There has always been debate surrounding whether cyclists really need to shave their hair to make them faster. Some say leg hair needs to go, some say beard hair needs to go, some say both. Before these questions are answered, lets look over some of the reasons cyclists shaver their legs in the first place: - It makes getting massages easier. - It looks sexy and lets you show off your diamond-cut calves. - It makes cleaning and treating wounds easier and speeds up healing. - It's a tradition and part of the sport. - It makes you faster because it's more aerodynamic. Well, the boys at specialized wanted to test the last reason. it makes you faster because it's more aerodynamic. Recently, they set out to determine whether shaved legs were in fact faster than hairy legs. They tested a number of riders "across the entire spectrum of Chewbacca scale," eventually choosing one cyclist, Keith, who had level-six hairiness — "fairly dense follicles." "They tested him with hair, and then they tested him without hair, 10 separate times. The results? They were "shocked" at how big of a performance difference they found. Over 40 kilometers, or about 25 miles, Keith saved 82 seconds — nearly a minute and a half. Although they found that Keith was on the high end of performance savings, even a rider on the low end could still save 50 seconds. That's huge. On average, that's about 70 seconds saved just by shaving your legs. After hundreds of hours of testing in the wind tunnel, the guys at Specialized said this was the most surprising revelation they have ever had."
