Good for you!!! I'm very lame because I still haven't ever changed my own tube. I've never even had a flat and the one time I changes from knobbies to slicks on m mountain bike my husband was in a hurry and just did it for me before I had a chance to ask him to show me how.

I know I know, that's something I really need to learn. Even the Kevlars might get a flat someday.
