brazed on under BB cable guides

I am crossposting from the bicycle mechanics forum:

Does anyone have brazed on under BB cable guides?

I am wondering how you prevent paint damage and frictionless operation. I have always had the plates with the mounting holes before. I would clean them till they need replacing.

The LBS should have teflon or delrin tubing that has in inside diameter slightly larger than the outside diameter of the derailleur cables. A six inch long piece of tubing protects the paint and is slippery enough so that cable wear is minimized.

Thanks I will check with my LBS.

Over on the bicycle mechanics forum, I got grief for my use of the term "frictionless".
Before anyone here begins, let me make it clear: I meant "less friction".
