Did you already know? There's a new helmet for you in April! Or four of them. Because Fizik has introduced new bike helmets. They are each tailored to specific riding styles and needs. The Kudo-helmet, probably the lightest and best ventilated helmet in the Fizik range, is made for racers - from road to XC MTB. The Kudo Aero helmet offers similar features with an additional focus on aerodynamic efficiency. For pure e-bike and MTB enthusiasts, the Kassis-Helmet with increased ventilation and special protection at the back and sides of the head, including visor.

Finally, the Fizik Kunee completes the range as the most aerodynamic helmet for time trials and triathlons, with optimised shapes for airflow and two removable magnetic visors. Like the other models, it features the MIPS system and lightweight padding for excellent thermal regulation. In addition, all bike helmets - with the exception of the Kunee - have an in-built reflector at the back of the head, which can also be replaced by an optional LED light.

Fizik Kassis

The Fizik Kassis is the new model for demanding trail and mountain bike tours. According to the manufacturer, the Kassis is a lightweight and well-ventilated helmet that offers maximum protection thanks to its robust construction and extended coverage. A key safety feature is the MIPS Air Node System, which is designed to reduce rotational forces in the event of a fall.

The helmet shell of the Kassi is lower compared to classic XC helmets. Despite the additional protection in the temple and neck area, Fizik claims to have focussed on a compact and lightweight design. The in-mould construction made of EPS foam and polycarbonate outer shell is intended to ensure high stability and low weight. A polymer reinforcement bridge inside the helmet effectively distributes the forces occurring in the event of an impact across the entire helmet structure.

MIPS Air Node System for improved impact protection

Fizik has integrated the MIPS Air Node System into the Kassis MTB helmet as a key safety feature. This is a low-friction sliding layer incorporated into the padding. In the event of an impact, this layer is designed to reduce rotational forces that can act on the brain. According to Fizik, the MIPS system is seamlessly integrated into the interior of the helmet without compromising comfort. The manufacturer promises that this technology will provide improved protection against concussion and other head injuries in the event of a fall.

Focus on ventilation and comfort

Despite the robust construction and extended cover, Fizik has placed great emphasis on effective ventilation for the Kassis. Numerous air inlets at the front and large outlets at the rear are intended to ensure a constant flow of air. A particularly wide outlet opening in the neck area additionally supports heat dissipation. This ventilation architecture keeps the head cool even during strenuous climbs and high temperatures.

Fizik equips the Kassis with a multi-stage adjustment system for customised adjustment to different head shapes. The width can be precisely adjusted using a rotary wheel at the back of the head. In addition, the height position of the adjustment system at the back of the head can be adjusted in several stages. This enables optimum positioning, even in combination with glasses or goggles. The straps around the ears are made from lightweight ripstop fabric and their position can also be adjusted.

Integrated LED rear light & visor

As an additional safety feature, Fizik has integrated a reflector at the back of the head. This means that mountain bikers remain clearly visible to other road users even in poor visibility conditions or at dusk. An optional detachable LED rear light for the Kassis bike helmet is available for 25 euros. The USB-chargeable light has different light modes for day and night.

The removable, adjustable visor protects against mud, sun glare and obstacles such as branches. For added convenience, Kassis also offers secure goggle storage, which is integrated into the rear ventilation openings and keeps the goggles stable and easily accessible.

With the Kudo model, Italian manufacturer Fizik presents a new half-shell helmet for use on road bikes, gravel and cross-country routes. This racing helmet focusses on ventilation and weight reduction to ensure optimum comfort even during intense efforts and high temperatures. At the same time, the Kudo fulfils the current EU and CPSC safety standards.

Ventilation and aerodynamics

The design of the Fizik Kudo bike helmet is characterised by a slim, round profile with integrated ventilation openings. The fast version of the MTB helmet, so to speak. This design is intended to minimise air resistance and at the same time ensure effective cooling. The Fizik helmet is particularly strong on long climbs and high performance.

Equipment and customisation

For impact protection, Fizik also uses an in-mould construction made of EPS foam and a polycarbonate outer shell for the Kudo - as with the other models shown here. As a central safety feature, Fizik has also integrated the MIPS Air Node System into the helmet. The helmets do not differ in terms of the adjustment system for adapting to the individual head shape. Last but not least, the optional rear light or reflector is also provided.

Go even faster with the Fizik Kudo Aero - the performance cycling helmet designed for high-speed road, gravel and XC riding and racing. It also offers a fully adjustable fit, integrated light, improved ventilation and the MIPS Air Node System.

Aerodynamic design with rear spoiler

Smooth upper surface without air intakes on the helmet roof and a spoiler improve the air flow and thus reduce air resistance. Despite its aerodynamic focus, the Kudo Aero is in no way inferior in terms of comfort. Two front ventilation slits and rear heat exchange openings ensure efficient thermoregulation and keep the head cool during intense efforts. The helmet is certified to both EU and CPSC standards and its rounded shape is designed to reduce surface drag in the event of an impact.

Fizik Kunee

Fizik's fourth innovation is the Kunee - the helmet for time trials and triathlons. The even more aerodynamic design with a smooth surface, teardrop shape and integrated side plates is intended to reduce air resistance even further. A wide, seamless visor and a ventilation system promise good visibility and cooling. According to Fizik, the helmet is designed to help athletes ride faster and longer.

Minimised air resistance

The design of the Fizik Kunee is based on years of research in the field of dynamics (CFD). The computer simulations were supplemented by tests in the wind tunnel and under real conditions. Fizik claims, for example, that the minimised frontal area further reduces air resistance. The droplet shape adapts to the shape of the body.

A special feature of the Kunee are the corrugated side plates. Unlike many aero helmets, which are wider to cover the rider's shoulders, the Kunee uses these special plates to keep turbulent air close to the helmet. This is intended to allow a smoother transition of airflow around the shoulders and to the rider's back without increasing the overall volume of the helmet.

Visor and ventilation for visibility and comfort

The Kunee's visor extends over the sides of the helmet and is designed to improve both frontal and peripheral vision. It can be attached quickly with magnets. Even when the visor is removed, the helmet should remain aerodynamically efficient when worn with normal sunglasses, for example.

Fizik has integrated a special system above the visor for ventilation. A honeycomb-shaped grid is designed to optimise cooling and reduce air friction at the same time. Fizik claims that this balanced airflow system improves both comfort and performance in aggressive riding positions. In addition, designed low-pressure areas on the sides should reduce wind noise, which should contribute to greater comfort and concentration.
