Mike Augspurger: "If I remember right, my customer was Slingshot. I don't remember why they wanted a ti version. I do remember that I wanted maximum frame stiffness and couldn't get a fat enough tube for the top tube. So My friend Mike Ballou (the glue guy) and I filled the top tube with fiberglass honeycomb inside a carbon fiber sock. That explains the lugs. They supplied the cable, spring, and the fiberglass hinge (a piece of Corvette leaf spring). John Kukoda from Bicycling magazing called it, "The lightest version of the fastest mountain bike we've ridden". Before rear suspension, there was a small window of time there where Slingshots were impressive, wobbly handling but quite compliant.""
Scott Quiring: "While I am not 100% sure, I believe there was only one ti slingshot like that made by Mike Ausburger in around 1990 or 1991. The last place I saw that frame was at Wild Rose in Salt Lake City Utah in 1992 and the shop owner was riding it (not sure of his name though). Then starting in about '93, Mark Groendal, the inventor of the Slingshot, I believe had Titus in Arizona make several titanium slingshot road bikes and mountain bikes (The production of steel framed Slingshots still remained manufactured by Greendale Bicyle Co., in Grand Rapids Michigan, however) The Titus built Slingshots had a distinctively larger diameter boom tube when compared to the Ausburger frame, if I recall correctly. A few rear ends where made by Titus but ultimately I can't remember if they became popular or not. Marten Stenger, a top NORBA pro at that time, successfully raced a Slingshot that had a Titanium boom tube mated to a True Temper 4130 steel rear end on that national racing circuit.
