These experts tested 12 all-out aero bikes in a wind tunnel to find out which was the fastest bike in the world.

The team over at Cyclingnews decided to put 12 of the latest aero bikes to the test.

It would be in the wind tunnel over at Silverstone Sports Engineering Hub that they’d be put through their paces.

The team wanted to know one thing – which of these bikes came out on top?

Putting these aero bikes to the test in a wind tunnel

Before we get into the results of this test, let’s just clarify what an aero bike is.

Otherwise known as ‘Aerodynamic bikes’, these road bikes use aerodynamic principles to maximize speed.

This is often done through features like integrated cable routing, a lower riding position, and aero-shaped frames.

You’d most often see these types of bikes in competitive racing.

So these bikes are built for speed, there’s no doubt about that.

But the real question is – which of these bikes comes out on top when put to the test in a wind tunnel?

The team over at Cyclingnews brought together 12 aero bikes and put them through their paces in the wind tunnel at Silverstone Sports Engineering Hub.

The bikes that were tested included:

  • Argon 18 Nitrogen Pro (pre-production prototype)
  • Bianchi Oltre RC
  • Cervélo S5
  • Colnago Y1Rs
  • Cube Litening Aero C:68X
  • DARE Velocity Ace-AFO
  • Elves Falath EXP
  • Factor Prototype
  • Merida Reacto 9000
  • Ridley Noah Fast 3.0
  • Scott Foil RC
  • Van Rysel RCR-F
  • 2015 Trek Émonda ALR

To represent the speeds achieved in races, the wind tunnels were done at around 40km/h.

Three different setups were rolled out – the bike with its stock wheels, the bike with a standardized set of wheels, and one with a rider.

The three setups drew some different results.

In the bike-only tests, the Factor Prototype came out on top as the fastest.

In the test with a rider, it was the Cervélo S5 that reigned supreme, but it was a close one as the Factor Prototype was chomping at its ankles, so to speak.

It’s not just cars packing serious speed

Bikes may not have the revs of supercars, but these things can still go seriously fast.

And in some cases, they can cost a pretty penny, too.

Japan’s Olympic track bike even costs more than a brand-new Porsche 911.

Then there’s the AeroVelo, the world’s fastest human-powered bicycle.

Bizarrely, it was shaped like an egg.

Now wouldn’t you have liked to have seen that in a wind tunnel?
