Bicycle with titanium frame.
We wanted to make a bicycle out of all industrial and aesthetic standards. It is a bicycle that is unique in its craftsmanship. Spinas combines Italian conception, construction, technology and design. The frame design is devoted to maximum performance; the frame is rigid, with spectacular propulsion performance; makes you want to pedal from the first meter. All this thanks to the innovative down tube with a trilobate section optimized in terms of stiffness-to-weight ratio (thickness 0.50mm).
