Helmet Rudy Project Boost 01 with 10 ventilation openings and 2 removable front covers for triathlon and time trial. With Fastex System Closure Buckle closure system and RSR 9 Retention System, an ultralight system that has three adjustable height positions to guarantee maximum stability. The RSR 9 Retention System also has a micrometric adjustment system that can also be activated with one hand when it is moving.Characteristics:- Customizable Air ManagementThe Rudy Project Boost 01 is equipped with a set of removable front covers, one closed and one in a mesh configuration, which will allow you to manage the air flow inside the helmet. You will be able to control ventilation and aerodynamic efficiency depending on environmental conditions and maintain the efficiency of your body. The closed configuration offers the best aerodynamic efficiency, but the least ventilation. It is recommended for short / medium competition where time is the most important. The network configuration has a very good compromise between ventilation and aerodynamics. This allows the air to pass through the vents and cool the temperature, while protecting the head against insects. Likewise, it maintains a very good aerodynamic efficiency. The open configuration is the best solution for long distances and for hot weather conditions. Maximum ventilation is definitely necessary to keep the cyclist cool.- Dynamic Pressure PointBy reducing the length of the tail and adding material in the upper part (Dorsal Ridge), the center of pressure of the helmet is moved forward in order to coincide with the center of gravity of the head of the user, obtaining a better Balance of weight and avoiding rotation of the shaft caused by the force of the lateral winds.- Universal Dorsal RidgeInspired by sharks, the dorsal crest of the Boost 01 helps the conversion of lateral forces into a force forward, as if it were a long-tailed helmet.- Zero TorqueMore aerodynamic efficiency, less fatigue. A long-tailed helmet ensures exceptional efficiency in the event of a headwind. In most cases, however, environmental conditions are variable, during long runs against the clock, for example, often the air hits the hull laterally with a candle effect that the larger the surface of the hull in question, the greater it will be the effect. This imposes a number of tensions on the muscles of the neck in order to keep the head in the same position. With optimally dimensioned front and side sections, and the innovative design of the Boost 01, the Boost 01 reduces aerodynamic drag by 12% compared to a traditional road hull, reducing neck twisting efforts by 65% ??and, Therefore, fatigue, which allows to focus totally on sports performance. The Dorsal Ridge effectively deflects the air flow, thereby allowing the athlete to go faster, with less energy consumption.
