air speed iridescent black helmet

More aerodynamic than ever, developed and designed with Astana Pro Team, the Air Speed produced the fastest average speed (40kmph), during the comparative tests carried out in the Magny-Cours wind tunnel in France against competitor helmets of this type. The Air Speed is the fastest helmet in the Air Revolution Range and is used by World Tour Team Astana, UCI UK Continental Pro teams Vitus Pro Cycling, Swift Carbon Pro Cycling, Cams Tifosi Women's Pro Team and GB Triathletes. Studies have proved that about 20% of the aerodynamic drag depends on the bike used during competitions, while the remaining 80% is due to the athlete's position on the saddle. The helmet is therefore the fundamental element to minimise the frontal area and to create a higher level of aerodynamic penetration. Air Speed's aerodynamic and compact design, attractive shape and tapered lines make it a helmet that can be used for all types of road riding. It also includes a magnetic buckle for secure and easy opening and closing. **Extreme Ventilation** The twelve air vents and the three longitudinal channels allow quicker extraction of hot air, granting an immediate and more effective cooling effect on the head, even during longer rides. **Power During the Race** During the latest tests carried out at the Boardman Performance Centre (UK), there was further confirmation that the Air Speed allows the rider a greater saving in watts during performance. * Technology: Monoshell in-mould * Air Vents: 12 air vents, 3 longitudinal inner air flow channels * Sizing System: AirFit-System with height adjustment and webbing connection * Pads: Non-allergenic and washable comfort pads * Fit: Pro * Size: M: 54-58 / L: 57-61 * Weight: M: 250g / L: 270g
