Stupid Murphy

Why cant I ever get my canti`s set up right. Every time I try, I end up just making more of a mess out of it than where I was. Tonight I decided to put the new bar on the ciclocross, and swap out the stem, and put the old stuff on the slingshot. First problem, the new bars are not round so the cross top bars dont fit. Hmm, well I dont use them that much anyways, put them on the slingshot. Alright, so now I have to undo my canti`s. Well shouldnt be too much of a problem, just clamp it back down where they were before. Hmm, now the housings are a different length and so are the cables at least in relation to the carrier. The front went fairly smooth. The rear cable, though started to fray, then it wasnt long enough. Now it is fraying even more and still isnt long enough. So into the shop it will go tomorrow. I need a new front der. cable anyways, might as well have them replace them all. Why does it seem like everytime I try to do a simple project it turns out to be a mess? I guess that is the beauty of having a bunch of bikes though. Always something else to ride.
