Video: Changing a Flat Using a CO2 Cartridge 

By Troy Jacobsen

You're out on a ride and, ppsssstttttt....the sound of a flat! Oh no! What do you do now?! Hopefully you're prepared with the right tools and knowledge about how to change the flat on the road so you can finish your ride. In this short video, I demonstrate how to quickly change a clincher tire (tube) using a standard CO2 Cartridge. Practice this at home so that when it happens on the road, you're ready for it!
