In this episode of Service Course, Lizzy Banks and Tom Whalley look at the increasingly important role that 3D printing is playing in bike design. They discuss the 3D printed bars that Filippo Ganna used to win 3 stages at the Giro and the World TT Championships. We also hear from Dimitris Katsanis who designs and builds the 3D printed bars for the Ineos Grenadiers. Finally, we meet James Cook, whose company Hexr have created a revolutionary 3D printed helmet. Tom also does his best to find out which team Lizzy will be riding for in 2021.
