just now on my way home from work I came to an almost catastrophic stop . I was in traffic and all of a sudden what felt like my breaks slaming on my rear wheel even though a didn't touch them . I got off my bike and expected can't find what's wrong . It is my rear wheel and it has turned to the right so far that its rubbing almost stuck to the chain stays any idea what's up ??? Possibly helpful info it seems almost bent to the right though the rim is not bent. It's "bent " in the direction where my pannier hangs I.e. where the weight is I have maybe 15-20lbs hanging on it and another 5 max from a lunch box ontop of the rack . What I think maybe the rear drop out bent outward although doesn't look so and second maybe hub bent ?? Idk if anyone can help asap I'd be greatfull . Oh and the bike is am 1988 roadish bike I don't think it is ment to carry things since no dedicated rack mounts just fender mounts and I have aluminum Rims . HELP!!!!!!
