See this: I sort of disagree with some of things he says but that doesn't mean he's wrong and I'm right it's just that I do it differently. For example he says to carry two tubes, I don't think that necessary because I can fix a flat on the side of the road and patch the flatted tube almost as fast as I can replacing the tube. Also he puts on gloves, ok fine, I use little towelettes and wipe my hands afterwards, no big deal either, but the last thing I want on my hands on a hot day is gloves that don't breath.

Note on the film he sets the bike down, that's fine, that's how I do it, just don't set it down on the derailleur side, and make sure as you set it down the chain doesn't do something weird. Also pulling a tube out in the matter shown is ok as long as the tube is made of butyl, a latex tube could rip apart if pulled like that. He also uses a CO2 inflator which I don't like at all due to the limited amount of air you can carry, I don't like paying for air, and I don't like doing things twice, with CO2 when I get home I have to drain the CO out and replace it with normal air because CO bleeds out of the tube and can be flat in 36 hours, and if you pump it up the next day without first flatting it to get all the CO out then in about 48 hours the tire could be flat again! Also with CO2 you have to contend with the waste of the cart, some riders just throw on the side of the road and ride away...PLEASE don't do that!!!! The pressure he talks about should correlate with his weight, the other guy shouldn't even ask that unless he weighs exactly the same. I also didn't notice if he ran his hand along the inside of the tire feeling for a protruding object nor look on the outside for one (though I did speed through it so I may have missed it), you need to do that before you put the new tube back in or else the object that flatted you could still be in there and flat you again.

Now as far as me being able to fix a flat as fast as replacing a tube and probably faster is a technique I used for years that an old man taught me. Most holes where the flat occured can be found quickly with just a visual inspection of the tire, if you find the hole then simply leave the wheel on the bike! And remove about 1/2 of one side of the tire with the middle of the half where the hole was, next pull out about a 1/4th to a 1/3rd of the tube with the hole again in the middle section. Check to make sure no objects are sticking out of the tire on the outside nor on the inside. Patch the tube, I use glueless tubes from Park, they hold up forever and i don't have to wait for the glue to dry. Restuff the tube and install the tire, inflate and ride away. If I can't find the hole initially I still prefer to find the hole before I replace the tube. In that case off goes the wheel, pull the tube and inflate the tube to about triple it's normal size when in the tire and move the tube slowly past my lips till I feel the air, deflate and patch. If I still can't find the hole then I'll go to the backup tube and wait till I get home to fix the old tube. But about 75% of the time I can find the hole without ever removing the tube, and then about 95% of the time after I removed the tube I can find the hole. This way when I get home I don't have to worry about fixing a tube. So about only 5% of my flats I have to use the spare tube.

If you like the idea of CO2 you can get a hybrid pump which is a pump and CO2 inflater in one, so you can use the CO2 to fill your tire but if you get more flats than you have CO2 for you can use the pump. I l like the Lezyne Hybrid, it seems to be built better than others I've seen.
