If it is the mech hanger, if you don't have a tool like a Park DAG-2 you may struggle to get the correct alignment for the hanger.
The derailluer may have also been broken by the spoke interaction, and that chain could do with some lube, are there any stiff links in it which caused this?
You will get more answers posting this sort of question in the Bicycle Mechanics forum, rather than the Road Cycling one.
Is this the derailler hanger (See yellow arrow):
that u said i have to check for if its bent or broken?
Well tbh i just bought this bicycle from garage sale. After two days of riding it. It started to run stiff like i would ride it for 5 seconds and it wouldnt go forward at all seems like something was stuck somewhere so i checked if it was the brakes being too close to the tire - that wasnt the case so i tried changing the gear and all of a sudden this happened - derailler got stuck.
Yes i will lube the chain.
Sorry i am new here. I would appreciate if someone can move this thread to mechanics forum. thx
