Being a Ti frame, did they actually change from year to year.
I know the steel frames did, but with Ti I would have thought there was less choice of things like dropouts, tubing etc... to improve them.
and iirc (from you) Kona didn't really alter their frame geometry.
Well you may like to note that they upgraded the Explosif dropouts between 1996 and 1997, as the previous type were prone to snap! But I don't know of any difference whatever between say the 1998 and 1999 Explosifs.
Similarly, there was quite a lot of change to the ti designs leading up to 1997, but I think they kept them the same from then on. The Hei Hei had geometry slightly different to the other Konas from 1994 to 96, in terms of the flatter top tube. That may have been to make the frame stiffer, as heavier riders had complained of excessive flex. That was quite a common complaint about ti bikes at around that time, perhaps because it is possible with ti to build a really light frame that is still strong enough for mtb, in the sense that it won't break, but not stiff enough for the most demanding riding styles. i.e., despite the myths, light doesn't necessarily equal fast. And I guess as suspension forks lead riders to ride in a more aggressive style than in earlier times, the case for a light and more flexy frame became weaker. I believe that Litespeed in particular went to great lengths around then to stiffen up their frames with sophisticated tube shapes.
Kona's response was the King Kahuna which came out in 1996 as the stiffer, racier option, initially just with fairly minimal gussets. For 1997, they went over to the standard Kona geometry for the ti bikes, with the King Kahuna having fatter, shaped tubes that make it a fair bit stiffer and a quarter of a pound heavier than the Hei Hei. Interestingly, despite being 25% more expensive, the KK seems to have taken over in the sales and by 2000, the last year of the ti frames, they had dropped the Hei Hei in all markets as far as I can make out, and offered only the King Kahuna.
