I had a flat tire and replaced the tube. I just didn't realize that the tube was a thorn-proof tube when I bought it. It was the only spare one I had, so I used it anyway. Just now I replaced it with a regular tube. I figure I can keep this thorn proof one around just in case I get another flat.
The problem is, I can't get all the air out of the thorn proof tube to store it in the closet. It's schrader valve. I push the pin in and air comes out, but there is still a lot in there. I'm trying to fold it up like a tube of toothpaste while pushing the pin, and it's not working so well. I could cut it and patch it, but then I may as well throw it out and buy a new tube. Is there maybe some way to get my bike pump to work in reverse or otherwise completely deflate this thing?
