ALBA OPTICS DELTA BLUE GLOSSY VZUM™ F-LENS CLASSIC

One pair of glasses. Every ride.

Australian cyclists rarely ride in one lighting condition.

A typical ride might begin before sunrise, move through shaded roads and tree cover, climb into bright sunshine, then finish beneath a completely different sky. The ALBA OPTICS DELTA with VZUM™ F-LENS Classic was developed precisely for these conditions.

Handmade in Italy, the DELTA combines ALBA OPTICS' unmistakable heritage-inspired design with modern photochromic lens technology that continuously adapts as the environment changes around you.

The VZUM™ F-LENS Classic automatically adjusts between Category 1 and Category 3 protection depending on UV exposure. Rather than forcing riders to choose between a bright-light lens or a low-light lens, the lens continuously responds throughout the ride to maintain clear vision and balanced contrast.

For Australian riding conditions this means greater versatility across:

• dawn bunch rides

• winter training sessions

• shaded gravel roads

• bright coastal routes

• changing mountain weather

• long endurance rides

The lens has been developed to preserve natural colour perception while reducing eye fatigue. Road surfaces, potholes, gravel texture, painted lines and changing terrain remain easier to interpret as lighting conditions evolve.

At just 26 grams, the DELTA is remarkably light and comfortable for all-day riding. The frame is constructed from premium TR90, a lightweight and highly durable material chosen for its flexibility, resilience and long-term comfort.

Integrated lens ventilation helps minimise fogging during hard efforts, cool starts and rapidly changing temperatures. The interchangeable lens platform also allows future lens upgrades while preserving the distinctive DELTA silhouette that has become one of the most recognisable designs in modern cycling.

At Chainsmith, we particularly recommend the VZUM™ F-LENS Classic for Australian riders seeking one eyewear solution that can comfortably handle everything from dark winter mornings to bright summer afternoons.

One lens.

One ride.
