Product description
LIEGI Photochromic Cycling Glasses
LIEGI is the new DEMON cycling glasses model designed for riders who want high performance, full protection, and superior comfort on every ride.
Created to support cyclists on the road, gravel, and MTB trails, it combines a next-generation mirrored photochromic lens with an ultralight frame, adjustable nose pad, and adjustable temples for an even more customizable and secure fit.
Ideal for road cycling, mountain biking, gravel riding, and cycling tours, LIEGI naturally adapts to changing light and weather conditions, delivering consistently clear vision and effective protection all year round.
Design and functionality
LIEGI was created to offer the perfect balance of style, technology, and functionality.
Its wraparound structure effectively protects the eyes from wind, dust, insects, and debris, while the modern, dynamic design gives the glasses a sporty yet refined look.
The mirrored DCHROM® photochromic lens automatically adjusts its tint according to ambient light: it becomes lighter when brightness decreases and darkens quickly under intense sunlight, always ensuring the right visual comfort.
This feature makes LIEGI especially versatile for rides that start early in the morning, continue in full daylight, or end at sunset, without the need to change lenses.
Superior comfort and customized adjustment
One of LIEGI’s key 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 solution that further improves stability, support, and comfort.
The result is a pair of glasses that stays firmly in place even on the most technical or uneven sections, reducing unwanted movement and providing a constant feeling of security while riding.
Its unisex fit, suitable for both men and women, makes it an extremely versatile choice for every type of cyclist.
Perfect for every discipline
Road bike
On the road, LIEGI offers aerodynamic protection and constant visual comfort.
The wide lens helps shield the eyes from air, dust, and insects, while the photochromic technology effectively handles the continuous changes in brightness typical of paved routes.
Mountain Bike
For MTB use, LIEGI provides effective protection from branches, mud, stones, dust, and debris.
The lightweight yet durable frame, combined with the adjustable fit, ensures stability even on rougher trails and more demanding descents.
Gravel and cycling tours
For those who love adventure and long distances, LIEGI is a reliable ally.
Its great versatility makes it ideal for tackling mixed terrain, sudden weather changes, and long days in the saddle with maximum comfort.
Mirrored DCHROM® photochromic lens
DCHROM® lenses represent an advanced technical solution for outdoor sports.
Thanks to photochromic technology, the lens reacts to UV rays by gradually changing its tint according to the intensity of the light.
LIEGI’s lens covers category 1–3, making it suitable both in low-light conditions and in bright sunshine. This allows for extremely wide usability, from cloudy days to the brightest summer rides.
In addition, UV400 protection ensures maximum shielding against UV-A and UV-B rays, helping protect the eyes during every sporting activity.
