The form of the new ONDA 2 improves aerodynamics significantly, eliminating the empty space between fork and down tube, effectively creating fork and frame that act as one body. By eliminating the space between fork and frame drag is significantly reduced as there is no longer turbulent air between the two. Equally important is the new form’s impressive effect on stiffness of the front end. The new form is 19% more rigid when analyzing only the form and geometry and becomes even more rigid when taking into account that it is constructed with our new Torayca 65HM1K carbon with Nanoalloy technology. ONDA 2 is strong, resistant and reactive with a special profile to ensure even more rigidity. The right leg is a bit larger with a different structure than that of the left one in an effort to compensate for the asymmetry of forces applied to the bike both during normal use as well as under more extreme circumstances such as sprints or climbs with high gradients.
The PINARELLOLAB has introduced the E.P.S. (Expandable Polystyrene System) production process in an effort to both increase rigidity and safeness as well as to decrease the overall weight of the frame. Increased compaction makes for a more rigid frame which allows you, the rider, to have greater control of the bike and lose less energy due to frame flex laterally.
The E.P.S. process allows Pinarello to eliminate extra and unnecessary material as the compaction of carbon layers is optimized thus translating into an overall weight savings. This process also eliminates small imperfections that come about under traditional frame production methods. These imperfections are often the cause of structural failure and represent a risk for the rider. By eliminating these structural imperfections through EPS processes, Pinarello has improved the safety of its frames above the industry standard.
The E.P.S. system consists in laminating carbon sheets around Polystyrene forms with perfectly smooth surfaces and leaving these forms inside the mold during the pressure phase of production. The mold expands both due to increased heat in addition to added air pressure leaving a controlled and optimized thickness of carbon material throughout the frame. The polystyrene mold is then removed when the production process is complete.
When subjected to violent impact, carbon fibre can snap, with evident safety hazards: dangerous flying splinters that can injure the cyclist and the possibility of a crash.
Toray has solved this problem by inventing a system that prevents microfractures from spreading and avoids immediate collapse with the neat rupture of the fibres.
The extraordinary Torayca Nanoalloy™ technology consists of nanoparticles embedded in the carbon fibre mesh that explode on impact to prevent the fibre from breaking.
Our current 50HM1K fibre is already 29% stronger on impact than conventional fibres. The new 65HM1K with Nanoalloy™ technology adds another 23% to that advantage, making it 59% more resistant than conventional fibres.
Toray® has been our exclusive supplier for the last 5 years. The Japan-based industrial colossus supplies the most important aerospace and automobile industries and is a world leader in terms of production output, technology and innovation in the field of special fibers. The Torayca® division, dedicated to carbon fiber processing, will supply the newly developed 65HM1K fiber with Nanoalloy™ technology.
Carbon fiber starts as a filament measuring 5-8 micrometers in width that is produced through a long and complicated process of pirolisi oxidation and carbonization of Polyacrylonitrile and is the material with the highest resistance to breakage weight that exists in the market today.
When we refer 65HM we are referring to fiber with a tensile modulus of 65 tons per square centimeter. When we refer to 1K it means that there are 1000 fibers per strand
Using a highly resistant and reliable fiber such as Torayca 65HM1K with Nanoalloy™ allows us to employ less material compared to traditional fibers, hence the final weight is lower, although stability and safety are improved.
This term indicates the construction methodology used when constructing our frames.
SOE is the acronym for SIMULATION OPTIMIZATION EVOLUTION whereby the initial tests in the design phase are done via technical software which simulatesresistance, fatigue, stress, aerodynamic impact.
This ensures the realization of a prototype in an advanced stage and eventually leadingto a final high-performance frame.
