My rear derailleur hanger went yesterday on the commute home. Luckily it was as I started off again after a turn. Still managed to take out 2 spokes itself and possibly the derailleur itself. Luckily, I had spares back to my knackered old Shimano for now.
The community bike workshop in volunteer sees this fairly frequently, you really sent it to break 2 spokes, must have been going fast. Good luck on the repair, feel free to message me or reply to this if you need any help and I’ll do what I can.
