Product Description
Air Speed Helmet by Limar
Perhaps you noticed a new aero lid atop some of the riders on Team Astana and Direct Energie at this past year's Tour. That was the Air Speed Helmet from Limar and one we'll go on record saying is one of the better looking aerodynamic helmets going. Sure, we all know that aero equates to faster speeds with less effort, however, we certainly value ventilation, style, and a lightweight build as well, and we're happy to report that the Air Speed checks off all of those boxes. Limar developed the helmet in conjunction with Team Astana and during its own testing at a wind tunnel in Magny-Cours, France, it was the fastest helmet of the group at speeds of 40 km/h, and the drag numbers were very close to that of its TT specific helmet, the Air King. We feel this is pretty important as research shows that 20% of aero drag comes from the bicycle, think the frameset and wheels, while the other 80% is from the cyclist position and ancillary items such as shoes, clothing, and the helmet. Therefore, the helmet is critical in reducing the frontal area and thus creating a more aero profile. And because cycling is so dynamic, Limar performed three-dimensional simulations using CFD software while creating the shape of the Air Speed's shell to better replicate the cyclist's head position over the course of the ride rather than one static position all without neglecting the need for ventilation and a low weight. That cooling comes courtesy of 7 vents in the front and 5 vents in the rear joined by 3 longitudinal channels running the length of the helmet. This allows cool air to rush over the head, keeping you cooler while hotter air easily exhausts. Keeping the helmet secure is Limar's Air Fit System offering both vertical and horizontal adjustments for quick and easy fitting. Inside, the soft, washable, and anti-bacterial padding soaks up sweat and prevents any pressure points from interfering with your ride.
