This morning my chain locked up whilst I was standing on the pedals, causing the wheel to be pulled out of the dropouts on my 456 (which I have singlespeeded)
Now the wheel touches the drive side chainstay. Turning the wheel the other way round it still touches the drive side chainstay.
I have looked and it seems that the whole rear triangle is now out of alignment (and checked with a second wheel).
Can this be fixed (if so how) or do I need to get a new frame?
