ONDA FP ONDA FP has a special reversed double S carbon fibre fork & chainstays, a shape Pinarello developed from two years of intensive Finite Element Analysis computer research that is the best solution for longitudinal & lateral stiffness and vertical shock damping. ONDA FP was created exclusively for the new DÒGMA FP integrated headset. ONDA FP's reversed double S offers a more stable ride in the turns and under breaking, and good damping from road shock without affecting steering; this offers 5% more overall stiffness and 10% more over our Beta fork.
