The RAVEL loves gravel. The dynamic bars indicate the direction of travel: It goes forward. And when the going gets fast, the gaps ensure good ventilation. If the gravel track is rough, the helmet should fit perfectly. The Ravel's height-adjustable run system guarantees that. In addition, the Gravel helmet is safe, light and comfortable to wear thanks to the Inmold-Tec fabrication. An antibacterial interior ensures that it stays that way. Optionally, the Ravel can be equipped with a flash light. The Ravel is "Made in Germany".
• Very lightweight
• Individually adjustable to the shape of the head with a run system
• Individually adjustable to the shape of the head with a run system
• Strategically arranged ventilation openings guarantee optimal climate control of the interior.
• All Alpina helmets manufactured using the inmold process are fitted with a robust ceramic shell. A polycarbonate plate is stretched under intense heat onto the shape of the helmet in the making and pressed onto the Hi-EPS body under high pressure and thermally bonded to it. The Ceramic shell is characterized by several qualities: It is impact- and scratch-resistant, UV-stable and antistatic.
• The inner shell of all Alpina helmets is made of Hi-EPS (High Expanded Polystyrene). The material has microscopically small air chambers that absorb the forces acting on the helmet in the event of an impact. Hi-EPS provides optimum protection and at the same time allows for extra-thin helmet wall as well as narrow helmet shapes.
• In the inmould production process, the polycarbonate upper shell is thermally bonded to the Hi-EPS inner shell of the helmet body under intense heat and pressure. This creates a large and inseparable connection between the upper and lower shell. Advantage: The helmet is very light and at the same time extremely stable.
• The Run System enables all Alpina helmets to adjust to a custom size by using an easy-to-move dial. The valuable Run System Ergo+ has two large wing-shaped head supports that make it comfortable to wear. The difference from the Run System Ergo Pro: the head supports do not have rubber coating.
