Good for you! It is no small thing for many. I am finally at a point where I feel pretty confident in changing a tube ... but it's putting the back wheel on that still freaks me out a little ... after 4 1/2 years of riding. Haven't had to do it enough to really get the hang of it. I can do it, but it generally takes a while. DH did a hands on lesson with me about six months ago, having me take it off and put it on and take it off and put it on several times. However, 6 months later, I still haven't had to do it for reals yet and who knows if I'll remember what he taught me when I need it?! I guess I should have another practice session at home.
