The PIKIO Si is a premium road and gravel cycling helmet from PIKIO Labs, designed to combine advanced impact protection, lightweight comfort, and ventilation. It features OBLIK impact management technology and is ranked #1 by Virginia Tech Helmet Ratings.

The PIKIO Si is designed to provide exceptional protection without compromising comfort, ventilation, or weight. It features OBLIK technology, a modular system designed to help manage impact forces, while its lightweight design and 17 vents keep you cool and comfortable on every ride.

The PIKIO Si is also ranked #1 by Virginia Tech Helmet Ratings, with the highest score among helmets tested by the lab.

It is recommended to replace your helmet every 3 years, even if it hasn’t been involved in a crash. If you've had a fall or the helmet has taken any impact, it's important to replace it right away. Even if there's no visible damage, the materials inside may no longer provide proper protection.

Carefully, attach the modular piece snap pins to their retainers.

Use a soft cloth or sponge with mild soap and warm water to clean only the outer shell of the helmet. Avoid removing the modular pieces or applying any cleaning agents to the EPS components. Do not use harsh chemicals or submerge the helmet in water. The fabric fitting pads can be removed, gently hand-washed, and air-dried before reattaching.

If requirements are met, we will provide you with a new helmet at a discounted rate through our crash replacement program.

Yes, the helmet includes a one-year limited warranty that covers manufacturing defects in materials or workmanship. The warranty does not cover damage caused by accidents, misuse, or regular wear and tear. For more information please refer to our warranty page

No. Any modification or replacement of components will affect performance and void the warranty.

Macro-cavities are engineered voids integrated into the liner structure. They improve shock absorption while reducing material usage and overall helmet weight. When combined with the modular system, helmet ventilation also improves thanks to continuous, deep airflow channels throughout the helmet.

The PIKIO Si is designed with an intermediate oval fit, the most common head shape among cyclists. It is slightly longer from front to back than it is wide, offering a secure and comfortable fit for the most riders.

A properly fitted helmet should feel snug all around your head—not loose and not uncomfortably tight. Shake your head; if the helmet moves independently, it’s too big. Move the helmet with your hand; your scalp should move with it. Buckle the chin strap so it’s secure. Use the adjustment system for fine-tuning.

If your head circumference falls at the upper end of a helmet's size range, we generally recommend sizing up for a more comfortable fit.

All you need is cardboard, a ruler, and a pair of scissors.

At this time, the PIKIO Si is available for purchase online only. We’re working toward expanding our retail presence so riders can try the helmet on in person.

If your helmet feels slightly too big or too small, you can fine-tune the fit using the rear fit system and chin straps. The helmet should sit level and securely on your head without feeling overly tight or creating pressure points.

To adjust the fit system, feel free to check out our video guide here.

The chin strap should be snug but comfortable. Once fastened, you should be able to fit two fingers between your chin and the strap. The helmet should remain securely in place without feeling restrictive or causing discomfort.

You can easily adjust the chin straps at home. Please follow the video guide below for step-by-step instructions.

OBLIK™ is PIKIO LABS’ proprietary helmet impact-management technology designed to manage both linear and rotational forces during an impact. It uses a modular, dual-layer layer, dual-density structure that combines a base liner with independently moving shock-absorbing modules to better absorb and divert energy of impacts coming from any direction. 

You can find our full explanation here: OBLIK .

Traditional helmets rely on a single foam liner, sometimes paired with a slip layer, which can limit how complex impacts are managed. OBLIK™ uses a modular architecture with independently moving elements connected through a deflection-sensitive nodal system. This allows the helmet structure to respond more adaptively to the intensity, location, and direction of impact forces, helping manage both linear and oblique impacts.

Scientific research shows that both linear and rotational forces contribute to head injury risk. Conventional helmets are primarily optimized for linear impacts. OBLIK tries to tackle this limitation by reducing linear and rotational forces during impact without adding weight or compromising ventilation. 

OBLIK consists of a base liner, independently mounted shock-absorbing modules, and flexible nodal connections. During impact, energy is absorbed through dual-density foam and macro-cavities, while modules move independently to reduce rotational forces transmitted to the head. 

No. OBLIK is engineered to reduce overall helmet weight while improving impact management by placing material only where it is structurally necessary. 

OBLIK improves ventilation through continuous airflow channels, larger strategically placed true-vents, and reduced internal material blockage. 

OBLIK is a fully integrated impact-management system rather than a removable insert or slip layer similar to MIPS. 

We’re always excited to connect with passionate athletes and creators.
