I can't believe the members of a bicycle mechanics forum are actually telling someone not to take something apart and then try to put it back together again. People, this is how we learn how things work. If it weren't for the thousands of things that I've (albeit sometimes rashly) disassembled, only to reassemble later, I wouldn't have learned what I have about mechanics, home repair, computer repair et cetera. Seriously folks, where's your sense of adventurous curiosity?
