Why Cyclists Really Shave Their Legs: The cycling columnist for The Guardian has something to get off his chest today about his silky-smooth shaven legs: Cyclists don't do it for aerodynamic reasons. "Experts may try to tell you instead that smooth legs are worth a couple of seconds a kilometre, so this male depilation can mean the margin between victory and defeat," Matt Seaton writes. "But if this were true, we would all be shaving our forearms. And perhaps our eyebrows, too. ... we shave our legs because we think it looks good."
