XC Race Photochromatic - Black

Entirely designed and developed, from the initial sketches to the final mock-up, in France at the B'Twin Village (Lille). These XC SUNGLASSES are the fruit of the work of an expert team of passionate cross-country mountain bikers.

The Rockrider team designed and tested these XC RACE SUNGLASSES with their user testers and our technical partner, Milton Ramos. All in a variety of conditions to offer high-end sunglasses for cross country riding.

Photochromatic lenses automatically adjust to light intensity.
The lens changes tint in about 30 seconds (45 seconds to clear).
The brightness feeling varies little, even if the outside brightness changes.
For example, when cycling, the change in tint is hardly noticeable.
The tint adjusts gradually so that the eye can adapt.
A cold temperature will activate (shade) the lens more rapidly.

Full coverage frame to protect from cuts in the event of a fall.
Frame material: polyamide.
Nose pads material: impact resistant polycarbonate.
Arms material: polyamide + rubber.
Arm tip material: polyamide + rubber.
Sizing: suitable for narrow/medium/large faces.

Category 1 to 3 photochromatic lenses: filters 15% to 55% of light at 23°C.

In cold weather (under 10C°) the variation in the tint is greatly diminished.

Full UV protection filter

We've treated the transparent glass on the XC Race - Red and XC Race - White glasses with a new treatment that limits steam.

Unlike current coatings, this technology is permanent.

The coating absorbs condensation like a sponge so that your vision remains clear during cross-country rides.

In certain very demanding conditions, fog may appear on the lenses for a short period of time.

To effectively clean the treated lenses, rinse them under water with or without liquid soap and gently rub with your fingers. To wipe them, simply dab them with a soft (glass cleaning) cloth without rubbing.

Allow to air dry, then wipe gently with a soft, dry (glass cleaning) cloth to remove any remaining marks.
