The HJC Furion 2.0 is a beautifully finished semi-aero bike helmet designed for triathlons and sportives. Made by South Korean company HJC, this updated aerodynamic helmet offers a 7% energy saving advantage over competitors. With several WorldTour victories under its belt, it is a popular choice for teams such as AG2R Citroën and Israel Start-Up Nation. Aerodynamic helmets often compromise on weight and airflow, but the compact Furion 2.0 minimizes these compromises. Weighing just 190g, it is 10g lighter than HJC's other pro-level helmet, the Ibex. The Furion 2.0 has a progressive design, tested and refined at HJC's bespoke wind tunnel facility. It combines maximal streamlining with ventilation to provide optimal airflow. The innovative CoolPath construction eliminates the risk of insufficient cooling in an aero helmet. Without traditional pads, CoolPath cradles your head in a way that allows air to flow from the front to the rear, keeping you cool even during prolonged effort. In contrast to other aero helmets, the Furion 2.0 maintains a clean-cut aesthetic without unnecessary distractions. It features an extra-wide gap at the rear, suitable for longer hair or ponytails, and a 55 degree chin strap angle to prevent twisting. The Furion 2.0 has an intelligent fitting system based on comprehensive 3D analysis of different head shapes. HJC's Selfit helmet adjustment system replaces the traditional dial with an ergonomic snap fit adjuster. It pivots within the helmet as you move position, ensuring maximum protection and comfortable fit in any riding position. Sizing is straightforward, just measure your brow circumference and adjust the helmet accordingly. Key features of the HJC Furion 2.0 include unrivalled aerodynamic capabilities, an innovative CoolPath ventilation system, and a weight of only 190g. It also has an easy-to-adjust fitting system based on 3D analysis for lasting comfort. Sizing options are as follows:- Small: 51-56cm- Medium: 55-59cm- Large: 58-63cm
