I have noticed this and my interest was peaked again by my buddy $Bill's blog post mentioning seeing one. Today, while running with my other buddy Frank, we passed one and Frank mumbles, in a particularly important part of my running story, "i hate that!"
"That" would be cyclists who ride with their shirts unzipped. Just to clarify, "that" would be male cyclists.
Why do they do that? Is there some scientific reason behind this? Like it makes you faster to show your chest? If that's the case, then why not go shirtless?
I don't get it and I personally don't like it. It has a lot of machismo behind it, which is very cheesy. Cheesy in the stereotype of a "guido" that wears a see -through black shirt, or a button down shirt unbuttoned to below the ribs, very similar to these guys with their shirts unzipped.
Is it supposed to be cool? I just don't get it and I don't get it because I see it so often.
I'll be interested to hear what the reason is behind this style. And I'll be the judge as to whether the reason sounds reasonable or not...:-)
