We know that statistically cycling is a more male dominate sport. I think even just the sight of a woman makes you stand out, and for those men inclinded, they begin to yammer. If I run an errand straight from spinning and have on my cleats it never fails that a complete stranger of a man will approach me. Or just even looking at bike gear anywhere. I just usually smile and nod if I have a moment to listen. I think if they have nothing else they can talk about, it's an opportunity to feel an ease with a subject they know (or think they do) and blab to a pretty woman. Chivalry (they are trying to rescue you from your statistically newb self)... through manly man eyes.
