The latest evolution in cycling specific to PIAGGIO Zip. Reinforced lock frame, with elongated pitch. Deliberately raw welds, anchoring to the split engine block (maximum freedom in terms of mingled conformation), which can also be used with the original engine part. Laser-cut tube-cut arms (unlike traditional frames that employ structurally weak arms, made from bending). This set ensures never-before-seen rigidity and stability, soon available to all zip PIAGGIO owners! Made in Italy 100%
