Alpina Brooklyn Cycling Helmet Mat Black/Yellow - 57-61 cm

These are the ingredients for an urban helmet. The ALPINA BROOKLYN is a helmet designed for the city.
While the design language of the ALPINA BROOKLYN is understated, it stands out.
Asymmetrical air inlets on the forehead, matte solid colors, a short visor, large ventilation openings on top, which form a protective angel with the padding on the inside - and an LED light at the back.
With the push of a button, this provides a light chain around, permanent light, or flashing light, ensuring extra safety in the urban jungle.
To ensure that the Alpina Brooklyn fits perfectly to the head, the Run System Ergo Flex + is integrated.
The size can be adjusted almost continuously using a dial for fine-tuning.
The bicycle helmet is manufactured using the inmould process, where the Hi-EPS inner shell is foamed under high pressure and heat beneath the outer shell.
The result is a lightweight and safe helmet - for a comfortable ride through the city.

AIRFLOW VENTING
A factor that greatly influences wearing comfort is the ventilation of the helmet.
The strategically calculated placement of the ventilation openings is crucial for optimal ventilation of the interior.
Air is directed inside, flows along the head, and can exit at the back.
The head is thus always pleasantly climate-controlled.

CERAMIC SHELL
All Alpina helmets manufactured using the inmould process feature a robust ceramic shell. In this process, a polycarbonate sheet is stretched under high heat to the shape of the future helmet, pressed under high pressure onto the Hi-EPS body, and thermally bonded to the helmet.
The Ceramic Shell is characterized by various qualities: it is break and scratch-resistant, UV-stable, and antistatic.

CUSTOM FIT
Custom Fit The Run System is an adjustment system at the back of the head that allows the height of the Run System to be adjusted in several steps.
This enables the helmet to be optimized for a wide variety of head shapes.
Pressure points are a thing of the past, the helmet fits perfectly, and safety is increased.

ERGOMATIC
Tested and used hundreds of thousands of times on all Alpina helmets: the buckle with the red push button and the multi-stage automatic locking mechanism.
Ergomatic can be operated with one hand - you can loosen the strap uphill, fasten it downhill - and in the event of a fall, it is impossible for the locking mechanism to open by itself.

HI-EPS
The inner shell of all Alpina helmets is made of Hi-EPS (High Expanded Polystyrene).
The material has microscopically small air chambers that absorb the forces acting on the helmet during a collision.
Hi-EPS provides optimal protection while allowing for extra thin wall thicknesses and narrow helmet shapes.

INMOLD
In the inmould production process, the polycarbonate outer shell of the helmet is thermally bonded under high heat and pressure to the Hi-EPS inner shell of the helmet body.
This creates a large and inseparable bond between the upper and lower shells.
Advantage: the helmet is very light and at the same time extremely stable.

RUN SYSTEM ERGO+
The size of all Alpina helmets can be individually adjusted via the Run System using a smoothly rotating dial.
The high-quality Run System Ergo+ features two large wing-shaped head supports that provide high comfort.
The difference from the Run System Ergo Pro: the head supports are not rubber-coated.

Y-CLIP
A helmet can only provide the best possible protection if it remains in the optimal position during a collision.
The adjustment and attachment of the two straps under the ear play a decisive role in this.
The Y-clip system guarantees millimeter-precise adjustment - in just a few seconds.
