Product description
FIANDRE Photochromic Cycling Sunglasses for Road Cycling & MTB
FIANDRE is the new cycling eyewear model by DEMON, developed for riders seeking high performance combined with a more fluid and elegant design.
Compared to the ROUBAIX model, FIANDRE stands out for its less angular and more streamlined lens shape, designed to deliver a more harmonious look without sacrificing the protection and coverage typical of shield-style sunglasses.
Equipped with a mirrored photochromic lens, FIANDRE is an advanced technical solution for Mountain Bike, Road Cycling, and Gravel enthusiasts, ideal for tackling any light and weather condition throughout the year.
Design and Functionality
FIANDRE is designed for cyclists who want a high-performance photochromic lens paired with a modern, less aggressive design compared to ROUBAIX.
The latest-generation photochromic lens automatically adapts to changes in light, darkening in strong sunlight and quickly lightening in low-light conditions.
The slightly tinted base color allows the sunglasses to be used even at dusk, under overcast skies, or during evening rides, offering protection from wind and weather without compromising visibility.
Shield-Style Cycling Sunglasses for MTB & Road Cycling
Blue Mirrored Photochromic Lens – FIANDRE Model
As shown in the images, FIANDRE’s lens delivers excellent performance in all lighting conditions, proving especially effective in critical situations such as rain, heavy cloud cover, or rides after sunset, while still providing optimal protection in bright sunlight.
Sports Applications
Mountain Bike
FIANDRE is the ideal eyewear for MTB riders, from amateurs to professionals.
The wide frame effectively protects the eyes from branches, leaves, dirt, insects, and debris typical of off-road trails. Despite the generous coverage, the sunglasses weigh only 25 grams, making them extremely lightweight and comfortable.
The latest-generation mirrored DCHROM® lens features a slightly tinted base color and reaches Category 3 in conditions of maximum sun exposure, reflecting light and dynamically adapting to changing trail conditions.
The lens is also shatterproof, ensuring maximum safety even in the event of strong impacts.
Road Cycling
FIANDRE also proves to be a reliable companion on the road.
The streamlined lens shape offers complete protection from wind, dust, and insects, enhancing visual comfort during long rides. The photochromic lens reacts quickly to the light changes typical of road routes, making FIANDRE ideal for summer use and prolonged training sessions.
The ultra-lightweight and flexible frame, combined with hypoallergenic rubber inserts, ensures stability and comfort even at high speeds.
Gravel, Cyclocross, Cycle Touring & Other Disciplines
FIANDRE is recommended for all two-wheel disciplines.
Its versatility, lightness, and stability make it a complete pair of sunglasses, capable of protecting effectively from both intense light and accidental impacts, with a cleaner and less aggressive design than ROUBAIX.
It is important to note that the mirrored coating color does not affect vision: internally, the lens remains smoke-colored.
Technical Features & Materials
DCHROM® photochromic lenses represent advanced technology: they react to UV rays by activating a reversible chemical process that allows the lens to darken and gradually return to a lighter state as UV exposure decreases.
Made from high-quality polycarbonate, they offer:
- Low weight
- Maximum safety in case of impact (no fragments)
- Total UV protection
DCHROM® lenses start from a slightly tinted base color and reach Category 3, ensuring excellent visual comfort even on very sunny days.
Frame
The FIANDRE frame is made from TR90, a special blend of carbon fiber and nylon that is:
- Ultra-lightweight (only 25 g)
- Flexible and durable
- Stable even on rough terrain
It adapts perfectly to the shape of the face without tightening, ensuring optimal comfort and secure fit during sports activity.
FIANDRE is the ideal choice for cyclists looking for ultra-lightweight mirrored photochromic cycling sunglasses, featuring a more streamlined and less angular design than ROUBAIX, without compromising on protection, technology, or performance.
