TECHNICAL INFORMATIONS

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. Or 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 these two 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’s why we recommend replacing it if you have the slightest doubt.

2. After five years of use
The foam of your helmet degrades over time. It can deteriorate due to impact, the place it’s stored, the climate, and its use. We recommend replacing your helmet at least every five years

How do I adjust my helmet?

Two easy steps to adjust your helmet in 5 minutes:

1. Clip the straps together with the buckle: make sure you can slide two 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.

Compatible accessories

This helmet isn’t designed to be fitted with a headlamp or other light sources. Do you want to record your rides with a mounted camera? For your safety, we recommend attaching your sports camera directly on the handlebars or on your torso with a suitable harness.

Combining sports and safety

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

Tight
Song (Canada) Used for 3 to 8 weeks
It’s tight and small than I think
Ok quality
Sidharth (India) Used for 3 to 8 weeks
The build looks cheap and flimsy. However,it fits good and is light weight.I would have loved to see better quality build. The pasting on places also looks uneven and cheap.
