Wind Tunnel Test Data: Aerodynamic Comparison of Disk Wheels

Stored away for future use because I know it will come in handy at some point in time...

Below is a chart of aerodynamic drag forces on disk wheels.

This data is the result of testing performed at the University of California - Irvine Wind Tunnel in January, 1991 and reported in the March issue of Cycling Science that year and on a now-defunct web page at the University of Maryland.
