Overview

About this bike

This is an Ex-demo frame and therefore shows signs of use, please see pictures for details.

Built on the success of the award-winning and universally acclaimed Diamante, comes the Diamante SV : not only stiffer but more SV - Super Veloce - Super Versatile.

The Diamante SV uses a seamless fusion of refined craftsmanship and innovative tube shapes to create a timeless aero-orientated UCI Approved road racing bike. Aerodynamically profiled tubes and enhanced stiffness elevate the esteemed Diamante to an even higher standard. Enhancing the already exceptional Basso wasn't just about performance improvements; it also aimed to broaden versatility. This was achieved through a redesigned fork, an exceptionally efficient rear triangle, and expanded tyre clearance. Each aspect of the Diamante SV, from its carbon layup to tube dimensions and construction, has been meticulously adjusted across each frame size to ensure that regardless of your bike's size, you'll enjoy a perfected riding experience.
