Despite having all the hallmarks of a time trial helmet, Limar’s new Air Atlas UAP (Unidentified Aerial Phenomena) is surprisingly aimed at the road and gravel segments, with the goal of striking a balance between aerodynamics, comfort and optimal ventilation.
“A refined elongation of the rear section designed to promote smoother airflow reconnection around the rider’s head and improve shell stability at high speeds. Inspired by the most efficient forms in nature and engineering, Air Atlas UAP delivers superior aerodynamic performance while maintaining the key features that made Air Atlas iconic: extreme lightness, advanced internal ventilation, and outstanding comfort. The redesigned rear section, developed with aerodynamics at the core of the project, allows for more controlled interaction with airflow, reduces turbulence, and ensures maximum efficiency in racing conditions. Every detail has been validated in the wind tunnel and on the road, delivering tangible benefits without compromising breathability or weight,” says Limar.
Just how aero is the Air Atlas UAP?
According to Limar, during wind tunnel testing, the new lid delivered an improved aerodynamic signature of 0.7 to 1.4 watts at speeds between 40 and 50km/h (24.9-31.1mph), when compared to its Air Speed model.
As mentioned, ventilation played a critical role when developing the Air Atlas UAP, which comprises a series of large air vents along the front and sides, creating a Venturi effect around the helmet.
“With Air Atlas UAP, ventilation is conceived as a continuous airflow that begins with air entering through the large frontal vents and moves inside the shell through a network of specially engineered internal channels, cooling the rider’s head. The Venturi effect generated by the UAP structure positioned at the rear of the helmet allows the internal airflow to be efficiently extracted and rejoin the external flow running along the helmet’s surface. In this way, vortices and turbulence are minimized, transforming airflow into pure speed,” explains Limar.
Elsewhere, the Air Atlas UAP features Limar’s new Air Fit Evo adjustment system and the Fidlock magnetic buckle to ensure a stable, secure and precise helmet fit.
However, perhaps the most standout feature of the Air Atlas UAP is its new removable rear extension that’s designed to further enhance the helmet’s wind-cheating capabilities during events when racing against the clock is critical.
The Air Atlas UAP is available in three sizes, along with four different colorways for €259,95.
