Bike Specific Computational Tools
These spreadsheets tools in Excel format were developed by Sanders, Snyder & Tetz. They represent many days of work by the authors, and will give the intrepid builder or researcher the ability to quantify bicycle related issues such as determining your own power capabilities, power vs speed, power to climb hills, CdA (aerodynamic drag), Crr (rolling resistance), and many more.

Also included are instructional texts to help guide the user in making proper measurements.
