Which was the first of the "modern" Spirit buggies? Shaka?
I was always vaguely mystified by SDC's Rage, which while seemingly on the same pneumatic tires as Spirit & Fringe, reliably managed to have measurably faster rollouts. It seems to have served SDC quite well during the years when their latest designs left something to be desired. It's ancestor was, what, Escargot?
Fringe's Bachi, which was their first one that could do justice to their push teams of the 2000's, and started off their buggy-building frenzy.
