Color: Candy Red GLOSSY


It has been 22 years since the first Diamante was released. 22 years in which Diamante has gone through 8 evolutions to become what it is today: the most Basso bike of all.
Our most long-running bike, stainless like any self-respecting diamond. A process of constant and meticulous improvement, often working on invisible details, capable of combining innovation aimed at the future and the legacy of over 45 years of Basso.


Leaving the starting point to go elsewhere, outside your own schemes, to explore and then come back enriched, so as to evolve what you started from. A circular movement that becomes a spiral as it perfects itself, enclosing the past and the future. The spirit of Basso flows in the circular tubes of the Diamante frame. A shape that is not just an aesthetic solution but the research to obtain the best performance from a material, carbon.



How do you redefine a classic? By obsessively working on details, considering each arrival point as a new starting point. Diamante introduces improvements in the geometry that make it more performing uphill and downhill. Every good bike fit starts with choosing the correct frame size for you. This will allow you to benefit best of the bike’s performance and comfort for an efficient riding position.
