The Spatzwear Windsock Pro is a race-ready aero oversock developed to push performance boundaries. It features a newly developed internal gripper system, refined aerodynamic shaping, and a sleek, weather-protective construction for riders who need speed. Developed for maximum efficiency in fast race conditions, the Windsock Pro combines a waterproof stretch main panel with an aerodynamic lycra leg section for a close, stable fit. Wind tunnel testing indicated improved aerodynamic performance over standard wind socks, with consistent CdA reductions across most yaw and speed angles.
The Windsock Pro shares many of the fabrics and features of the legendary Windsock2 but adds a new printed internal gripper. The new vertical grippers are 1mm thick and offer a secure grip on the leg without any extra compression. The grippers can barely be seen or felt whilst in use and they do not alter the fit, feel or function of the overshoe. Their position on the leg means that the faster you ride, the more the grippers adhere to the leg for a no-slip grip.
Testing at the SSE Hub wind tunnel indicated that the Windsock Pro is more aerodynamic than similar products. The results suggest that the Windsock Pro is the optimal choice for riders seeking the best aerodynamic performance in varying wind conditions.
Care Instructions:
Wash with detergent before first use, especially with white shoes. Some colour seepage may occur initially, particularly on matte white shoes, but it is not permanent.
