Comprehensive Insight into Cyclingnews Labs' Detailed Technical Evaluations Across the Spectrum
In the world of cycling, every second counts. That's why Cyclingnews Labs, a platform dedicated to testing various cycling gear, conducted an extensive wind tunnel test to determine the fastest and most aerodynamic helmets on the market.
The test, held at the industry-leading Silverstone Sports Engineering Hub, compared 47 helmets from 18 brands, making it the most comprehensive wind tunnel test of aero road bike helmets ever conducted. The test was designed to simulate real-world wind conditions on the road, measuring aerodynamic drag in watts at speeds of 40 km/h and 50 km/h, across yaw angles from 0° to 15°.
The test results, quantified using CdA (coefficient of drag times frontal area), provided a highly detailed ranking of the helmets. Among the tested helmets, the Procen Air - complete with visor - emerged as the fastest, offering a significant advantage in aerodynamics.
The test considered the variability of rider wind direction, capturing not just raw speed but aerodynamic efficiency across angles and speeds. While other tests, such as the 220 Triathlon test of 14 aero helmets and individual helmet tests by BikeRadar and CyclingNews, provide valuable insights, they lack the broad scope and data richness of the 47-helmet group test conducted by Cyclingnews Labs.
Subscribing to Cyclingnews provides access to a full library of in-depth lab tests and tech content, including the detailed data and findings from this comprehensive wind tunnel test. For those seeking to ride faster and further, the insights and findings from this test are invaluable.

Science and technology played significant roles in the wind tunnel test conducted by Cyclingnews Labs to determine the fastest and most aerodynamic helmets. The test was designed with precision, employing advanced equipment such as Silverstone Sports Engineering Hub, to simulate real-world wind conditions and measure aerodynamic drag, resulting in a detailed ranking of the helmets.
In addition to Cyclingnews Labs' comprehensive test, other tests, like the 220 Triathlon's test of 14 aero helmets and individual helmet tests by BikeRadar and CyclingNews, also contribute valuable insights to the world of cycling, but they lack the broad scope and data richness of the 47-helmet group test.
