During stage 13 of the Tour de France, the individual time trial on 15 July, Tom Dumoulin will be racing his brand-new skinsuit, jointly developed by Team Giant-Alpecin and the TU Delft. The university applied an innovative method to research the aerodynamics of the suit: Dumoulin’s body was first scanned, after which a 3D mannequin of his body was printed. The drag of this mannequin – each time with a different suit – was then tested and optimised in the TU Delft’s wind tunnel.
