TECHNICAL INFORMATIONS

HOW DO YOU CHOOSE YOUR MOUNTAIN BIKE HELMET SIZE?

To figure out your helmet size, you need to measure your head.
1/ Get a tape measure
2/ Place it around your head, about 1 cm above your eyebrows and ears. Do not pull too tight. You will be able to tighten your helmet.
3/ If you are between sizes, choose 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 become damaged 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 become damaged due to impacts, 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/ Lastly, 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 is not suitable for attaching a headlamp or other lighting source. Do you want to film your rides with a mountable camera? For your safety, we recommend attaching your sports camera directly onto the handlebars or on your torso with a suitable harness.

COMBINING SPORTS & 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! ;)

Response of the brand

Hi Yong Choo


Thank you for your support and kind review.


Do note that any helmet, should it encounter any impact from any accidents, should be replaced immediately. It is also recommended that a helmet should be replaced with a new set after 3 - 4 years of usage from wear and tear.

Size Problem
Mayank (India) Used for
The size mentioned on the size guide and when one actually buys is whole lot different. Do not go by the size and measure your head with a measurement tape. Useless buying on a website. I will prefer going to store and buy the helmet. Wasted my money.
