helmet. Please note that on some helmets, the color of the EVA comfort foams (those in contact with the top of the head) may vary.
WHEN SHOULD YOU CHANGE YOUR HELMET?
We recommend changing your helmet in 2 cases:
1/ After a fall:
In the event of a fall, the material of your helmet may deteriorate or even break. Sometimes, you may not even notice it. That's why we advise you to replace it if you have any doubts.
2/ After 5 years of use:
Foam deteriorates. It can be damaged by impact, storage, climate and use. We therefore advise you to change your helmet at least every 5 years.
HOW TO ADJUST YOUR HEADSET
3 quick steps to adjust your helmet in 2
minutes:
1/ If necessary, slip your ponytail over the back of the helmet (pull down the knob).
2/ Adjust and clip the buckle on the 2 straps: check that you can still slip 2 fingers between the strap and your chin.
3/ Adjust the headband with the rear knob.
The helmet must be in contact with your head, without tilting forwards, backwards or sideways, even when you're moving.
