guys, i took off the rear wheel to fix a flat, only to have the washer-like piece which sits on the inside of the dropout fall apart. i assume it was broken from tightening down too much, and just fell off when the pressure was released.
i was somewhat concerned at the thought that, if the pressure wasn't holding it in place to maintain the spacing, the axel would have loosened on one side. not sure what the ramifications could have been, probably something along the lines of me eating the pavement.
this happened to anyone else before?
