This bespoke road chassis represents the height of French artisanal constructeurs. Built in the workshops of Jacques Busset, this specimen uses the legendary Vitus 980 double-butted steel tube set, yielding a performance-focused stiffness-to-weight ratio designed to rival premium racing alloys of its era. The frame features exceptionally clean, lugless fillet-brazed joints (soudo-brasé) which minimize excess material, giving the joints a sleek aesthetic profile while maintaining maximum structural efficiency.
