【Item History】 This helmet was used by my son, who was a member of the cycling club (specializing in track sprints) in high school. It is being sold due to his retirement. He is 167cm tall and weighs 65kg, and used a size M. Used in about 20 races. There have been no falls or impacts. For those seriously involved in competitions such as 1km TT, sprint (flying 200m), and triathlon, how about this valuable White color M size to improve your competitive performance?

It achieves a high reduction in air resistance and improves the performance of athletes. 【Design and Features】 In addition to the sophisticated silver design, the full-face shield ensures visibility and minimizes the effects of wind. It also has adjustment functions that support multiple head positions, providing a comfortable fit. World-standard short-tail aero helmet Optimizes aero effects in multiple positions while maintaining aerodynamic characteristics from all angles. Developed and tested in the wind tunnel facilities of the Milan Polytechnic University and the Milan Newton Lab, the "CODATRONCA" has a wide shell shape that efficiently guides the flow of air towards the rider's shoulders and back, suppressing the generation of turbulent airflow that creates resistance, thereby demonstrating excellent aerodynamics. The standard-equipped shield not only provides good visibility but is also easy to attach and detach with magnets.
