GT Course 853 - Rust Repair
A friend of mine picked up a GT Course 853 road bike (1998?). This bike came with an Ultegra set. I think this was a TIG welded frame and has severe rusting at the stays-to-top tube connection and also some pitting/rusting at the tube intersections with the bottom bracket. It is in otherwise clean condition. Here's an example, I can provide others:
He is riding the bike and he is not shall we say, dainty.
Is this frame toast or can something be done? I was thinking perhaps a frame strip and a bead blasting followed by silver brazing the pitted (holed?) tubing but I don't know. The rusting seems to be localized to the welded areas which makes me wonder about some deficiency in the welding process.
