You can adjust the size of your Neuronic LIGHT using the dial at the back of the helmet. Simply twist the dial—similar to a bike helmet adjuster—to tighten or loosen the fit until it feels secure and comfortable.
For additional comfort and customization, the foam pads at the front and back of the helmet are removable. You can:
- Swap them with the smaller pads included in your accessories bag, or
- Remove them entirely if you need more space
This allows you to fine-tune the fit for different head sizes and preferences.
