Video: Proof of time savings when cycling with shaved legs

Just how much faster you are cycling when you’ve shaved your legs is very surprising.


Time savings when cycling with shaved legs


Ever wondered about the aerodynamic benefit of shaving your legs for cycling and the time saved over a set distance? Well wonder no more.

The video below is one in a series shot by the major bike brand Specialized.

It tests a cyclist in a wind tunnel while his legs are still hairy. And then the testers shave his legs and sticks the cyclist back into the tunnel to be retested.

The results are absolutely amazing. The rider featured in this film is regarded has having medium hairy legs.

When he shaved them the wind tunnel data revealed the time saved was a whopping 82 seconds over 40km, or 25 miles.

Of the six cyclists with shave legs tested, the rider featured was on the higher end of the time-saving scale.

But the average time saving for all of those cyclists with shaved legs tested worked out at 50 seconds over 40km.

Those who carried out the tests reckon that’s about the equivalent to the saving gained by a rider swapping a regular tubed bike for one of the most aerodynamic and most expensive you can buy.

The two testers feature in the clip below said they had always been curious about how much time, and energy, cycling with shaved legs would save.

But they felt the difference would be so tiny it was not worth assessing.

Now they say that of all of the data thrown up in 1,200 hours of wind tunnel tests, the information on leg shaving has surprised them most.

If you are hairier than the rider in this film, the benefit to you will be even more significant.

And if you have hairy arms too, presumably giving those a blast of a razor will make you slice through the air even quicker when racing or training.

Happy shaving!


Here’s the proof…

The razor came out and the hair came off to compare hairy legs with their shaved selves.

The difference in appearance of the legs when shaved was significant. But many men would have hairier legs than this and if you’re one, then shaving will be even more beneficial than the set of test results suggest.
