, but it may give you enough support to get you to help.5 stars
