Leatt MTB Gravity 4.0 V23 Bicycle Helmets

The Gravity 4.0 helmet delivers downhill-certified protection in a breathable, lightweight package. Ideal for enduro racers, park laps, and e-MTB missions, this helmet provides level protection and speed when the trail gets technical.

Executive Protection and $360^\circ$ Turbine Technology ✅

Engineered for protection against rotational and linear forces:

Shell: Features a DH certified lightweight Polymer shell.
Impact Foam: Uses Dual density, in-molded EPS + EPO impact foam for superior energy absorption.
$3$ -in- $1$ Safety System: The foam combines with $360^\circ$ Turbine Technology to offer a unique safety system protecting against:
- Low-speed impacts (energy absorbing material in turbines absorbs energy associated with concussion).
- High-speed impacts.
- Rotational forces (turbines enable the helmet to move slightly, reducing peak acceleration to the head & brain). ✅

Ventilation, Comfort, and Features ✅

Ventilation: Maximized with $22 \text{ vents}$ to keep air moving even at lower speeds.

Important Sizing Guide:

To find your size, measure the circumference of your head just above the eyebrows (in cm).
The cheek pad size refers to the thickness of the pads supplied with the helmet, which affects the snugness around the cheeks.
A well-fitting helmet should feel snug but not painfully tight.
