I'm looking at buying a 2006 Giant OCR Composite 3 and once money changes hands, I'm stuck with it.
What I can't seem to find are any web pages that tell what to took for so if you know of any, let me know.
I can visually inspect a framset for scratches and gouges but I need to know what parts of the frameset- top tube? seat stays?- usually have the most damage from crashing, falling over, etc.
Also, how deep of a scratch or gouge is considered to compromise the integrity of the frame? 2mm deep? 3mm deep?
Last, are there areas of the frameset that are most easily compromised by a scratch, like the bottom bracket or head tube areas? What part of the frame, if already damaged, would most likely catastrophically fail when I hit a pothole or when sprinting out of saddle?
