Slime Tubes rule in the desert! I got tired of having rides interrupted by flats, especially in the summer heat. With slime tubes, you whip out the CO2, pffft, spin the wheel, and ride on! It's amazing how easy it is. Every so often, you will get something major that will not heal this way, but I've nearly a year on some tubes. When they start to have slow leaks, or when I change tires, I change the tubes in the comfort of my garage, at my leisure. What's amazing is how many tiny thorns I find embedded in the tire, and little flecks of slime, where the tubes saved the day. Tweezers are best for getting those little babies out of there; it's easy to be patient and get every one out when you're not out on the trail, holding up your friends. So, count this as a big vote for SLIME! It's probably cheaper to buy the bottles and do it yourself, but it's so easy to buy the ready made tubes. They're really not that expensive when you consider they may outlast your tires!
