The Thunder 2.0 helmet by Alpina - light and safe

The Alpina Thunder 2.0 helmet is the ideal helmet for all applications in off-road and everyday use.
It is equipped with a break-proof polycarbonate shell, connected to the inner shell made of Hi-EPS by an in-mould process. Alpina's Run-System Classic ensures a secure fit and maximum wearing comfort.
The 25 ventilation openings, protected at the front with fly nets, provide the head with fresh air during the ride, the Edge Protect edge refinement protects the bike helmet from rough or pointed objects when taking off and makes it particularly durable.


Application: All Mountain, City & Touring
Air Circulation Vents: 25
Construction: in-mould


In-Mold Tec
In the in-mould production process, the polycarbonate helmet shell is " baked" with the EPS granulate of the helmet body under great 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.

Ceramic Shell
All Alpina in-mould helmets are fitted with this break-resistant and scratch-resistant polycarbonate shell. The blank is stretched under strong heat onto the shape of the later helmet and pressed with high pressure onto its Hi-EPS body. The material is characterised by several qualities at the same time: It is break-resistant, scratch-resistant, UV-stable and antistatic.

The inner shell of every Alpina helmet is made of Hi-EPS (" High Expanded Polystyrene" ). It consists of microscopically small air chambers which optimally absorb the forces acting in the event of an impact. Hi-EPS ensures extra-thin wall thicknesses and narrow helmet shapes in spite of optimum protection.

Run System Classic
The Run System allows the size of all Alpina helmets 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.

Custom Fit
Custom Fit is an adjustment system at the back of the head that allows you to adjust the height of the Run System in several stages. This allows the optimum fit of the helmet to be adjusted for a wide variety of head shapes. Pressure points are a thing of the past, the helmet fits perfectly and safety is increased.

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, directed along the head and can then flow out again at the rear. The head is therefore always pleasantly air-conditioned.

Edge Protect
Edge Protect is a processing technique that ensures that in-mould helmets have no sharp edges. This reduces the risk of injury in two ways: On the one hand, the hands are spared when handling the helmet, on the other hand, the neck and shoulder area is protected from scratches in the event of a collision with the lower edge of the helmet.

Shield Protect
The removable shield protects the face both from splashing dirt and from direct sunlight.

Fly Net
The front ventilation openings of the helmet are provided with a net fabric. This has the same function as an insect screen and prevents insect bites on the scalp in hot and humid riding periods and places.

A helmet can only protect well as long as it remains in the optimal position during an impact. The fixation of the two straps under the ear plays a decisive role. The Alpina Y-Clip system guarantees millimetre-accurate 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 - uphill the strap can be loosened, downhill it can be tightened - and in the event of a fall it is not possible for the locking mechanism to open automatically.
