The Astra model pushes the limits farther than any version before it and does so with a good dose of style. Produced entirely in house by the skilled hands of the Basso staff, the latest version of the Astra model incorporates a great deal of technology that derives from its upper tier siblings and adopts a design that follows a tighter family feeling than ever before.
The Astra front end was studied together with the stem and carbon spacers to allow a flush and stiff connection between the parts.
This system improves both performance and aesthetics of the front end.
A totally hidden fixing solution that is invisible on the frame, intertwining technological and aesthetic innovation.
The result is a lightweight, invisible and strong integrated system with three screws, which has been further implemented through the vulcanization of the steel plank. This Basso solution gives the 3B system an anti-vibration function, which improves the riding experience by elevating comfort on uneven and bumpy surfaces.
