T-Bar Specifications


The data below was gathered by setting up a test jig and measuring the amount of force needed to flex the T-Bar. Side to side or Torsional measurements were made by lifting one rear tire to heights of .100, .200 & .300 inches and recording the grams of force required. Front to back or Longitudinal values were recorded by lifting both rear wheels off the surface to heights of .100 & .200 inches.

The following information was provided by Danny King & TRC.
