LIEGI Cycling Glasses with DCHROM® Photochromic Lens

LIEGI is the new cycling eyewear by DEMON, designed to support you on every ride with maximum versatility, comfort, and protection. Ideal for road cycling, mountain biking, gravel riding, and cycle touring, it is made for cyclists who want consistently sharp vision, a customizable fit, and reliable performance in all light and weather conditions.

Designed for advanced sports use, LIEGI combines a lightweight yet durable frame with a next-generation photochromic lens, offering the perfect balance of functionality, protection, and style. Its unisex fit makes it suitable for both men and women, with a stable and comfortable fit even during longer and more demanding rides.

Dynamic vision in every lighting condition

At the core of LIEGI is the DCHROM® photochromic lens, category 0–3, engineered to adapt quickly to changes in ambient brightness. The lens starts in an almost transparent state and gradually darkens up to category 3, always ensuring the best possible visibility while riding.

This makes the glasses suitable for an extremely wide range of situations: from the early morning hours to the brightest days, from wooded trails to fully sun-exposed sections, all the way to evening rides or cloudy skies. The transition is smooth and natural, helping reduce eye strain and maintain a clear, relaxed view of the route.

Completing the lens performance is UV400 protection, which ensures maximum shielding from UVA and UVB rays, effectively protecting the eyes during every outdoor activity.

Custom comfort: adjustable nose pad and temples

One of LIEGI’s strengths is its ability to adapt precisely to the rider’s face. In addition to the adjustable nose pad, this model also features adjustable temples, a detail that further enhances fit customization.

The result is stable, secure, and comfortable eyewear that stays firmly in place even during the most intense phases of sporting activity, on rough terrain, or during long endurance rides. Adjusting the nose pad and temples allows you to optimize support, stability, and comfort, improving the fit under a helmet and reducing pressure points.

Lightweight strength with a TR90 Ultralight frame

LIEGI’s frame is made of TR90 Ultralight, a technical material appreciated for its combination of lightness, flexibility, and durability. This allows the glasses to provide a solid and reliable structure without feeling heavy on the face.

Weighing only 28 grams, LIEGI ensures lasting comfort even after many hours of use. The lightweight frame makes the riding experience feel more natural, while its flexibility allows it to adapt better to different face shapes.

High performance in every cycling discipline

Mountain Bike

LIEGI is the ideal choice for Mountain Bike riders, from enthusiasts to the most demanding cyclists. The wide lens and protective design help shield the eyes from branches, leaves, dust, insects, mud, and debris typically found on off-road trails.

The DCHROM® photochromic lens is particularly effective on trails with frequent light changes, such as wooded sections or transitions between shaded areas and fully open terrain. The adjustable fit, combined with the lightweight frame, guarantees stability even on the most technical terrain.

Road Cycling

On the road, LIEGI provides excellent protection from wind, dust, and insects, improving visual comfort even at high speeds. The lens quickly adapts to changing light conditions, making it perfect for both very bright days and long rides with variable conditions.

The lightweight structure and the ability to adjust both the nose pad and temples ensure a precise, stable, and comfortable fit, ideal for tackling climbs, descents, and long distances without distractions.

Gravel and Cycle Touring

Versatile by nature, LIEGI is also perfectly suited to gravel riding and cycle touring, disciplines where comfort, protection, and adaptability make all the difference. It is the right eyewear for those looking for a single model to use all year round, on mixed routes and in changing weather conditions.

The photochromic lens allows you to tackle dirt roads, white roads, asphalt, and long touring routes with the same effectiveness, always maintaining balanced vision and constant protection.

Technology and materials

DCHROM® photochromic lenses activate when exposed to UV rays, triggering a reaction that causes them to gradually darken according to light intensity. When brightness decreases, the lens gradually returns to a lighter state, ensuring continuous and automatic adaptation.

Designed to deliver high performance in sports use, they ensure:

• automatic adaptation to light
• total UV protection
• prolonged visual comfort
• excellent versatility in all weather conditions

The TR90 Ultralight frame completes the design with a perfect mix of lightness, flexibility, and durability, created to withstand intense use while always ensuring a comfortable fit.
