Cable housing routing question
I'm installing new housing and cable, as well as new levers and calipers, on my old steel road bike. This bike has 3 rings on the top for the cable to go through, giving a long continuous run from the lever to the caliper. Every other bike I own has braze ons where the housing ends and the cable is bare, and another at the calipers for the short stretch of housing.
Which method is better? And would there be any point in changing it to the other method, if I could even do that without sending the frame to be redone. I'm just curious really as I'm doing an upgrade on the cheap for this bike. The whole brake setup came to $88 so far, with Tektro levers and calipers, cables and koolstops. I've already tried the calipers while I waited for the new levers to come and they work so much better than the old ones. And the levers are nice Campy clones, they feel just like my Chorus on my good bike.
And since I'm asking, how do you cut housing cleanly anyway? From what I've read so far, even the Park tool doesn't leave a clean cut all the time. I tried the cutter that my son uses for guitar string and it gave a pretty good cut on the housing, but maybe I was just lucky on that one. Dremel is the one always mentioned, but I don't have one and I'm not buying one just to do this, although I wanted one for some other hobbies. Almost all the tools I have are for woodworking, so not much that could be useful there.
