Damon Rinard does a good job of explaining how he built a room temperature
carbon fiber bicycle frame in his garage. I think this is applicable to
unicycles, especially the curve that allowed him to skip the down tube.
Creating a curved MUni frame might allow the "crown" to be placed ahead of the
problem contact area at the top of the wheel. I am very interested in creating
such a frame, after I finish my taxes and get some firewood stashed. It will
take awhile to get the appropriate materials.
