HOW DO YOU CHOOSE YOUR MOUNTAIN BIKE HELMET SIZE?
To find your helmet size, just measure your head's circumference. 1/ Get a tape measure 2/ Place it around your head, about 1 cm above your eyebrows and ears. Don't squeeze too tight. The helmet will be just as tight. 3/ If the measurement falls between two sizes, opt for the larger size. This mountain bike helmet is available in two sizes: M: 53 - 57 cm L: 57 - 62 cm Please note: for safety reasons, helmets cannot be returned.
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?
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 sport camera directly onto the handlebars or on your torso with a suitable harness.
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! ;)
Store the helmet in a dry place away from direct sunlight, and avoid high temperatures (> 60°C). Clean the outside with a simple soft sponge and neutral soap.
