HJC Helmet Bicycle RedBull Road Bike Helmet Special Edition [ORACLE RACING/Red Bull/Limited Color/FURION 2.0] (M(55-59cm))

[Features] Weight: 190g (±10g) * Red Bull limited edition color * SELFITT allows for self-adjustment through automatic fitting * Cool air flows around the head for improved comfort while riding * Lightweight model [SELFIT] SELFIT is an automatic adjustment fitting system that is a revolutionary technology in bicycle helmet fitting. Once the helmet fit is set on your head, there is no need to adjust it further even if your head moves while riding. The SELFIT system automatically adjusts the gap to provide a stable fit and comfort to your head. [5 STEP SNAP FIT] Five snap fitting positions provide consistent fit and comfort for all kinds of head shapes and sizes, resulting in a helmet that is ideally adjusted for the perfect ride time after time. [COOLPATH] COOLPATH is a new technology that replaces the inner padding, allowing cool air to flow around your head, improving your comfort while riding. The cool airflow and lightness of the helmet improve the fitting and provide a superior riding experience. [WIND TUNNEL TESTED] HJC helmets are tested in the laboratory as well as in "real life" to meet the highest quality standards. HJC is one of the few helmet companies with its own state-of-the-art wind tunnel laboratory to test aerodynamics, ventilation, noise, and more. The HJC wind tunnel testing lab measures aerodynamic forces in a variety of riding conditions to improve helmet performance. [AERODYNAMIC DESIGN] With experience designing helmets for MotoGP races, HJC designers and engineers have become experts in aerodynamics and well-ventilated helmets. Aero helmets, as the term suggests, are more aerodynamic than traditional racing bike helmets, but at the expense of ventilation. With HJC helmets, this compromise is greatly reduced. HJC offers a semi-aero helmet with perhaps the best ventilation on the market. Save watts with an HJC helmet! [ADVANCED AIR CHANNEL] A certain amount of air passes through the front intake port, circulates inside the helmet, and finally exits through the exhaust port. The internal airflow is increased to cool the head and expel heat. [VENTURY DYNAMICS/MAXIMUM BREATHABILITY] A technical adaptation of Bernoulli's principle has been applied to HJC's aerodynamically enhanced models to achieve maximum ventilation. In operation, the speed of the surface flow generally increases as it travels towards the rear of the helmet. The pressure difference allows cool air from the front intake to be extracted through the rear vents, dissipating the internal heat, providing the cyclist with optimal ventilation and perfect airflow while riding. IN-MOLD CONSTRUCTION: In-mold is a method that consists of gluing EPS to a polycarbonate outer shell for increased structural strength, which improves the rider's protection through compact reinforcement and gives the product a perfect finish. Featherlight: HJC bicycle helmets are designed and engineered with precise measurements to be as light as possible. Density, placement, shape and materials all play a role in optimizing weight.
