Ah, of course, vertical dropouts... Well, before Cipo, before vertical dropouts, slipping wheels in horizontal dropouts was not a problem. I'm talking here of pros and Campagnolo QRs and Campagnolo horizontal dropouts. If it was a problem there would have been a change.

I'm not talking about current QRs made from aluminum, composite etc. without enough clamping force to keep from slipping in a horizontal dropout, which of course would be off topic.

Also, making allowances for the axle compression from the QR closing force affecting the bearing clearances was common knowledge "back in the day."
