I have to take that back. That was not helpful. I don't like the stuff, however, some of you do. I prefer to patch clinchers and replace tubulars (back in the days when I used tubulars).

You should always have a spare tublular, they are easy to carry. Then patch them up when you get back home.

With clinchers, (normal tires) you should carry a spare tube or a patch kit. I always had a patch kit. With only a little experience you can get pretty good. I like the Tip Top kits best.
