TECHNICAL INFORMATIONS

How do you choose your mountain bike helmet size?

To find your helmet size, simply measure the circumference of your head (around the forehead). The ST 500 MTB helmet comes in two sizes:
M: 55 - 59 cm
L: 59-62 cm

Weight and dimensions

Size M weight: 325 g
Size L: 380 g

Dimensions
Length: 30 cm
Width: 21 cm Height: 15.5 cm

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 deteriorates. It can deteriorate due to impact, the place it’s stored, the climate, and its use. We therefore recommend replacing your helmet at least every five years.

How do I adjust my helmet?

Three easy steps for adjusting your helmet in 2 minutes:

1. If necessary, pull your ponytail through the back of the helmet (lower the dial's rim).

2. Clip the straps together with the buckle and adjust: make sure you can slide two fingers between the strap and your chin.

3. Adjust the tightness around your head using the rear dial.

The helmet should be in contact with your head, without tipping forward, backward, or sideways, even when you're moving.

How to attach/remove the visor

The ST 500 Rockrider mountain bike helmet has a detachable visor.

Unclip and reclip it whenever you want using the connectors on each side.
However, we recommend keeping it on your helmet during your mountain bike rides. It protects you from branches, sun, and splashes.

Remember to wear glasses for additional eye protection from vegetation and any dust you kick up when tearing down singletracks.

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!

A helmet for long hair

Right from the start, we designed this helmet to handle long hair.
Fitting your helmet over your ponytail is never easy when getting ready for a mountain bike ride.

Gone are the days of stuffing your hair inside your helmet. Just pull down the tongue: it's quick and easy. You can then use the dial to adjust the helmet to fit you!
