[QUOTE=Andrew R Stewart;19076765]Relying on gravity to align a cable with it's exit port is a fool's errand. /QUOTE]
Why do you feel that it's necessary to disparage somebody else's experience?
I have personally done it successfully many times. The most recent involved a Klein bike that had some pretty small exit holes under the down tube. It didn't take me much time at all. Most times it takes longer to figure out how to position the bike than it does to run the cable.
