Hey! How do they get the solid form out of the frame?!! :-)
They just lift it out. If you look closely at the video, you'll see the half-form several times. You make a left half, a right half and join them together. "Monocoque" doesn't mean "made in one piece," although many people think it does.
could anybody venture a guess as to what percentage of the cost of a scott paid for this high-end production value marketing material?
I can't, but you have to keep in mind that marketing costs in general are a large percentage of the expenditures of a company selling carbon bicycles. The only companies where that percentage may be a bit less are those who actually manufacture some or all carbon frames in-house. But even with those, marketing is what determines survival or failure. Point being: a video here or there is a drop in the bucket.
