What qualifies as “a vibe”? Pizza is the vibe. Cold beers with mates is the vibe. Mountain is the vibe. That song is the vibe. It’s a simple recipe, but whatever the vibe is should be so.

The limited edition VIBE Collection features a retro inspired tri-colour matte frame, available in our iconic models DELTA with VZUM™ lens PLASMA.

Light is a fundamental component that determines of all our choices. VZUM™ lenses have only one objective: to provide athletes with the maximum visual experience in all weather conditions and on all types of terrain. The range of colours carefully developed by ALBA Optics aims to enhance colour saturation and balance visual contrasts, thus increasing the perception of sharpness and details.

The material of which VZUM™ lenses are composed of is a durable ultra-light polycarbonate. This offers fundamental protection to avoid straining eyes and the lenses maintain these characteristics for the total cycle of use. Thanks to this versatility, VZUM™ lenses offer the best sports experience ever.

ALBA OPTICS JUMBO CHERRY GLOSSY VZUM™ F-LENS FIRE

Ride through every light condition Australia can throw at you.

The ALBA OPTICS JUMBO Cherry Glossy with VZUM™ F-LENS FIRE is built for riders who start early, finish late and refuse to let changing conditions dictate the ride.

For Australian cyclists, lighting conditions can change dramatically across a single ride. A dawn roll-out can quickly become blinding coastal glare. Mountain roads move between deep shade and harsh sunlight. Winter bunch rides begin in darkness before opening into bright blue skies.

The VZUM™ F-LENS FIRE was developed specifically to adapt to these shifts.

Using advanced photochromic technology, the lens automatically transitions between Category 1 and Category 3 protection depending on UV exposure. Instead of choosing between a low-light lens and a bright-sun lens, riders gain one adaptable solution capable of maintaining visual clarity from first light through to peak midday glare.

The FIRE lens enhances contrast while maintaining a vibrant visual field, helping riders better distinguish:

• road texture

• gravel surfaces

• potholes

• painted road markings

• changing terrain

• wheel movement during bunch riding

As conditions evolve, the lens continually adjusts while preserving natural colour perception and reducing visual fatigue. This becomes particularly valuable during long Australian endurance rides where the light rarely remains consistent for long.

The JUMBO platform itself delivers one of the largest fields of vision in the ALBA OPTICS range. The oversized VZUM™ J-LENS creates a calm and uninterrupted visual experience, allowing riders to smoothly transition focus between the road ahead, surrounding riders, the horizon and their cycling computer.

Constructed from lightweight TR90, the frame balances flexibility, durability and comfort across long rides. Despite its large lens profile, the JUMBO remains remarkably light, weighing approximately 26–27 grams depending on published model references.

Three integrated airflow ventilation ports help reduce condensation and fogging during:

• cold morning starts

• hard climbing efforts

• changing temperatures

• humid conditions

The adjustable temple tips allow riders to fine-tune fit and helmet compatibility while ensuring stability over rough roads and gravel sectors.

Finished in the stunning Cherry Glossy frame colour, the JUMBO blends contemporary performance with the unmistakable personality of modern Italian cycling culture.

At Chainsmith, we deliberately favour photochromic lenses because Australian riders rarely experience one lighting condition for an entire ride. The JUMBO F-LENS FIRE is one of the most adaptable eyewear systems available for riders who regularly train through dawn, glare, cloud cover and everything in between.

One pair of glasses.

One lens.

Every Australian road.

ALBA OPTICS JUMBO WHITE VZUM™ F-LENS FIRE

From first light to full glare.

Australian cyclists often ride through some of the most demanding light conditions in the world.

A ride may begin before sunrise, pass through shaded roads and tree cover, emerge into harsh coastal glare, then finish beneath bright summer sunlight. The ALBA OPTICS JUMBO with VZUM™ F-LENS FIRE was developed specifically for riders who need one lens capable of adapting across all of it.

Handmade in Italy, the JUMBO represents ALBA OPTICS’ most expansive and modern performance platform. Combining an oversized field of vision with lightweight construction and advanced photochromic technology, it is designed for riders who spend long hours on the bike and experience constantly changing conditions.

The VZUM™ F-LENS FIRE automatically transitions between Category 1 and Category 3 protection depending on UV exposure. Rather than forcing riders to swap lenses or compromise visibility, the lens continuously adapts as light conditions evolve throughout the ride.

