I use a bicycle to get work and I really hate flats! I have the thick armadillo tires and thick tubes and I keep the air pressue at the proper level, but sometimes I get flats. I always hear about how easy it is to break down the tire and fix the flat and have the tire back on in 10 minutes or less, but that never happens to me! Plus, the glue doesnt seem to want to work as advertised. What a pain! So how do you change a flat and how long does it take you?
