I've seen some articles about QR/front disk problems like that before, which was why I specifically mentioned that the bike has disk brakes in my story. Despite several reasonably forceful stops with a front disk brake with a loose QR skewer (pretty much a recipe for dental work, for reasons noted in the articles I've seen), the lawyer lips did their job in this case.
I've had the bike for a year and a half and have ridden about 6500 km on it. I've never had the QR loosen like that, which makes me suspect that I didn't clamp it quite as tight as I normally do.
