Back in January, I was presented with a large carbon fiber tube, in the form of an oar. Being who I am, I made the obvious decision to build a bicycle frame out of it. As I found out when building my bamboo bike, making a bicycle frame from scratch, especially when using composites, is not actually very hard, as long as you have a lot of patience. To make this project more interesting, more challenging, and cheaper, I built the entire frame and bicycle without spending any money on it. Every component (except the pedals, which used to live on the bamboo bike) I either made myself or scavenged.
