I have an old Lotus frame from the early 80's with top-tube cable routing. The problem is that I can't seem to find brake cables that will fit inside the braze-ons - everything is too big. I wish I'd checked this before I had an expensive new paint job applied. If anyone has any suggestions on small-diameter housing brake cables, please contact me off-list. I hope to avoid having to replace the old braze-ons and the resultant repainting (hopefully partial).
TIA,
