We recommend replacing your helmet in 2 cases: 1/ After a fall In the event of a fall, the material of your helmet can deteriorate or even break. Sometimes, you won't even notice. That is why we recommend replacing it if you have the slightest doubt. 2/ After 5 years of use The foam of your helmet degrades over time. It can deteriorate due to impact, where it is stored, the climate, and its use. We recommend replacing your helmet at least every 5 years
Follow these 2 quick steps to adjust your helmet in 5 minutes: 1/ Clip the 2 straps with the buckle: check that you can still slide 2 fingers between the strap and your chin. 2/ Finally, adjust the tightness around your head. The helmet should be in contact with your head, without tipping forward, backward, or sideways, even when you're moving.
This helmet is not adapted to attach a headlamp or other lighting source. Do you want to film your rides with a mountable camera? For your safety, we recommend attaching your sports camera directly onto the handlebars or on your torso with a suitable harness.
