The eXtreme rib is entirely constructed out of prepreg carbon
using state of the art Formula 1 autoclave technology.

Formula 1 technology

The eXtreme rib is an innovation in rib construction. The hull is
manufactured from 4 millimetre solid carbon fibre, in strength
the equivalent of 6 millimetres of steel, but at only a fraction of
the weight. The hull and other components of the eXtreme rib
are constructed out of prepreg carbon using autoclave
technology for the best carbon-epoxy ratio: very light, yet
extremely strong. This technology originated from Formula 1
cars and can be used to produce any shape desired.
