Passoni's Prima frame is painstakingly finished in Milan. The frame is adorned with Passoni graphics through an anodisation process, after which it is applied with apply glass bead blasting treatment to the welded joints and tubes.
The Prima uses triple-butted a 42.4mm bi-ovalised downtube, creating a rigid and lightweight platform for riding efforts. That’s complemented by oval titanium chainstays, which preserve the transfer of power horizontally but allow some degree of vertical flex to improve comfort.
The Prima’s 56mm conical headtube is created from three Grade 5 titanium pieces and welded together, offering the greatest level of handling performance, alongside high accuracy in terms of bearing cup tolerances. Housing 1”½ lower and 1”⅛ upper stainless steel bearing cups, the tapered headtube is a centrepiece in the elegant ride character of the bike.
