Endura Drag2Zero Aeroswitch Helmet Review


Endura have been at the top of the aero game for a number of years. With many of the worlds top time trialists and triathletes wearing the Scottish brand. Pro cycle team Movistar, Ironman World Record Holder Tim Don, Kona Runner Up Lucy Charles, it’s clear Endura really know how to make aero kit among the best in the world. The new and updated Drag2Zero helmet is full of cutting edge technology keeping it right at the top end of the market.


Designed by aerodynamicist Simon Smart his collaboration with Endura strives to push the technologies and create the most advanced kit available. Combing his wealth of experience at Mercedes F1 with some small pieces of Fabric 350 miles North in Livingston, Scotland has produced some great results. The collaboration relies on rapid prototyping in a real sense rather than 3D printing to maximize turn around speed.

Endura made the Drag2Zero helmet with one thing on their mind, they wanted to create a helmet faster than any other in the world. Endura have claimed some phenomenal results from the wind tunnel testing of this helmet so we’re incredibly excited to see how it holds up on test.
A huge amount of testing, prototyping and modelling has gone into the Drag2Zero Helmet in the wind tunnel. This was then mixed with some of the worlds best engineering along side a huge knowledge of helmets and going fast. The profile of the helmet provides some great airflow but also minimizes the negative effects from the increased yaw angles.

The helmet strives to be one of the safest helmets on the market too with Endura’s own Koroyd technology built in to decrease the impact in a crash. The magnetic visor provides deep eye protection and a fantastic range of visibility whilst not detracting from the ventilation through the helmet. This can be easily flipped up as we’ve seen in other aero lids.


The Aeroswitch’s name hints at its hidden feature of a patent pending* detachable aero tail which clips off to create a shorter, more open road aero helmet. Large front vents achieve an increased airflow, while the one-hand micro-adjustment fit system lets you adjust the fit easily. Covering all possible eventualities we’re excited to see how this Drag2Zero Helmet impacts the time trial and road cycling scene.

Our Verdict:
The helmet certainly looks the part and is exceptionally fast. With the flexibility to change between road and time trial, it immediately eliminates the need for multiple products. Although the product is heftily priced at £330, it still weighs in cheaper than two helmets at an equivalent standard. We’d say it’s definitely worth the investment.
