Limar launches the aerodynamic Air Atlas UAP bike helmet with removable UAP rear spoiler. Other features include the Air Fit Evo adjustment system and a Fidlock magnetic fastener. The UAP rear spoiler is designed to direct the airflow around the rider's head and improve stability at high speeds. The aero helmet is designed for road bikes and fast gravel rides and will go on sale at the end of March.

The Italian manufacturer Limar further developed the Air Atlas UAP from the existing Air Atlas shell. The company analysed the helmet's behaviour in the airflow at various speeds and usage scenarios. The development department focussed on the aerodynamics and the ventilation system. The UAP attachment is removable.

Assessment by the editorial team

The first question that comes to mind is: Does that make sense? Don't you always want to be aero? At the same time, by removing the rear spoiler, you can turn the extravagant helmet into one that attracts less attention. The FidLock magnetic fastener is practical and can also be operated easily with one hand.

Rear attachment and adjustment system

According to the manufacturer, the UAP extension is designed to control the airflow at the back of the head and reduce turbulence. Limar tested the design in the wind tunnel and on the road. The Air Fit Evo adjustment system is located inside the helmet, while the Fidlock magnetic fastener replaces the classic click fastener. The helmet is based on the Air Atlas UFO shape, which Limar had already developed for ventilation and comfort.

Special edition for gravel team

The Air Atlas UAP x Reverb is being released as a special edition alongside the standard model. Its colour finish is based on the design of the team clothing and features dynamic lines across the entire surface of the helmet. The pattern represents sound waves and combines technical performance with the team identity. Both versions will be available from the end of March 2026.
