I have a Merida bike with "Shotgun technology" frame. The cross bar, and the diagonal bar down to
the pedals (downtube?) have been built around an alloy "double barrel shotgun" type of tubing for
extra strengthening. In other words two tubes side-by-side are in the middle of the cross bar,
and downtube.

What intriques me about this, is the triangle of tubes comprising the tube from the seat post down
to the pedals, and the tubes from the pedals back to the actual wheel, and from the wheel back up to
near the seat, are all very thin normal tubes without this "double barrel shotgun" reinforcing
within the tubes.
Yet my totally ignorant impression would be that in almost any stressed situation such as a landing
from even a small jump, would put the forces on this rear "triangle" rather than on the crossbar,
and downtube.
It seems to me that the wrong tubes are reinforced
What parts of a frame fail most often, and where should they be reinforced.
