The Ventral SPIN sets a new benchmark for aerodynamic performance, safety and ventilation in a road bike helmet.

Aerodynamic performance, safety and ventilation do not need to come at the expense of each other.

By using our whole-helmet approach to development, they have been able to deliver unparalleled levels of aerodynamic performance, safety and ventilation without compromise in the Ventral SPIN. Taking inspiration from the Venturi effect, the helmet’s airflow zones allow the helmet to pass through the air with greater efficiency, making it faster. Residual air traveling around the helmet is managed by the 22° aero trailing edge, the perfect angle for minimizing turbulence, further improving aerodynamic performance. By leading air through rather than around the helmet, its wake is minimized, while its ventilation and cooling properties are enhanced. Other features of their whole-helmet approach include a fully wrapped unibody shell with an EPS liner for the ideal balance between weight and protection. SPIN (Shearing Pad INside), our patent-pending silicone pad technology; a lightweight adjustment system and an ergonomic precision strap provides a flexible, comfortable and secure fit.

Size Guide

Helmet sizes are based on the circumference of your head. To determine the correct size, wrap a measuring tape around your head. Once you've determined the measurement, you can use the chart here as a guide.

Size Small (cm) Medium (cm) Large
Head Circumference 50-56 54-59 56-61
