ROOT MIPS, Bike helmet

The height of the Run-System at the back of the head can be adjusted using the 3D-Fit System. The helmet can be perfectly adapted to the head in a five-point gradation system. This improves comfort when wearing, safety and accuracy of fit.

All Alpina helmets manufactured using the inmold process are fitted with a robust ceramic shell. A polycarbonate plate is stretched under intense heat onto the shape of the helmet in the making and pressed onto the Hi-EPS body under high pressure and thermally bonded to it. The Ceramic shell is characterized by several qualities: It is impact- and scratch-resistant, UV-stable and antistatic.

Edge Protect is an additional polycarbonate plate that give inmold helmets a touch of refinement. It covers the edges on the underside of the helmet. This protects the Hi-EPS and increases the helmet's durability.

EPP is a multi-density material that doesn't lose its protective effect even after multiple impacts. The expanded polypropylene (EPP) makes helmets even more robust and durable. EPP is used in helmets like the ALPINA ROOTAGE EVO at strategic points, like the ears and neck area, to guarantee optimal safety.

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 in the event of an impact. Hi-EPS provides optimum protection and at the same time allows for extra-thin helmet wall as well as narrow helmet shapes.

In the inmould production process, the polycarbonate upper shell is thermally bonded to the Hi-EPS inner shell of the helmet body under intense 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.

MIPS is a system that provides protection against brain injuries that can be caused by rotational movements in an impact. The low-friction insert allows it to glide smoothly 10-15 mm in any direction, thus reducing the rotational movement in the event of a fall. This gives MIPS extra protection.

The first adjustment system with integrated MIPS. The RUN SYSTEM ERGO FLEX offers individual, height-adjustable helmet adjustment. This combination not only increases comfort, but also guarantees additional safety in impacts with rotational forces.
