Profile Design CO2 Inflator

Use pressure to your advantage with Profile Design's CO2 Inflator. Screw on a CO2 cartridge (sold separately), and this chuck is ready to air your tires up to pressure quickly and easily whether you're out on the race course or in the garage prepping for a ride. It's push-activated so you can use only as much CO2 as needed for the inflation task at hand. It's also small enough to fit almost anywhere so you'll always have it along. Best of all, no arm-numbing pumping is required!
