INEOS Grenadiers riders to compete on flagship time
trial bike while representing their respective nations
Pinarello has unveiled the latest incarnation of its iconic Bolide F TT which it hopes will propel INEOS Grenadiers riders to victory at the Paris 2024 Olympic Games while representing their respective nations in the Individual Time Trial.
Michał Kwiatkowski (Poland), Magnus Sheffield (USA), reigning European Time Trial Champion Josh Tarling (Great Britain) and former World Time Trial Champions Tobias Foss (Norway) and Filippo Ganna (Italy) have each received a carbon fiber version of this revolutionary bike in a unique colorway which blends Luxter Red Gold and Luxter Blue and features their nationalities on the seat tube.
The Bolide F TT utilizes many of the same technologies that have been applied to the updated Bolide F HR models being used in endurance events by the Italian track team.
Ground-breaking
This fully updated design has achieved a 2.28% CdA reduction compared to the previous Bolide F TT by incorporating the following key features:
AirStream technology – Developed in collaboration with the University of Adelaide and aerodynamics R&D partner NablaFlow, and inspired by the tubercules found on the flippers of humpback whales, a unique pattern of AeroNodes has been integrated onto the seat tube and seat post to reduce the complex vortexes generated by riders’ leg movements in order to improve airflow.
AirFoil sections on the bottom bracket and wheel hubs are longer and slimmer to reduce the frontal area. These innovations take advantage of the UCI’s decision to remove its 3:1 rule and research found aspect ratios of 6:1, and even 8:1, performed significantly better than the original 3:1 benchmark.
Reinforced chain stay and bottom bracket – This has allowed tire clearance to increase from 28mm to 32mm, compared to the previous model, without compromising responsiveness and stiffness.
Narrow forks and seat stays – Recent trends in aero frame design have seen a shift towards wide forks and seat stays to try and reduce the overall drag of the bike and rider. Our extensive research in this area – which included over 2,000 Computational Fluid Dynamics (CFD) tests – found however, that the narrowest possible forks and seat stays minimized the weight of the frame and yielded the fastest overall results in multiple wind speed and yaw angle situations.
Fork flap chip support – The new Bolide F TT fork features the same fork flap chip support found on the new DOGMA F for additional aerodynamic gains.
Optimized handlebar geometry was achieved as a result of intensive CFD testing to minimize the total drag of the rider and bike. Again, we collaborated with NablaFlow to conduct countless simulations using their AeroCloud software – which runs on AWS, the preferred cloud solution of the FIA and many F1 teams – to determine the most efficient design.
Improved bottle cage integration – Our CFD studies also took into account optimal aero bottle cage and bottle positioning, achieving a simpler, more reliable, and more aerodynamic solution.
Tried and tested
The Bolide F TT shares the same geometries and dimensions of the current Bolide F TT and is available in four standard frame sizes which have been checked and approved by the UCI.
Pinarello President Fausto Pinarello said: “There is no greater stage than the Olympics to launch a new bike and we are immensely proud of the new Bolide F TT. It is a bike that continues to push the boundaries of athletic performance and will ensure our riders have the very best chance of success in Paris.”
