Smith Overtake Road Bicycle Helmet. No other Bicycle Helmet has garnered so much attention and anticipation as the release of the Overtake. And for good reason. The Smith Overtake Road Bicycle Helmet delivers incredible performance thanks to its unique design and technology. By providing maximum ventilation, superior aerodynamics and improved protection, the Overtake is the ultimate racing Bicycle Helmet and a must have for any cyclist, in any event. Smith integrates their proprietary technologies with best in class protection options, their AEROCORE construction featuring Koroyd and MIPS optional linings. These features make the Overtake your ticket to the podium. Smith's objective and design philosophy behind AEROCORE construction is to increase airflow, improve temperature regulation resulting in fog free vision and improve impact resistance. The objective was achieved through the combination of materials such as EPS and Koroyd, a revolutionary new material that absorbs more energy upon impact when compared to international standards, while increasing airflow. AEROCORE construction through the use of Koroyd and EPS allows for more vents to be placed throughout the Bicycle Helmet without sacrificing protection and comfort. About MIPS: MIPS is used to reduce the rotational forces to the brain in the case of an oblique impact. Smith helmets are created to absorb direct impacts very efficiently and when combined with MIPS, Smith helmets absorb oblique forces better by allowing a small rotation of the outer shell relative to the liner. When you fall to the ground at an angle rotational forces are generated. A Bicycle Helmet integrating MIPS technology creates a sliding layer between the outer shell and the head. This allows the Bicycle Helmet's outer shell to slide relative to the head when hitting the ground, so the rotational force is decreased, reducing the potential to damage your brain.
