Alpina Ravel Helmet, czarny

The RAVEL loves gravel. The dynamic bars indicate the direction of travel: It goes forward. And when it gets fast, the gaps provide good ventilation. If the gravel road is rough, the helmet should fit perfectly. Due to the height-adjustable run system of the Ravel, this is guaranteed. In addition, the Gravel helmet is safe, lightweight and comfortable to wear thanks to the Inmold-Tec manufacturing. 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".

Run System Ergo+
With the Run System, the size of the helmet can be individually adjusted on all Alpina helmets via a smooth-running rotary wheel. The high-quality Run System Ergo+ has two large wing-shaped headrests that ensure high wearing comfort. The difference to the Run System Ergo Pro: the headrests are not rubberized.

Hi-EPS
The inner shell of all helmets from Alpina is made of Hi-EPS (High Expanded Polystyrene). The material has microscopic air chambers that absorb the forces acting on the helmet during an impact. Hi-EPS ensures optimum protection while allowing extra-thin wall thicknesses and narrow helmet shapes.

Ceramic Shell
All helmets from Alpina that are manufactured using the Inmold process are given a robust Ceramic Shell. In this process, a polycarbonate plate is stretched under high heat to the shape of the subsequent helmet and pressed onto the Hi-EPS body at high pressure and thermally bonded to it. The Ceramic Shell is characterized by several qualities: It is break- and scratch-resistant, UV-stable and antistatic.
