An update about my frame:
The frame rides great so far, but I have had some issues. First of all, my dad took it on a test ride without asking me, and heard a crack while riding up a steep hill. Neither the bamboo or carbon joints broke- what happened was that the bond between the bottom bracket lug and the downtube failed, so the tube could slide in and out of the lug. Apparently the epoxy did not bond properly to the bamboo. I fixed this by drilling a hole through the lug and bamboo, glueing a hardwood dowel into the hole, and wrapping the joint in carbon fiber another 2.5" up the tube. I made sure to rough up the surface much better than before using my dremel. Before, the bamboo was just sanded. So far it works great, and I have really mashed it without problems.

Second problem just happened this afternoon, conveniently right before I was leaving for Critical Mass. I jerked my shifter harder than I should have, to switch from the highest to lowest gear, and popped the cable stop off the top of the downtube. I temporarily fixed it with some gorilla tape, but I will wrap the stop in carbon later.
