It's the oldest quarter of Oslo. And at the same time the hottest of the city. The name combines tradition and modernity, urban lifestyle and trend awareness. Everything that makes GRUNERLOKKA. With a helmet you wear a feeling on your head. A feeling that arises when you glide with your fixie over the asphalt of your city, around you are bars, cafés, graffiti and green spaces. The GRUNERLOKKA stands for light-heartedness, design, safety in the city. And the fun of life.
To make you feel as comfortable and safe as possible in an urban environment, the GRUNERLOKKA offers well thought-out technologies and a long list of equipment. The low weight ensures optimum wearing comfort. This is achieved by Inmold production, in which the upper shell is thermally connected 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 closure is integrated into the front pad. The best protection in the visible area is thus guaranteed. In addition to vision, the GRUNERLOKKA also focuses on being seen. Thanks to the integrated light, you can also travel safely in the evening. It is built into the Run System Classic with which the helmet can be adapted 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, its clean design and the best possible safety, the GRUNERLOKKA makes you want to take your next tour of the city. In your city. From café to café, from bar to bar, right into life.
Run System Classic
The Run System on all Alpina helmets allows the size of the helmet to be individually adjusted using 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 securely and uncomplicatedly where it belongs: on the head.
A helmet can only provide the best possible protection if it remains in the optimum position in the event of an impact. The adjustment and fixation of the two straps under the ear plays a decisive role. The Y-Clip system guarantees millimetre-precise adjustment - in a matter of seconds.
Proven hundreds of thousands of times and used on all Alpina helmets: the belt buckle with the red push button and multi-stage automatic snap-in mechanism. Ergomatic can be operated with one hand - you can loosen the strap uphill, tighten it downhill - and in the event of a fall it is not possible for the locking mechanism to open automatically.
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, directed along the head and can then flow out again at the rear. The head is therefore always pleasantly air-conditioned.
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 acting on the helmet in the event of an impact. Hi-EPS provides optimum protection and at the same time enables extra-thin wall thicknesses and narrow helmet shapes.
In the Inmold production process, the polycarbonate helmet shell is thermally bonded to the Hi-EPS inner shell of the helmet body under great heat and 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.
All Alpina helmets manufactured using the Inmold process receive a robust Ceramic Shell. A polycarbonate plate is stretched under high heat onto the shape of the later helmet and pressed under high pressure onto the Hi-EPS body and thermally connected to it. The Ceramic Shell is characterized by several qualities: It is break- and scratch-resistant, UV-stable and antistatic.
