Laurent Fignon, The Professor, wins the Giro d’Italia in 1989 only a few months before the fall of the Berlin Wall. Computers make their way into homes and offices. Gianni Bugno makes people dream. Miguel Indurain becomes the last of the biggest champions. It is the beginning for a Russian, Berzin, and the only time for the pirate, Pantani, who is responsible for a rebirth in the passion for Italian cycling.

The material of the frames is Tr90, made from nylon and carbon fiber, organically compatible and safe to the skin, even after a prolonged use. It is 20% lighter that other conventional materials and it offers more protection against crashes and tractions. It provides a high resilience without deformation when exposed to high temperatures, after being bent, it reverts to its original shape.

The glasses wearability allows a perfect vision when shifting your eyes from the pedals to the road. This particular aspect enables the athlete to stay focused on his performance without interferences.  The temples are strong and guarantee to stay put even in case of shocks or sudden head movements.

Features

• Ventilated VZUM™ lens to help prevent fog - The horizontal slots in the lens allows optimal ventilation of the upper internal space, helping to eliminate condensation and fogging.
• Interchangeable VZUM™ lens - The interchangeable lens fits perfectly to the flexible frame while maintaining aesthetic detail. You can create hundreds of combos.
  
• Compatible with the Optical Clip
• Ergonomic temple tips - The end of the temple arms are tapered and flexible. Thanks to their arched shape they ensure a perfect fit and won’t move out of place.
• Lighter Tr90 frame
• Frame weight: 10 gr

ALBA OPTICS DELTA BLU GLS VZUM™ F-LENS BEETLE

The ALBA OPTICS DELTA is one of the defining silhouettes of modern cycling eyewear — combining the style and spirit of cycling's golden era with contemporary Italian optical technology.

Handmade in Italy, the DELTA was developed for riders who spend long hours on the road and experience constantly changing light conditions throughout a ride. For Australian cyclists, this often means rolling out before sunrise, riding through shifting dawn light, climbing into bright sunshine and returning home beneath a completely different sky.

This version pairs the striking Blue Glossy frame with the VZUM™ F-LENS BEETLE photochromic lens, specifically developed to automatically adapt to changing light conditions throughout the day.

Unlike fixed-category lenses, the F-LENS BEETLE transitions between Category 1 and Category 3 protection depending on UV exposure. This allows riders to maintain excellent visibility during:

• early morning bunch rides

• shaded forest roads

• cloudy winter conditions

• bright coastal roads

• intense Australian summer sunshine

• late afternoon training rides

For Australian cyclists, this versatility is one of the greatest advantages of photochromic technology. Rather than choosing between a low-light lens and a bright-sun lens, the F-LENS BEETLE continuously adjusts as conditions evolve, helping maintain visual clarity throughout the ride.

The lens is designed to enhance contrast while preserving natural colour perception, allowing riders to better identify road surfaces, gravel texture, potholes, painted road markings and changing terrain. This becomes particularly valuable when moving rapidly between shade and sunlight, a common occurrence on many Australian roads.

The DELTA frame itself is constructed from lightweight TR90, a nylon and carbon-fibre composite material chosen for its flexibility, durability and long-term comfort. At just 26 grams, the DELTA remains exceptionally comfortable during long endurance rides, fast bunch rides and gravel adventures.

Integrated ventilation slots within the lens help reduce fogging and condensation during cool starts, hard efforts and rapidly changing temperatures. The interchangeable lens system also allows future lens changes while preserving the iconic DELTA aesthetic.

At Chainsmith, we deliberately select photochromic lenses because Australian riding conditions are rarely consistent. One ride can begin in darkness, move through fog, sunshine, shade and glare before finishing under completely different conditions.

The DELTA F-LENS BEETLE adapts with you.

One lens. One ride. Every condition.

A modern Italian classic built for Australian roads.

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.

One of the most versatile cycling eyewear systems available.

ALBA OPTICS DELTA BLUE GLOSSY VZUM™ F-LENS FIRE

Built for Australian light.

Australian cyclists often ride through the widest range of light conditions imaginable.

A ride may begin before sunrise, pass through shaded roads and tree cover, emerge into harsh summer glare, then finish beneath a completely different sky. The ALBA OPTICS DELTA with VZUM™ F-LENS FIRE was designed for exactly this reality.

Handmade in Italy, the DELTA combines one of modern cycling’s most iconic silhouettes with advanced photochromic lens technology that continuously adapts throughout the ride.

The VZUM™ F-LENS FIRE automatically transitions between Category 1 and Category 3 protection depending on UV exposure. Instead of forcing riders to choose between low-light visibility and bright-sun protection, the lens dynamically adjusts as conditions change, helping maintain clear vision from dawn bunch rides through to exposed midday roads.

For Australian road and gravel cyclists, this versatility becomes particularly valuable across:

• early morning training rides

• winter bunch rides

• changing mountain weather

• shaded forest roads

• bright coastal highways

• long endurance rides under strong Australian sun

The FIRE lens tint enhances contrast while maintaining a vibrant visual field, helping riders better distinguish road texture, gravel surfaces, potholes, painted road markings and changing terrain as light conditions evolve throughout the day. The photochromic technology continually adapts without requiring lens changes or carrying multiple pairs of glasses.

The DELTA frame is constructed from premium TR90, a nylon and carbon-fibre composite that is approximately 20% lighter than many conventional frame materials while offering exceptional resilience against impacts, deformation and prolonged exposure to heat. For Australian summers and long days in the sun, this stability becomes particularly important.

At just 26 grams, the DELTA remains remarkably comfortable during all-day rides. The frame shape provides a wide and natural field of vision while allowing riders to smoothly transition their focus between the road ahead, the wheel in front and their cycling computer without distraction.

Integrated ventilation ports within the VZUM™ lens help reduce condensation and fogging during cool starts, climbing efforts and rapidly changing temperatures. The interchangeable lens platform also allows future lens upgrades while preserving the unmistakable DELTA aesthetic.

At Chainsmith, we deliberately favour photochromic lens options because Australian riding conditions rarely remain constant. The F-LENS FIRE gives riders one of the most versatile eyewear solutions available for year-round road and gravel riding.

One lens.

From first light to full glare.

Exactly how Australian cyclists ride.
