"This team issued Slingshot was 1 of 18 made for the 1992 race season. Slingshot bikes use a unique mid-frame suspension system. The conventional down tube is replaced with a steel cable suspended from a spring. There is a hinge on the top tube right in front of the seat tube. The idea is to use the spring and cable system to return the energy lost during the pedal stroke. All of the energy is returned since there are no frictional or damping losses in the spring system. This was the first Slingshot to locat the spring behind the head tube, this was done to eliminated some noise and fatigue issues. Prior to this, the spring was mounted to the bottom bracket."
