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! ;)

realy good product
Best Product In 1499
Davesh (India) Used for 2 week or less
Best product for the new ones
But the problem is not molded
And packing is not proper
Light Weight And Solves the purpose
Gaurav (India)
A really nice purchase. Looks sporty and solves the purpose. Has a tightening mechanism inside with an adjuster knob so fits the head perfectly.
Light weight and no problem wearing for long rides.
What could have been better? A little more of the air-vents but still its doable.
Worth The Money
SACHIN (India) Used for 3 to 8 weeks
