My friends Nick Frey, Tom Yersak, Doug Wolf and I built this bike as a project for our engineering design class at Princeton University. The bamboo was sourced locally, torched then baked in an oven to remove the moisture from the poles. They were then mitered to fit snugly to the ajoining tubes and then wrapped in single strands of resin soaked carbon fiber to create the joints. The dropouts were designed in ProEngineer and CNC'd in a 3 axis machine. The head tube and bottom bracket were hand machined from aluminum stock, as was the seatpost adjuster. It rides very very smoothly and is quite strong.
