Does monocoque neccesarily mean one complete bike frame? I know that alot of bike manufacturers label their frame as monocoque construction but is really two monoqoque pieces welded together (as far as the aluminum mountain frames go that I am aware of) The seam runs right down the top of the top tube, bottom of the down tube, etc. I'm sure you have seen these frames. The Intense M1 and Tazer FS, Tomac, etc, are good examples

As far as a monocoque carbon frame is concerned, unless there is some sort of lost material in the frame voids, I cannot come up with an answer either.
