First frame build!
Hello all, some of you may be familiar with me but I've been posting sporadically building a bamboo bike over a long period of time. Well I finally got around to it and here is what I've got so far! I'll update the thread with some more pictures including the build process. The seat tube that I had was 1" which isn't very common so I'm going to get a larger tube then mount it in the frame. That should happen real soon! Let me know what you think!
Can you tell me the length of the head tube you used and the size of your bike? I'm building about a 53cm road bike from bamboo and figure on using a 130mm head tube. Want to know if this sounds about right.
Oh yeah, bike looks great!

For your headtube and bottom bracket did you use raw material or did you cut apart an old frame and use an existing headtube and bb shell with the old tubing attached? Also for the drop outs what did you use to fill the gap inside the bamboo?

That is amazing. How close are you to being able to ride it?

I used a 110mm Headtube, I could have used the extra space that the 130mm would have provided but obviously I made due with less.

I ordered the head tube, drop outs, and bottom bracket shell from nova cycle supplies. I used a combination of epoxy and bamboo saw dust for filler. I then smoothed out the edges of the bamboo on the outside a bit so I could more easily lay carbon over to provide a little bit more support. In the future I would like to do some more testing to find the best, strongest and lightest, way to improve that joint.

Thanks a lot! I have ridden it around plenty with out the seat. I will get that on hopefully within the next week as I now have my finals completed!
