3D printed bike saddles are practically mainstream now, so it was only a matter of time before 3D printed padding came for cycling shorts. The new Aura N3X FL from Elastic Interface is a digitally engineered, 3D printed, open-geometry padding insert to improve ventilation, pressure distribution, and long-ride support. Designed as a component for cycling-apparel brands — rather than a finished pair of shorts — these could soon be turning up inside your favorite cycling shorts, giving 3D printing another intimate assignment.
