An aerodynamic road and gravel helmet that puts advanced protection right where you need it. The Lazer Sphere KinetiCore pairs a slim, fast profile with integrated rotational impact technology and premium ventilation — delivering speed, security and all-day comfort for road riders and gravel adventurers alike.

Highlights

• KinetiCore rotational protection: Controlled Crumple Zones built into the EPS foam manage both direct and rotational impact forces without the need for an external liner or separate MIPS layer — trusted protection in a clean, low-bulk design.
• Aerodynamic profile: Closed-off, streamlined shape reduces drag so you can push harder on road and fast gravel segments.
• 16 vents with internal air channelling: A large front vent and floating front headband maximise airflow through the helmet to keep you cool on long rides.
• Advanced TurnSys fit system: A single rear dial delivers precise, stable adjustment on the move — dial in your fit without breaking rhythm.
• Integrated eyewear docking: Stow your sunglasses securely on the helmet when not in use, so they stay put on descents and in tunnels.
• Universal LED light compatibility: Built-in Direct Mount at the rear accepts the Lazer Universal LED accessory (sold separately) to boost your visibility.
• Polygiene Biostatic padding: Antibacterial, recycled straps and treated padding resist odour-causing bacteria, keeping the helmet fresh ride after ride.

KinetiCore technology

KinetiCore is Lazer's built-in rotational impact protection system. Rather than adding an external liner or separate slip-plane layer, Lazer engineers Controlled Crumple Zones directly into the EPS foam structure. On impact, these zones strategically crumple and redirect energy away from the head, managing both direct and rotational forces. The result is a lighter, cleaner helmet with no extra bulk and no compromise on safety.
