TECHNICAL INFORMATIONS

How to choose your helmet size

To find your helmet size, simply measure the circumference of your head (around the forehead). The ST 500 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

Cushioning foam

A cushioning foam replacement kit is available for this helmet on our website.

Please note that on some helmets, the colour of the EVA cushioning foam (in contact with the top of the head) may vary.

When should I replace my helmet?

We recommend replacing your helmet in these two situations:

1. After a fall:
In the event of a fall, the material of your helmet can deteriorate or even break. Sometimes the damage isn’t visible. That’s why it should be replaced after a fall.

2. After five years of use:
The foam deteriorates. It can deteriorate because of an impact, where it’s stored, the climate, and use. We therefore recommend replacing your helmet at least every five years.

How do you adjust the helmet?

Three easy steps for adjusting your helmet in two 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 and remove the visor

The ST 500 mountain biking 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 in mountain biking.
We all wear helmets. For us, helmets are essential. Don’t forget to wear one!

A helmet for long hair

We designed this helmet for 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!

protective but fit isn’t super comfortable
CJ (Canada) Used for 4 to 6 months
Built to a price-point, this resembles all the generic helmets you find online from bit ecomm sites. It’s protective but the ratcheting mechanism used to tighten the suspension system tends to be very uncomfortable with some hot-spots at the rear, and the pawls inside the knob itself tends to wear out. Eventually, you won’t be able to tighten it as much as needed.
