Here is my version of gear calc. It's small Open Office's spread sheet. It allows to calculate spead depends of wheel size, engine's RPMs and sprockets sizes in standard engine set and Shift Kit with standard bikes gears on rear wheel.
I hope it will be usefull for somebody
It'll be nice to see some suggestions and ideas to bild up this calculator.

Very cool and thanks for sharing Coval.

I associated this with MSW infopath 2003 and won't work. Any one know how I can get it to open in another program?
