Free Spoke Length Calculation Program Executable and Source Code

The following 16-bit DOS/Windows executable binary was compiled and released via the Internet and CD-ROM back in 1996. It was written in C++ and assumes that you are using the same guage spokes that the hub holes were drilled for. In most cases, that would be 2.0mm / 14g spokes in hub holes drilled the same.

For most front wheels, you only need to do one calculation. For most multi-speed rear and disc front wheels, you will need to perform a separate calculation for each side of the wheel you are going to build.

SPOKE.EXE


The following is the source code for the above "SPOKE.EXE" executable binary. Feel free to modify however you like - expand, loop, featurize to your heart's content. Also feel free to port to Linux, OSX, Solaris, SunOS, or just about any *NIX. I've done it for Linux without any issues. If you are familiar with the GNU compiler, and know how to adjust for the paths and calls to the correct and needed C++ libraries - then porting to another platform for you should be a piece of cake!

SPOKE.CPP


Important Note:

The above have been released free to the public. Should you choose to distribute yourself AS-IS or with your own modifications - you agree to do so freely as well with no charge to public or private parties.



Multi-Tabbed Spoke Length Calculation Spreadsheet for Folks in a Hurry

Linked below is a spreadsheet that contains 5 tabbed worksheets that provide the following:

This is an update of Version 1.0 which was released also in 1996.

Simply download the spreadsheet and save to your hard drive. In order to actually use the inputs and calculation of the "Spokechart" tab you will need the following:

Be sure to read all sections of the "Instructions" tab. It explains the function or purpose of each of the other tabs - including assumptions about guages, ERDs, and the like.

Important Note:

Please DO NOT MODIFY the spreadsheet yourself AND THEN DISTRIBUTE TO OTHERS!!! I prefer to maintain editing ownership of the spreadsheet in order to keep it clean, organized, accurate and consistent.

DO CHECK BACK EVERY WEEK OR SO as I do frequent updates as I encounter new hubs and rims and manufacturer publications of hub and rim specs.
