The Geometry

Basso developed geometry studied to confer the perfect blend of snappy handling and acceleration and a comfortable position for the long haul.

“At Basso, it’s all about creating the best riding experience for passionate cyclists like you and us.”

Carbon construction

The carbon layup was studied to ensure an extremely reliable structure that is both vertically compliant yet laterally efficient and reactive.

Fixed pivot

Shape and layup were developed to ensure a more compliant, more forgiving ride while maintaining horizontal stiffness for responsive handling.