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

• dawn bunch rides

• winter training sessions

• mountain descents

• shaded gravel sectors

• bright coastal roads

• long endurance rides under changing skies

The FIRE lens enhances contrast while maintaining a vibrant visual field, helping riders better identify road texture, gravel surfaces, potholes, painted road markings and subtle terrain changes. When moving rapidly between shade and bright sunlight, the lens adapts naturally while maintaining visual comfort and clarity.

One of the defining features of the JUMBO is its enormous field of vision. The oversized VZUM™ lens allows riders to smoothly transition focus between the road ahead, the wheel in front, the horizon and their cycling computer without interruption. During bunch riding, fast descents and endurance events, this creates a calmer and more confident visual experience.

The frame is constructed from premium TR90, a lightweight and highly durable material chosen for its flexibility, impact resistance and comfort during long rides. At just 26 grams, the JUMBO feels remarkably light despite its larger lens platform.

Three integrated ventilation ports within the lens help reduce condensation and fogging during cool starts, hard climbing efforts and rapidly changing temperatures. The interchangeable lens system also allows riders to adapt the eyewear for different seasons and conditions while preserving the distinctive JUMBO silhouette.

At Chainsmith, we deliberately select photochromic lens options because Australian riding conditions rarely remain consistent. One ride can contain darkness, fog, shade, sunshine and glare — sometimes all before breakfast.

The JUMBO F-LENS FIRE adapts through every phase of the ride.

One lens.

One pair of glasses.

Built for how Australians actually ride.

A cosmic view of the road ahead.

Photochromic Alba Optics JUMBO sunglasses designed for Australian road cycling conditions

The latest ALBA OPTICS JUMBO is one of the most distinctive eyewear releases to arrive at Chainsmith — combining bold Italian design, exceptional visibility and practical performance for Australian riding conditions.

Also available in Black

Handcrafted in Italy, the JUMBO was created for riders who demand more from their eyewear than simple sun protection. The oversized VZUM™ J-LENS platform delivers an expansive field of vision while maintaining a lightweight feel at just 26 grams. Whether you're rolling through the city before sunrise, climbing into changing mountain weather or riding under harsh Australian midday glare, the JUMBO is designed to adapt with you.

So very versatile. The Alba Optics clip-in can be used in combination with the JUMBO

This version features the VZUM™ F-LENS FLM photochromic lens, developed to automatically respond to changing light conditions. The lens transitions between Category 1 and Category 3 protection depending on UV exposure, helping riders maintain clear vision through:

• early morning bunch rides
• shaded forest roads
• changing weather fronts
• bright coastal glare
• intense Australian summer sunlight

The pink-toned FLM lens enhances visual contrast while maintaining a bright field of view, helping improve reaction time when light conditions shift rapidly. For Australian cyclists who regularly begin rides before sunrise and finish under strong daylight, photochromic technology removes the constant compromise between low-light visibility and high-sun protection.

Three integrated ventilation ports within the VZUM™ J-LENS help reduce condensation and fogging during hard efforts, climbing and variable temperatures. The interchangeable lens system allows future lens upgrades while maintaining the clean aesthetic that has become synonymous with Alba Optics.

The lightweight TR90 frame combines durability with long-ride comfort, while adjustable temple tips allow riders to fine-tune fit and helmet compatibility.

Like much of modern Italian cycling culture, the JUMBO blends performance and emotion equally. It is technical without feeling clinical. Functional without becoming generic.

For Australian riders chasing long road rides, gravel adventures, alpine descents and everyday training, the JUMBO offers one of the most adaptable premium eyewear systems available.

At Chainsmith, we deliberately stock the photochromic FLM version because Australian riding conditions can change dramatically across a single ride. One lens. One pair of glasses. Broad versatility.

JUMBO. Ready to fly.

Scenario

When the road looks infinite and the breath chews dust. Sweat sticks to the clouds and fatigue bites the calves, heart and mind. When the imagination is lost in rectilinear sequences between the sunrises and sunsets of life. When a sky devoid of secrets clings to the handlebar, loneliness is a childlike happiness that caresses the moon and the seasons slide away on the trees, the stones and deserts. Dedicated to you, the cyclist who rides alone on the roads of the world.

SOLO features the highly regarded VZUM™ lens. A central vent in the frame, and slots along the top of the lenses allows heat and steam to escape before it can cloud your vision. The temple tips are telescopic, adjusting to 4 different positions for best fit and wearer comfort.

SOLO has been designed to be worn for prolonged periods of time and multi-day excursions, in a variety of climates. The combination of a durable, flexible and lightweight frame, retromodern styling and modern technologies, the SOLO offers ultimate versatility and purpose.
