Lazer's Tardiz is your meticulously engineered advantage against the clock. It boasts a suite of wind-cheating features to help you sail to new personal bests. Lazer's Dual Layer Aerodynamic construction smooths the air to help you knife through the wind and the Tardiz's unique Head-Down design shaves seconds even when you're looking down. For a comfortable fit, Lazer's Rollsys Retention System conforms perfectly to your head and is super easy to adjust. This fast lid also boasts Lazer's handy Aquavent that makes it easy to cool yourself down with water for another competitive edge.

DLA stands for Dual layer Aerodynamics

This means the helmet has multiple surface treatments for optimal aerodynamics. The helmet exists out of 2 parts: a front glossy surface and a back matte dimpled surface. The front smooth glossy surface provides the best possible airflow and the least resistance in the area where the helmet first makes contact with the air. Front vents allow the air to flow through the front part of the helmet and around the head to keep the rider cool. This heated air escapes out of the back vents where the air gets trapped on the matte dimpled surface. This low pressure area helps to pull the cooler air over the front smooth glossy surface of the helmet. At speed, the helmet will actually help pull itself through the air.

Optimal aerodynamics while riding with head down.

Going fast is all about power, technique, and the perfect riding position. Keeping your posture small and your head down are key to having a good aerodynamic position on the bike. Head-down aerodynamics means the helmet will actually improve its performance when your head is down and your riding position is changed to a more aero style. 

The main goal of wearing a helmet is to avoid getting injured. The fitting of a helmet is therefore very important and is essential for safety and comfort. As Lazer is always looking for innovation, we developed the most advanced fitting system to optimize comfort and fit. The Lazer Rollsys system is born…

How does it work?

Compared to the standard fit systems, the Lazer Rollsys system is a fully integrated mechanism which surrounds the head completely. By turning a smooth thumb wheel (situated on top of the helmet rather than the back of the helmet) the Rollsys system permits an accurate and progressive peripheral sizing adjustment. The fit of the helmet will symmetrically be tightened without any pressure points on the head.

The Rollsys system offers an innovative one hand use and is easy to handle even during riding. By taking away the retention system at the back, the Rollsys system is also the perfect solution for people with a ponytail.

Roll into the Future

From the moment the Rollsys system was introduced to the market, it immediately got rewarded for its design and innovation. The testing by thousands of riders proved its efficiency and durability. In other words… plenty of reasons to integrate the Rollsys system in each newly developed helmet.

The adjustable head basket allows the back part of the rollsys system (that grips the back of the head) to move up and down depending on the riders preference. This way the Rollsys system can be adjusted even more to individual rider needs and can create even more comfort.

The Aquavent is a ventilation port on the top surface of the helmet. You can use your bottle to deliver water into the Aquavent to help reduce overheating. Special perforated EVA padding and EVS channeling allows the water to filter down and around the head. Optimal water and air flow over the head provides for maximum cooling and riding efficiency.

Water-based padding for increased cooling and comfort.

The Aquapad is made from a “soft solid” material, that joins together the 3D deformation of a fluid and the memory shape of a solid. The use of the material results in a reduction of pressure concentration (pressure points) on the head, which is beneficial for blood circulation. Additionally, the Aquapad allows a reduction of skin temperature due to its high heat-conducting properties. The reduced skin temperature is desirable as it reduces sweat production. Finally, the Aquapad is shaped such that it prevents sweat droplets, containing salt, from dripping into the eyes which often results in mild pain. 

Perforated helmet padding to distribute water over the head.

The Perfopad helps you cool of when you need to. Just pour water from your bottle through the Aquavent and the Perfopad will make sure the water gets spread over the head. 

Exclusive to the Tardiz helmet, the Perfopad works in combination with the Aquavent to keep your head cool in warm conditions. It is the ultimate combination of TT aerodynamics and road-helmet cooling techniques. 

The Magic buckle allows riders to quickly close or open the buckle connecting the two straps. With one hand the rider just pushes it open or closes it by bringing the male and female part close together— magnetic forces do the rest. Thanks to this solution, the hassle of opening or closing your buckle is now a problem of the past. Even in winter when wearing gloves, riders can easily open and close the buckle without any difficulties. It will also prevent skin from getting in between the lock which is very handy for the under 10 riders.

Lazer helmets are tested in a specifically designed vent tunnel. This test measures the amount of air that is flowing over the head and in which specifc areas. That way we can effectively measure the ventilation a helmet offers. Based on this testing, we adjust the vent position and size of the vents to make sure we create products with good ventilation to make sure you can perform at top level.

All helmets are designed to be safe, but Lazer helmets are also designed to be fast. That is why our helmets are tested in wind tunnel facilities. They go through a varienty of tests to measure the aerodynamic performance and improve it where possible.
