I haven't bought new tubes in a couple years now. Both of my bikes have a small seat bag with a tube, patch kit (glue-type), and multi-tool, and a pump on the frame. CO2 inflators would take up too much room. CO2 cartridges are one use. Since I have had multiple flats on a ride, I want to be able to inflate a tire multiple times. Don't want to pump up a tire? You're out there riding your bicycle, are you afraid of a little excercise for your arms, too??

When I flat, I switch the tube out.When I get home I patch the tube, put it in a zip-lock with talc and reload the seat pack. I've had one flat on each bike so far this year. Both times it was right on the center seam. When I patched them, I carefully trimmed the seam flat to assure a good fix, no problems.

And what's with people leaving their old tubes (and CO2 cartridges) laying on the road? Are these the same pigs that leave their McDonalds garbage on my parking strip? Pack out your damn garbage, you lazy slobs!! Have just a little respect for the people and the world around you.
