I posted about this in mechanics and someone mentioned checking here. I have a univega hybrid frame I've turned into a poor man's cyclocross bike and have an adapter claw for my RD, I was hoping to find a solution for the non-drive side to make wheel changing less finicky as far as alignment goes (the frame doesn't have a slot for screws that I've seen some bikes have). I think there may be something that I've seen called an "alignment stop" but can't seem to really nail down an exact name or where one could obtain this these days. If anyone has any leads, I'd love to hear them! Thanks!
