Second structural layup to the bicycle frame. This one is over the down tube.
Bike frame core segments prepared for first carbon composite layup

Down tube wrapped with elastic compression banding

Protective caps were 3D printed and assembled into the head tube and the bottom bracket. Pivot tube protectors were also reprinted at a higher resolution to improve the surface finish to make removal (after all structure composite applied) easier.
