2025 IMPERO SPECIAL EDITION
TRIBUTE TO MILAN

TRIBUTO A MILANO
"A city is made of memories, and a bicycle is how we ride through them."
ACOL’s first Limited Edition is more than just a collection. It’s a tribute — to the symbols, the stories, and the roots of Alex Colnago in the city of Milan. This Limited Edition favors meaning over mere aesthetics. The Biscione, the Duomo, the red cross on white, the colors of its two football clubs...Each element is a scene from Alex’s youth — graphic echoes of the spirit of Milan.
“Impero is not just a bicycle. It’s the way I ride through the city that shaped me.”
– Alex Colnago

The Art of the Finish
This making film showcases the entire painting process completed in our own factory. From precise masking to delicate decal application, every step reflects our commitment to craftsmanship. Not only do we lead in advanced materials like nano carbon, but our expertise also shines in final processes such as painting and finishing.

Milan is remembered in colors.
The red trams weaving through stone-grey buildings, the roar of blue stadiums, the golden hue of sunset on cathedral spires.
ACOL’s first limited edition captures these very colors on the surface of a bicycle frame.
The deep green of the Biscione, the marble white of the Duomo,
the blue and red of the city’s rival teams, and the red cross on the city’s flag — together, they speak the visual language of Milan.
This is not just graphic design.
It is a layered expression of a city, told through color.
Milan l'é un gran Milan
This Milanese dialect phrase has long embodied the spirit of a proud city. A city that lives between fashion and industry, art and sport — never confined, always evolving.
ACOL’s limited edition bicycle reflects that same energy.
It doesn’t chase spectacle; it honors detail.
It doesn’t shout luxury; it whispers affection.
A small inscription, a hidden coordinate — each holds more than it seems. This bicycle is a quiet tribute to a city that is, truly, great.


Symbols speak for a city without words. And Milan has many.
The Biscione, an ancient emblem of identity and power.
The Duomo, a vertical testament to history and devotion.
The red cross, a symbol of heritage.
The team colors — a constant rivalry, forever coexisting.
Each element has been distilled and placed with care onto the frame of this bicycle.
They are not decorations;
they are the memory of a city, made tangible.
Only 25 will be made. No more.
Because the value of a limited edition is not in the number — but in the weight of what it represents.

Up to 35mm Tire Clearance
Generous clearance accommodates everything from race slicks to wide tires for cobblestone sectors, ensuring both stability and comfort across diverse terrain.
Fully Internal Cable Routing, Broad Compatibility
All cables are housed inside the frame, reducing drag and creating a clean, refined appearance.
It’s a design that balances aerodynamic function with visual clarity.
Perfectly compatible with the DIVINUS and TUSCIA frames, and also connects seamlessly with third-party systems using FSA-standard spacers.
The design maximizes both system integration and setup flexibility.

Wide Flare Angle Compliant with UCI Regulations
An 11° flare creates a 30mm difference between the lever width and drop width, enabling stable and powerful power transfer during intense sprints.
This regulation-conscious design delivers both performance and compliance.
Redefining the Essence of Performance
Through precise structural optimization, we’ve reduced weight while maintaining stiffness and responsiveness.
The silhouette, based on NACA aero profiles, minimizes air resistance, while a wide range of fit options and customization choices allow precise tailoring to each rider’s needs.
Compatible with both mechanical and electronic drivetrains and fully compliant with the latest UCI regulations, the Impero delivers complete performance in real racing environments.

The Ideal Balance of Stiffness and Lightness
Capable of supporting high rider weights without compromising performance, the Impero seatpost is engineered to accommodate a wide variety of fit demands.
