Prima Disco

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.

Our Prima frame is painstakingly finished in our atelier in Milan. First, the frame is adorned with Passoni graphics through an anodisation process, after which we 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.

Our Prima frame can be built to accommodate disc or rim brakes alongside mechanical or electronic groupsets, and our Ready-to-Ride Prima frames are available now. You can choose from six sizes customise the bike to your specification.

Il tubo di sterzo conico da 56 mm della Prima è creato da tre pezzi di titanio di grado 5 saldati insieme. Soluzione che offre il massimo livello di maneggevolezza e un'elevata precisione in termini di tolleranze delle calotte dei cuscinetti. Alloggiando le coppe dei cuscinetti in acciaio inossidabile da 1"½ in basso e da 1"⅛ in alto, il tubo sterzo conico è il fulcro dell'elegante carattere di guida della bicicletta.
