Ideal For

The trial, Triathlon

Plasmato dal vento.

Engineered for

real-world aerodynamics.

Alien was developed through CFD simulations and extensive wind-tunnel testing, followed by validation in realistic racing scenarios.
Testing included variable wind angles between 5° and 10°, reproducing the crosswinds commonly encountered during road time trials and triathlon events. This approach allowed Limar to optimize the helmet not only for ideal laboratory conditions, but also for the dynamic position and movement of the rider on the road.

Airflow shaped

around the rider.

Alien’s upper shell is divided into lateral and central aerodynamic areas. The side surfaces generate an Outwash effect that redirects incoming air away from the rider’s shoulders.
The central profile uses the Coandă effect to maintain a more controlled airflow along the rider’s back. Working together with the lower shell, these surfaces help reduce turbulence between the helmet, neck and shoulders, improving the aerodynamic efficiency of the complete rider–helmet system.

Efficiency when

every second matters.

The aerodynamic double-shell architecture guides airflow around the rider while three front vents and six internal longitudinal channels support ventilation during sustained high-intensity efforts.
Compared with its predecessor, Air King Evo, testing indicates a significant reduction in aerodynamic resistance, helping the rider maintain race speed with less energy expenditure. Alien is designed for athletes who need performance that remains effective across changing wind conditions, body positions and race environments.
Non inserirei direttamente nel testo commerciale il vantaggio di circa 10 watt finché non sono confermati velocità, posizione, angolo del vento e protocollo di confronto.

What to keep in mind when purchasing a helmet?

All helmets must comply with the safety standards of your own country. The European standard is CE EN 1078. So first of all carefully check that the helmet has the correct label. Then make sure it fits perfectly to your head (not too tight and not too loose). This means you have to wear it properly (which is not usually possible if the helmet is blistered as it might happen when displayed in supermarkets).

What is the helmet efficacy

The helmet is not your ‘life insurance policy’ but international researches have pointed out that it has a variable protection effect. Knowing whether helmets reduce the risk of head injuries by 88%, by 65% or by 50% (just to quote some data) is just important for statistics purposes and a secondary factor if we talk about prevention. The most important aspect is that helmets reduce the risk of head injuries!

Do I need to replace a helmet after an impact

Yes every time during a fall the helmet has suffered a strong shock, even if it does not look damaged. Each impact damages the material the helmet is made of, and your helmet cannot guarantee the same level of protection any more.
