ti can seem haunted when you try to alter it, even something as simple as a bent hanger. That sort of thing is probably for the frame manufacturer, or at least a frame builder experienced with ti. I say "haunted" because I have "straightened" a hanger on a ti frame, only to come back to the shop the next day and find it right back to it's pre-straightened (aka bent) state..... Which begs the question, "why didn't it just go back to it's aligned state after being being damaged, if it's going to pull that "memory" stuff, lol.

Not to make light of the situation, but ti is quite different than other frame materials in terms of working it during the building of the frame and also post-manufacture, regarding repair.
