if you carry them in a seat bag with tools, tire levers, etc. Otherwise there's a good chance that when you need it, you'll find it has a hole torn in it. But the boxes are bulky, as you say. I repackage the tube in a heavy-duty ziploc bag, squeezing out as much air as possible, and then wrapping it with a couple of rubber bands to keep it all neat. The bag also allows you to dust the tube with talcum powder (aids installation), without having a mess. Partially inflate the new tube, coat thoroughly with talc, then completely deflate, roll it up and seal it in the bag. It'll be ready to go when you need it.edhchoe said:Thank you!
Another question... Do you carry the tubes with the box? It is rather bulky.
