hanger frame in so doing? Thank you and Happy New Year! FYI: This is a steel frame.
You should be able to drill through the bolt pretty easily w/ a good bit, I don't understand why this is a problem. Hammer a Torx bit in there.
ETA: This didn't happen because you shifted while climbing, something wasn't adjusted correctly. People shift in all sorts of situations. And it looks like your photos are flipped backwards, what's up w/ that?
