I don't believe that I argued that they are innately superior. I merely refuted that the benefits of clipless are a mere marketing gimmick. By conceding that there are benefits to clipless, you are reinforcing my argument. What's your beef then? What fallacy am I committing?

I will argue that under certain conditions they are more efficient. Climbing a hill, for example. Even the vintage-loving, all-old-stuff-is-good-and-new-stuff-is-inferior Rivendell guy agrees with that. Let's also take for example my commuting. I have a fixie and a 2x10. On my fixie, if I am focused on keeping my feet on the pedals, I am less efficient. Why? Because I can't focus on pushing the pedals. If I get to a high enough RPM, my focus shifts more to staying on the pedals than it does to keeping a round stroke, because slipping off the pedals while descending at a high RPM could mean disaster. Messing around with flipping over clipped pedals vs. stepping straight down into my double sided clipless pedals, which one is more efficient?
