Road Aero Helmets

I found an interesting article that Tested 3 Aero Road Helmets on the Velo News website today:

Five helmets were tested. Velo‘s 2014 Editors’ Pick road helmet, the Giro Aeon, was used to provide a baseline comparison. Giro makes no aero claims with the Aeon, touting only its low weight and exceptional cooling. It was not designed to improve aerodynamic efficiency.
Three popular aero road helmets were tested, one each from Giro, Specialized, and Kask. Each is something of a hybrid between a road and time trial helmet, designed to be cool and comfortable and also reduce drag. To complete the spectrum, a Kask Bambino time trial helmet was tested.
As a point of reference, if you switched out the stock aluminum Mavic Cosmic wheels to pricey carbon Zipp 404 Firecrest wheels on a Cervélo S3 aero road bike, WAD is lowered by 65.9 grams. To get those efficiency savings in a helmet swap, a rider would have to switch from the Aeon road helmet to the unvented Kask Bambino time trial helmet. That’s not practical for someone riding on the road; it would be too hot on most days.
In all, the aero road helmets we tested will decrease drag by about one-third to one-half as much as changing to an aerodynamic wheelset. But the price cannot be argued with.
My take from this is if you are looking at a way to reduce aerodynamic drag and money is not a factor - wheels are the way to go.  If you have a limited budget and need a new helmet then switching over to the Specialized Evade ($225.00 MSPR) is a good option.
