3D-printed Pinarello Bolide F HR 3D alloy track bike of Filippo Ganna's Hour Record attempt
Filippo Ganna is set to attempt the Hour Record this week on a “World’s First” fully-3D-printed Pinarello Bolide F HR 3D track bike.
3D-printing did give Pinarello designers an unprecedented level of design control and customization potential relative to either modern carbon bike manufacturing or more conventional metal bike building. They could create a seamless aerodynamic exterior skin, while at the same time incorporating infinitely customizable internal structural reinforcements to boost stiffness exactly where the bike needed it.
Aluminium-Magnesium alloy called Scalmalloy that was developed in the aerospace industry, specifically for additive manufacturing. Created on a large-format printer, the bike frame still had to be printed in 5 individual parts, that were then bonded together with epxoy after some post-printing clean-up.
To make sure Filippo Ganna’s custom bike was strong enough & safe enough, Pinarello made an exact duplicate of it to be independently tested by EFBE in Germany. The Bolide F 3D frame, fork & seatpost passed the full range of fatigue, impact, and torsion tests as specified by ISO4210 – a first for a custom UCI Hour Record attempt bike.One of the standout features of the Bolide F HR 3D is its AirStream tech ribbed seattube tubercles… or AeroNodes.
