Creating the rear triangle, consisting of a rear stay and a chain stay, is the next step. Thinner bamboo pieces will be used for the chain stays and thicker pieces are used for seat stays. Builders shape the seat stays and chain stays using stainless steel dropouts. The rear stays are shaped using a saw and some final shaping with a knife.
The seat stays are then aligned and prepared for tacking. For added strength, metal inserts are placed after everything is positioned correctly. Electrical tape will be used to hold everything in place while it dries and then it is time for the next phase of the process.
