Not sure what happened...was just riding along, did a double shift (53-21 to 39-17), heard a double CRUNCH then the back wheel locked up. Looked down an FUUUUU.........!!!
It's worse in person.
Stripped the frame down last night & contacted a local frame builder - waiting to see if he can bend back into place and align the hanger.
Scott B. - Any concerns with cold setting the 4130?
...time to go Shimano (if only for ease of replacement)
From doing this a few times at the service end of things, there will likely be some cracks in the paint. A neutral clearcoat/nail varnish will help before you put everything back together.
But - as yonatey mentioned - do you have another derailleur in the wings?
Wow, maybe odd to say but those pics are such a relief.
Steel is real.....repairable.
Repair looks great!
