Product description

Designed for XC (cross country), both competitive and recreational, but always seeking greater performance.

Hit the mountain bike trails with confidence. You'll love this lightweight MTB XC helmet for its ventilated design on the climb. Protects against rotational impacts thanks to MIPS Technology.

Description

Designed for XC (cross country), both competitive and recreational, but always seeking greater performance.

Features

13 vents. Chinstrap fastening: buckle Occipital adjustment: 3D dial Comfort foam: removable and washable (available from after-sales) Visor: Inmold polycarbonate MIPS protection (Multi-Directional Impact Protection System), reduces rotational forces during oblique impacts, offering superior impact protection.

VENTILATION

This XC helmet was designed with 13 strategically-placed openings for maximum ventilation, particularly on climbs at lower speeds. In mountain biking, the head position is often higher than on a road bike, so we've optimised the openings so that they are particularly effective in this position.

How do you choose your mountain bike helmet size?

To find out your helmet size, just measure your head size (from the forehead to the top of the neck). This mountain bike helmet is available in three sizes: S: 52 - 55 cm M : 55 - 59 cm L: 59 - 62 cm

Weight

S: 290 g M: 320g L: 350g

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 deteriorate 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 deteriorate due to impact, where it is stored, the climate, and its use. We recommend replacing your helmet at least every 5 years

How do you adjust the 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/ 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.

COMBINING SPORT & 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! ;)
