While we always do our best to provide an objective and unbiased review of the best bike kits on the planet, it's often hard to add objectivity with things like aero helmets. You will often see something like "This helmet feels fast", which is hard to prove and easy to dismiss.

To avoid that, we spent a lot of money on some commercial wind tunnel time and Josh, associate editor of all the most Cyclingnews on the market to determine the very best aerodynamic helmet, was the fastest, not only in straight lines, but also in a full sweep of the yaw angle (the angle at which the wind is hitting you). I spent a lot of time deep into the aero calculations to solve what I had found.

With this data, we could objectively say that the POC Procen Air is the fastest helmet on the market, but this is not a big surprise as it is effectively a time trial helmet. The fastest "normal" helmet was a special avoidance 3, which was faster than Procen without a visor. 

The good news is that we've found both of these helmets on offer for Black Friday, so the watt/$ ratio will only get better. Head to our Black Friday Bike deals hub for more handpicked deals.
