Yeah, I do enjoy knowing my bike is going to work when I need it to and something is going to fall off or break. (It can happen, but when you have things in good working order, it is less likely to happen)

I stripped down one of my bikes to the frame two years ago and built it back up, re-cabled it, repacked wheels, etc. with my father. It was a fun time with him and a GREAT learning experience. I can do just about all my own work, though derailleurs and getting the perfect tension does sill scare me a bit.

Oh, and I used an equation the other week to cut a chain to the proper length. I'd always had the proper length chain on a bike, but this was the first time I did it this way - felt like a hybrid math/bike geek (though the equation was pretty simple).

It is a superb feeling to have all of your bikes in fine working order; I love getting up in the morning and being able to say, "Which bike do I feel like riding today?"
