I have no idea why no one has thought of this yet! These sell at a bike shop for $5-10 for a pair. If you have a presta tube and a schrader wheel, pop this lil guy in there and you wont have to worry about your tube bulging out of the oversized hole and popping your tire!I've included different sizes for different types of wheels(single, double, aero, etc).... Enjoy!
