The Grunerlokka Helmet
It is the oldest part of Oslo. And at the same time the most popular of the city. The name combines tradition and modernity, urban lifestyle and trend awareness. Everything that makes up the 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, security in the city. And the fun of life. Thanks to the integrated light, you can also travel safely in the evening.
Alpina Grunerlokka technologies:
Note: Please measure the head circumference to get the right helmet size.
Alpina helmets have inner shells made of Hi-EPS (highly expanded polystyrene). This material consists of many microscopically small air chambers which effectively absorb the forces caused by an impact. Hi-EPS provides optimum protection with the benefit of allowing extra-thin walls.
This impact- and scratch-resistant polycarbonate shell is fitted to all Alpina helmets manufactured using the Inmold procedure. The blank workpieces are shaped at high temperature onto the form of the helmet design and the shells are then pressed onto the helmet's Hi-EPS body. The material combines a number of distinct advantages: it is impact- and scratch-resistant, it contains UV stabilisers and is anti-static.
The removable slide-in visor protects the face both from splashing mud and from solar radiation.
The Inmold production process involves the polycarbonate outer shell of the helmet being heated to a high temperature and "baked" onto the EPS helmet body at high pressure. This produces a permanent bond across the entire surface of the inner and outer shells, producing a helmet with the advantage of being very light yet extremely stable.
RUN SYSTEM ERGO CLASSIC
If you just want to go shopping by bike, you don't necessarily need a complex and expensive fitting system. This is where our Run System Classic comes in: a simple and robust adjustment wheel that holds the helmet securely and uncomplicatedly where it belongs: on your head.
Tried and tested countless times, this is the buckle used in all Alpina cycle helmets. It features a red push button and multi-step automatic adjustment. It can be used one-handed, so for example you can loosen the strap when riding uphill and tighten it again for the descent, and it cannot come open in the event of a crash.
A helmet can only provide proper protection if it stays securely in place in the event of an impact. The fastening that joins the two straps under the ear is critical to this. Alpina's Y-Clip system guarantees a perfect fit down to the last millimetre, all in a matter of seconds.
