This “Geometry Measurement Tool” allowed Gary Fisher to sample different geometries in actual riding conditions. Making minute changes in bottom bracket height and fork rake, Fisher was able to fine tune and test, noting the changes and making immediate comparisons to the previous settings. I was told that it was put together by A. Eisentraut, a San Francisco Bay Area frame builder.
This is not a bike!
