If you are after a full aero road helmet, then search no further. The Ballista has reset our expectations of aero road helmets. Bontrager was relatively late to the aero helmet party, with many manufacturers releasing aero models a year or two before the Ballista release. The Ballista is the first aero helmet in the Bontrager lineup, and it does not disappoint. As the aero sub-category has grown, almost every manufacturer has come out with a helmet and claims of superior aerodynamics over the competition.
Do aero road helmets make you faster? In the right conditions, the answer is yes. We do not have a wind tunnel to verify manufacturer claims, but it is likely that the shape of aero road helmets does reduce drag to some extent. Nearly every manufacturer claims that their helmet is fastest. The data that is released is more often than not quite vague with claims such as "9 watts faster than the competition". We recommend that you take these claims with a grain of salt, and look at other factors such as comfort, ventilation, and adjustability when selecting an aero helmet.
The Ballista could be the fastest helmet on the market, or maybe not. We awarded it our Top Pick award for Aero Helmets based on superior comfort and ventilation as compared to other aero road helmets we have tested. This also comes in a MIPS version for an extra $25.
