Just be careful with those Campus pedals.. they tend to flip over because one side is weighted with the cleat. So, if you are kicking the pedal over to flip it to the flat side, you might accidently clip in! I don't think it could happen very easily, though. I have these pedals on my hybrid (though I barely ever ride on the flat side) and my mountain bike, where I do frequently rest at least one foot on the flat side.
