Would be very difficult to make though.

an old headtube and crown, insert bamboo into those. then miter the ends and put in dropouts.. would look great

Those who know more than me feel free to correct me (I haven't taken strengths of materials yet, next term

) but I believe that if you use bamboo in the fork you're changing from just an axial force (tension/compression) to axial, shear, and torquing forces. I highly doubt you'd be able to make a bamboo fork last a reasonable amount of time, especially with a front brake mounted on it.

Also, the other day I saw a bamboo single speed in a bike rack. Took a look at it but couldn't get a picture (got a super cheap phone haha) It was built with bamboo and fiber wraps. The chainstays were the same size as what you've been saying so I think you're good there. The thing that caught my eye was the headtube though, it was covered in nearly an inch think wrap. The fibers in use for this bike were larger than yours though, so I don't know how that factors in. Considering that OSU is a huge engineering school, I'm certain that this was a senior design project for a mechanical engineer. So you're not alone in trying this, and it's definitely possible. Good luck man.

Awesome...takes alot of worrying out of the rear triangle for me
