I was riding a 1983 MTB, single-speed until I discovered that the rear dropouts have somehow spread out and the QR skewer was warped, I suspect from having to squeeze and clamp the dropouts to the hub. It's currently out of commission until I can get it to a frame builder to have a look.
My backups are a true Frankenbike (it's even green) that is a 700c hybrid converted to 26" wheels and a occasionally a Handsome Cycles Devil. I don't have current photos of any of them. The middle bike has an MTB fork and the blue bike has mostly black components now.
