Diamante SV 45° Anniversario

Our finest Diamante SV, the bike that crystallizes 45 years of experience and perfectionism: 45 years dedicated to perfecting your ride.

A small production, as it was originally, in a limited and numbered series of 45 pieces. A collector’s item, but also a very high-performance bicycle. A bike that does not want to be a point of arrival but a synthesis, the forerunner of Basso’s future.

The rarest and most precious Diamante


The starting point is Diamante SV, a perfect blend of technology and design that makes this the best Basso ever. It’s our quest for the perfect bike: Super Fast, Super Versatile. This time even more unique and refined.


The exclusive 45th Anniversary livery, on which the Sapphire-colored details stand out, is the result of the work of our creative team with our painting experts.
Pure White: the purity of a bike without compromise.
Chrome Blue Sapphire: a jewel that is embellished with the chromatic details that celebrate Sapphire’s wedding.
Glossy Rose Gold: the prestige and charm of pink gold that tells about Vicenza and its deep connection with the goldsmith’s art.

“I wanted to create a bike without compromise, free to be the best expression of what Basso is today, of who I am. Inside there is only the best, until today. The definition of ‘state of the art’ of our first 45 years: the Diamante SV 45° Anniversario.”

Levita Integrated Handlebar

The Diamante tip for unprecedented handling: stiff, light and ergonomic. Levita redefines the concept of riding precision in a heap of technology and aesthetic purity.

Presented for the first time on the 45th Anniversary Diamante SV, Basso’s new integrated system adds a fundamental element to the best riding experience.

Diamante SV 45° Anniversario

Proudly rooted in the territory

What does Vicenza, the territory we come from, teach us? A perpetual search for aesthetic and functional perfection, capable of arousing admiration and inspiring the rest of the world as the architecture of Palladio and the masters of the goldsmith tradition have done for centuries.

45 years is a big part of life

I had the immense luck of being able to dedicate them to my vocation, building something day after day into which I poured all my passion, my dedication, my perseverance. Inside there are me, my family, all the people who have worked with us over the years. Over time, technologies have changed, the approach to cycling, the world that gravitates around it. Yet, even though a lot has changed in recent years, some things remain unchanged. 45 years ago, this adventure started with the same aim that we pursue today: to create the best riding experience.
