Photochromic Cycling Glasses for BDC and MTB: ROUBAIX
ROUBAIX is the latest model of cycling glasses from DEMON, designed specifically for fans of gravel and mountain biking. Equipped with a mirrored photochromic lens, it represents a significant advancement in the world of sports eyewear.
These glasses are tailored for cyclists seeking a photochromic lens that combines an attractive design with reliable performance. Suitable for mountain biking, road cycling, and gravel riding, they can be worn in various lighting and atmospheric conditions throughout the year. The latest-generation photochromic lenses adapt to light variations, darkening when necessary.
What makes this unique lens special is its subtly veiled base color, allowing athletes to use ROUBAIX glasses even in low-light situations, such as at sunset or during evening rides, while providing essential protection from atmospheric elements.

As shown in the photo, the lens is suitable for any lighting conditions, making it particularly useful in low-light situations, such as very cloudy or rainy weather, as well as when returning home after sunset. However, it also delivers excellent performance in bright conditions.
Sports Types:
Mountain Bike: ROUBAIX is the ideal choice for mountain biking enthusiasts, whether they are amateurs or professionals. The wide frame provides maximum protection in wooded environments, shielding the eyes from leaves, branches, dirt, and insects. Despite its size, the glasses weigh only 25 grams. The special DCHROM® latest-generation mirrored lens features a slightly sheer base color, reaching category 3 in maximum sunlight and effectively reflecting light. It dynamically adapts to variations in light along the path, lightening and darkening as needed. Additionally, the lens is shatterproof, ensuring resistance to intense impacts and guaranteeing maximum safety.
Racing Bike: ROUBAIX is also an excellent companion for road cycling enthusiasts. Its wide shape offers complete protection from air, dust, insects, and other potential hazards. The lens adapts dynamically to changes in light, darkening or lightening as required. This feature makes it ideal for intense lighting conditions, common during summer, and for prolonged use. The glasses provide optimal comfort, thanks to their ultra-light and elastic frame and hypoallergenic rubberized components. Once you experience their performance, you won’t want to be without them.
Gravel, Cyclocross, Cycle Tourism, and Other Disciplines: ROUBAIX is recommended for every cycling discipline. It offers complete protection from external elements, intense light, and accidental impacts. Stability, comfort, and lightness are fundamental characteristics of these cycling glasses, making them ideal for those seeking optimal eye protection with an aggressive design.
Regardless of the discipline, ROUBAIX combines the versatility of the photochromic lens with the aesthetics of the mirrored lens, allowing athletes to enjoy glasses with a strong visual impact while benefiting from advanced photochromic technology.

IMPORTANT NOTE: THE MIRRORED COLOR DOES NOT AFFECT YOUR EXTERNAL VISION, AS THE LENS IS INTERNALLY SMOKE-COLORED.
Technical Characteristics and Materials:
The new DCHROM® Photochromic lenses represent advanced technology that activates a reversible chemical reaction when exposed to UV radiation or sunlight, causing them to darken. Once the light exposure stops, the lenses gradually return to their original transparency. Made from high-quality polycarbonate, these lenses offer two significant advantages: they substantially reduce weight compared to conventional materials and ensure safety in the event of an impact, as they do not shatter into fragments that could harm the eyes. These high-tech filters also provide protection against UV rays, ensuring both safety and comfort.
The DCHROM® lenses evolve from a lightly veiled color to reach category 3 in maximum sunlight conditions. In addition to their rapid transition from light to dark, these lenses offer remarkable comfort for the eyes, even on days with strong sunlight and during prolonged use.
The ROUBAIX cyclist's frame is made with ultra-light TR90 material, combining carbon fiber and nylon. Despite the frame's apparent size, the glasses weigh only 25 grams in total. This design is crafted for athletes who value products made from technical materials that ensure maximum protection and safety.
The frame is elastic and adapts to the shape of the head, guaranteeing optimal comfort without constriction and ensuring maximum stability during sporting activities.
ROUBAIX is essential for those seeking ultra-light mirrored photochromic cycling glasses, ideal for gravel and mountain biking in every cycling discipline.
Made from innovative materials, these cycling glasses with DCHROM® mirrored photochromic lenses are 20% lighter than conventional options and more resistant to impacts and stress. Thanks to these characteristics, their durability over time is enhanced, ensuring optimal performance even in the most demanding conditions.
