Alpina - Grunerlokka
To make you feel as comfortable and safe as possible in an urban environment, the Grunerlokka has well thought-out technologies and a long list of equipment available. Its low weight ensures optimum comfort. This is due to the Inmold manufacturing process, in which the upper shell is thermally bonded to the Hi-EPS. This results in a firm surface connection, which is responsible for a very stable construction. The Grunerlokka is equipped with a very high quality padding in leather haptics, which ensures a pleasant wearing comfort and underlines the design aspect of the helmet.
At the same time, a textile shield with a discreet reflector finish is worked into the front pad. The best protection in the field of vision is thus guaranteed. In addition to seeing, the Grunerlokka also focuses on seeing. Thanks to the integrated light, you are also safe on the road in the evening. It is installed on the Run System Classic with which the helmet can be adjusted to the individual head size.
The features are completed by the loops on the straps, which can be used to fix headphones. With its details, clean design and the best possible safety, the Grunerlokka makes you want to go on the next tour in the city. In your city. From café to café, from bar to bar, right into life.
Run System Classic With the Run System, the size of all Alpina helmets can be individually adjusted with a smooth-running rotating wheel. The Run System Classic scores with its price/performance ratio. It is a simple and robust adjustment wheel that holds the helmet safely and easily where it belongs: on the head.
Y-Clip A helmet can only provide the best possible protection if it remains in the optimum position in the event of a collision. The adjustment and fixing of the two straps under the ear plays a decisive role in this. The Y-clip system guarantees a millimetre-precise adjustment - in seconds.
Ergomatic Proven hundreds of thousands of times and used in all Alpina helmets: the belt buckle with the red push button and multi-stage automatic lock. Ergomatic can be operated with one hand - uphill you can loosen the strap, downhill you can tighten it - and in the event of a fall, the buckle mechanism cannot open by itself.
Airflow Vents One factor that strongly influences the wearing comfort is the ventilation of the helmet. The strategically sensible arrangement of the ventilation openings is decisive for optimum ventilation of the interior. The air is directed into the interior, where it is guided along the head and can flow out again at the rear. The head is thus always pleasantly air-conditioned.
HI-EPS The inner shell of all Alpina helmets is made of Hi-EPS (High Expanded Polystyrene). The material has microscopically small air chambers which absorb the forces that act on the helmet during an impact. Hi-EPS provides optimum protection and at the same time allows extra-thin wall thicknesses and narrow helmet shapes.
inmold In the Inmold production process, the helmet upper shell made of polycarbonate is thermally bonded to the Hi-EPS inner shell of the helmet body under great heat and strong pressure. This creates a large-area and inseparable connection between the upper and lower shell. Advantage: The helmet is very light and at the same time extremely stable.
Ceramic Shell All helmets from Alpina, which are manufactured using the Inmold process, are equipped with a robust ceramic shell. A polycarbonate plate is stretched under high heat onto the shape of the future helmet and pressed with high pressure onto the Hi-EPS body and thermally bonded to it. The Ceramic Shell is characterized by several qualities: It is break and scratch resistant, UV-stable and antistatic.
