Once again, a warning that really only applies to brakeless, yet one that we all sheepishly heed.
Geared bikes used to come with horizontal dropouts. The Bianchi Volpe and the Castro Valley both still do. And they have quick releases.
So what is the issue? Obviously the quick release is strong enough to have withstanded the stresses placed on it by a road bike. Why not a fixed gear? As long as I pay attention to whether my chain is flapping in the breeze or not, and as long as my chainline is nice and straight I don't think I have much to worry about with a quick release.
If I have brakes, that is.
