BITD I had the '93 brother to this, the Explosif, which had both the frame and fork in Tange Prestige Concept, I also had the Kona brochure (sadly parted with it when sold the F&F) and it quoted the Explosif, as having the identical tubes as the Hot, only welded in Taiwan, i.e Prestige Concept. Also interestingly in the blurb on the Hot, it advertised custom sizing AND paint, so this hopefully answers some of the questions.
