Cyclists, from Team GB athletes to daily commuters, understand the importance of marginal gains. They constantly optimize their nutrition, equipment, and position to improve their race times by reducing drag.
It’s not surprising that some middle-aged men in Lycra (MAMILs) are considering shaving their legs. The idea is simple: removing leg hair can reduce drag, the force that slows down objects moving through the air. And on a bike, air resistance is the main factor that hinders speed.
When you’re cycling, the air in front of you moves as you move, creating wind resistance. To enhance aerodynamics, it’s crucial to optimize how the air flows around your body, reducing drag that holds you back. This is why cyclists wear skinsuits, position themselves low on the bike, and helmets are designed like sports cars.
There’s ongoing debate among riders and engineers about whether shaving your legs actually makes a significant difference in speed. An interesting study by a bicycle manufacturer tested shaved legs in a wind tunnel and found a 7 percent reduction in air resistance compared to natural legged riders.
In a 40 km time trial, this improvement could potentially give you a 79-second advantage over competitors. For professional riders, this could mean the difference between winning and losing.
