A leg that's free from hair moves swiftly through the air
Non-cyclists simply don't understand why many male bikers shave their legs. The most used excuse is the aerodynamic benefit of baldness. Oops! While leg shaving makes your muscles look nicer and road rash easier to clean, no academic study shows any kind of significant advantage in terms of speed.
But before you bin the razor, the same is not tr ue if you plan on dabbling in triathlons. Given that water is around 1,000 times denser than air, the resistance hairy legged athletes face when swimming is more of an issue. Several studies have proven that body hair removal can reduce the drag effect significantly. One study even found that swimmers achieved 10 per cent greater distance with each stroke.
