Basso Diamante Disc 2025 | Shimano Dura Ace Di2 12s | Complete Bicycle

In the circular tubes of the Diamante frame flows the spirit of Basso. A shape that is not just an aesthetic choice but the result of research aimed at achieving the best performance from carbon fiber.

Devotion to Climbing

Today, Diamante reaffirms its passion for climbs and descents. Through meticulous engineering, the weight has been further reduced by over 200 grams, allowing the complete bike to remain well below the UCI weight limit (6.8 kg). A bicycle without a single unnecessary gram, designed to make every pedal stroke an exciting experience and an opportunity to push your limits.

A Timeless Classic with a Contemporary Soul

A unique design, the result of an extremely complex engineering process, refined over the years down to the finest details. A timeless aesthetic that embodies modernity. The perfect balance between lightness and stability, maximizing the potential of hand-crafted carbon fiber. The tube thickness has been meticulously studied to ensure agility and responsiveness when climbing, as well as stability on descents, even at high speeds.

Ride, Perfected

Stable, responsive, lightweight, and easy to handle. Diamante is a versatile road racing bike designed to excel on the most demanding climbs and descents. A geometry refined over decades through countless kilometers and expert craftsmanship in carbon fiber, achieving peak performance through cutting-edge technology. The result is an intense and engaging riding experience, ready to thrill.

Basso’s Golden Rule of Engineering

We meticulously study carbon fiber to enhance its properties through shape. In areas where energy is generated and dissipated—such as the bottom bracket and head tube—the circular shape reduces tube thickness and weight while increasing torsional rigidity. This ensures that every watt of pedaling power is efficiently transferred into forward motion and precise handling. The result? More lightness, stiffness, and control, preventing power loss and increasing stability.

Geometry

How do you redefine a classic? By obsessing over details, treating every finish line as a new starting point. Diamante introduces optimized geometry for climbing and descending, featuring a shortened rear triangle and a longer front center for greater responsiveness at low speeds and stability at high speeds. A proper bike fit starts with the right size selection, ensuring the most efficient ride, maximum performance, and ultimate comfort.
