I've gone and done it. Fixed my first flat!
On my way home from a 30km ride and psssssttttttt...the rear wheel goes as I climb out of the saddle up a hill...I had to ride on the deflated tire for a bit and was wondering if I could've done any permanent damage to the rim? Ideally would've like to stop but it's a narrow road and was more interested in getting somewhere safe to stop. Anyhoo, had to lug it home and change it. Am proud I figured it out (after an hour!) but am wondering now what would've happened if I was on the road with a hand pump. There is NO way I could've thrown 120 pounds of air into that tire. I guess most people just pump it enough to get them home?
