Ha, I'm just like lph. I don't remember ever not knowing how to fix a flat ... and I don't remember my parents owning so much as a screwdriver. They must have, I suppose, but it wasn't part of our home culture. When I was about 15 I disassembled a freewheel, down to the pawls that went flying everywhere, just because. :D And got it back together and working, with nothing but a kid's perseverance, cheap hardware store tools I bought for myself, and some paperback book that I don't even remember the title.
I let the LBS replace my freehub last summer, although when I found out that the guy used YouTube to learn how, I kind of wished I'd just gone ahead and done it myself. :rolleyes: And I'm a little intimidated by bleeding hydraulic lines - I don't have any on my bicis, but I always get DH to supervise when I change the brake fluid on my motos.
I haven't had a headset, bottom bracket or hub apart since I was in my 20's. I'd probably be a little shy about doing it now. :p
