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) ●Limited Red Bull color ●SELFITT enables self-adjustment through automatic fitting ●Flows cool air around the head to improve comfort while riding ●Lightweight model [SELFIT] SELFIT is a self-adjusting fitting system that is an innovative technology in bicycle helmet fitting. Once the fit of the helmet is set on your head, no further adjustments are necessary even if your head moves while riding. SELFIT system automatically adjusts the gap to provide a stable fit and comfort on the head. 【5 STEP SNAP FIT】 5 snap fitting positions provide consistent fit and comfort for all types of head shapes and sizes, resulting in a helmet that is ideally adjusted for the perfect ride time and time again. [COOLPATH] COOLPATH is a new technology that replaces inner padding, allowing cool air to flow around your head for increased comfort while riding. Cool airflow and the lightness of the helmet enhance the fit and provide a superior riding experience. 【WIND TUNNEL TESTED/WIND TUNNEL TESTED】HJC helmets are tested not only in the laboratory but also 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 for testing aerodynamics, breathability, noise, and more. The HJC Wind Tunnel Test Lab measures aero forces in a variety of riding conditions to improve helmet performance. [AERODYNAMIC DESIGN/AERODYNAMIC DESIGN] From MotoGP race helmet design experience, 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 the HJC helmet, this compromise is greatly reduced. HJC offers perhaps the best vented semi-aero helmet on the market. Save Watts with HJC Helmets! [ADVANCED AIR CHANNEL/ADVANCED AIR CHANNEL SYSTEM] A certain amount of air passes through the front intake port, circulates inside the helmet, and finally exits through the exhaust port. Increased internal airflow cools the head and removes heat. VENTURY DYNAMICS/MAXIMUM BREATHABILITY To achieve maximum breathability, a technical adaptation of Bernoulli's principle is applied to HJC's aerodynamically enhanced models. During operation, the velocity of the surface flow generally increases as it progresses toward the rear of the helmet. Due to the pressure difference, cool air from the front intake is extracted from the rear vent, dissipating 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 to increase structural strength. This provides better protection for the rider through compact reinforcement and gives the product a perfect finish. [Feather Light] HJC bicycle helmets are designed and engineered through precise measurements to be as lightweight as possible. Density, placement, shape, and material all play a role in weight optimization. [The long-awaited second edition of the ORACLE RedBull RACING model! ]
