is this going to have an effect on the integrity of the frame? and come to mention it the general rust that is starting to show up, it’s potentially for the missus, so i dont think it’ll get a repaint either
Normally there are holes to let excess water out, these look like drilled to knock rust out or add super glue to make the rust stick to the wall of the seat stay, well that’s my theory anyway and I’m sticking to it.
