Pinarello has actually revealed 2 brand-new versions of its Hour Record-winning Bolide F HR which it hopes will move the males’s and ladies’s Italian track biking groups to triumph in the group pursuit at the Paris 2024 Olympic Games.
The guys’s French track endurance team, who are the ruling Olympic champs, have actually gotten 3D-printed scalmalloy variations of the track bike– the Bolide F HR 3D– while the females’s endurance professional athletes will contend on a custom-made carbon design– the Bolide HR C.
The Bolide F HR 3D was at first established for Filippo Ganna’s effective Hour Record effort on October 8, 2022 where he set a brand-new, still unparalleled criteria of 56.792 km in Grenchen, Switzerland.
The following week Ganna likewise set a brand-new 4km specific pursuit world record at sea level on the bike at the UCI Track World Championships, breaking the four-minute barrier with his time of 3 minutes 59.636 secconds.
Fellow INEOS Grenadiers professional athlete, and the group’s Performance Engineer, Dan Bigham likewise rode a model of the bike when he set the previous-best Hour Record 2 months prior to Ganna.
Pinarello declares that the Bolide F HR 3D was the very first and fastest high-performance 3D-printed bike ever produced, and these newest versions maintain its essential functions, consisting of:
- AirStream innovation– Developed in partnership with the University of Adelaide and aerodynamics R&D partner NablaFlow, and motivated by the tubercules discovered on the flippers of humpback whales, a special pattern of AeroNodes have actually been incorporated onto the seat tube and seat post to decrease the intricate vortexes created by riders’ leg motions in order to enhance air flow.
- AirFoil areas on the bottom bracket and wheel centers are longer and slimmer to lower the frontal location. These developments benefit from the UCI’s choice to eliminate its 3:1 guideline. Research study has actually discovered element ratios of 6:1, and even 8:1, carried out considerably much better than that initial 3:1 criteria.
- Narrow forks and seat stays– Recent patterns in aero frame style have actually seen a shift towards large forks and seat remains to attempt and minimize the total drag of bike and rider. Pinarello’s research study in this location, nevertheless, was not definitive. The business decided for that reason, to embrace a more dependable mix of narrow forks and seat remains to reduce the weight of the frame in order to yield faster outcomes.
- Optimised handlebar geometry was accomplished as an outcome of several rounds of Computational Fluid Dynamics (CFD) screening to reduce the overall drag of rider and bike. Once again, Pinarello worked together with NablaFlow to carry out simulations utilizing its AeroCloud software application– which operates on AWS, the favored cloud option of the FIA and lots of F1 groups– to figure out the most effective style.
Utilizing 3D printing innovation, each frame of the Bolide F HR 3D integrates simply 5 parts; with the front triangle making up 3 pieces in addition to seat and chain stays.
Scalmalloy was picked for the guys’s design as its homes permit it to carry out under the increased forces and speed that male professional athletes produce,
