TECHNICAL INFORMATION
HOW DO YOU CHOOSE YOUR MOUNTAIN BIKE HELMET SIZE?

To find out your helmet size, just measure your head size (from the forehead to the top of the neck). This mountain bike helmet is available in two sizes:
M: 53 - 59 cm
L: 59 - 61 cm

WHEN SHOULD I REPLACE MY HELMET?

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

HOW DO I ADJUST MY HELMET?

3 quick steps to follow 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/ Adjust the straps so that they form a "Y" on each side of your ears. Just below the ear.

3/ 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.

HOW DO I ATTACH/REMOVE THE VISOR?

The Rockrider 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.

COMPATIBLE ACCESSORIES

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 sport camera directly onto the handlebars or on your torso with a suitable harness.

M: 286 g
L: 320 g

COMBINING SPORT & SAFETY

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! ;)
