I want to get some cable guides brazed on to a (steel) 4X frame for a front mech. Probably under the top tube, to go with the rear guides, unless someone has a better idea.
Will it take a lot of the paint away? I don't really want to get the whole frame resprayed, is it OK just to touch it up with hammerite?
Has anyone had this done? Is there a better/easier way using bolt on guides or something?
