In this episode of Service Course, Tom Whalley and Lizzy Banks continue in their pursuit to track down the makers of the world's first 3D printed carbon bike. They talk to Henry Furniss who co-founded WyndyMilla but has now moved on to create his own R&D business for 3D printed technologies. They discuss Henry's current project creating 3D printed lugs, that feeling when you wake up having realised you accidentally pressed print on a carbon superbike, and whether the crowd-funded Superstrata really is the world's first rideable 3D printed carbon bike. They also speak to Marcel Fowler from New Motion Labs about how they have reinvented the chain, creating a completely new chain design that reduces friction and distributes the load more evenly over the chainring and sprockets. Is this a technology that will mean we will see plastic chainrings and sprockets in the future?
