We recommend replacing your helmet in 2 cases:1/ After a fall:In the event of a fall, your helmet's material 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 deteriorates. It can deteriorate due to impact, where it is stored, the climate, and its use. We therefore recommend replacing your helmet at least every 5 years.

3 quick steps for adjusting your helmet in 2 minutes:1/ If needed, pull your ponytail through the back of the helmet (lower the dial's rim).2/ Adjust and clip the buckles on the 2 straps: check that you can still slide 2 fingers between the strap and your chin.3/ Adjust the tightness around your head using the rear dial.The helmet should be in contact with your head, without tipping forward, backward, or sideways, even when you're moving.

This Rockrider ST 500 mountain bike helmet has a detachable visor.Unclip and reclip it whenever you want using the connector on each side.However, we recommend keeping it on your helmet during your mountain bike rides. It protects you from branches, sun, and spray.Remember to wear glasses for additional eye protection from vegetation when tearing down singletracks and from any dust you kick up.

The helmet can seem restrictive at first. The Rockrider team is unanimous: for mountain biking, helmets have an important role to play.Moreover, we all wear a helmet. For us, helmets are essential. Don't forget to wear one! ;)

Right from the start, we designed this helmet to work with long hair.It's never easy to fit your helmet over your ponytail when getting ready for a mountain bike ride.But you no longer need to stuff your hair inside your helmet. Just pull down the tongue: it's quick and easy. You can then use the dial to adjust the helmet to your size!
