The Lazer Cage KinetiCore is a lightweight full face mountain bike helmet built for enduro and downhill riders who demand real protection without the weight penalty. Featuring Lazer's integrated KinetiCore rotational impact protection — the world's first fully integrated rotational impact system — and a 5-star Virginia Tech safety rating, the Cage KC raises the bar for gravity riding head protection.

Highlights

• KinetiCore rotational impact protection: Controlled crumple zones are built directly into the EPS liner, managing both direct and rotational forces without the need for a separate MIPS liner — keeping weight low and protection high.
• 5-star Virginia Tech rating: The Cage KinetiCore is the first full face helmet to earn a 5-star rating from Virginia Tech's independent helmet testing programme — the gold standard in impact protection assessment.
• Breakaway visor: The visor is engineered to detach cleanly on impact, reducing the rotational forces transmitted to the neck and reducing injury risk in crashes.
• Fidlock magnetic buckle: One-handed, glove-friendly magnetic closure makes buckling fast and secure before every run.
• Neck brace compatible: Designed from the ground up to work with all major neck brace systems — no adapters needed.
• 20 ventilation channels: Strategically routed air channels keep airflow moving through the helmet on climbs and trails alike.
• Fiberglass shell with carbon reinforcements: The lightweight shell construction combines fiberglass and carbon fibre for strength where it counts without excess weight.
• Secure goggle grip: Built-in goggle retention keeps your eyewear in place through rough terrain.

KinetiCore Technology

Rather than adding a separate rotational liner, Lazer's KinetiCore system integrates controlled crumple zones directly into the EPS foam. Strategically placed variable-density foam blocks — inspired by automotive crumple zone engineering — compress and redirect energy during both direct and angled impacts. The polycarbonate shell connects to the EPS liner at cylindrical contact points, allowing controlled movement between the layers when it matters most. The result is a lighter, cleaner, and measurably safer helmet with no add-on liner to degrade or replace.

Construction & Fit

The Cage KinetiCore features an in-mould fiberglass and carbon fibre chin bar construction. The interior uses interchangeable cheek and brow padding for a personalised fit. The size L fits head circumferences of 58–60 cm. Chin strap closure is handled by the Fidlock magnetic buckle system for fast, secure glove-friendly operation.
