|Guzzi Gearing Spreadsheet by Mike Wright
For those interested, here's an MS Excel file <click to download>. It contains gearing specs and theoretical speeds per gear for the bikes listed in the gearing section of Guzziology. For those who want to play with different gearing for their bike(s) all you'll have to do is cut & paste from one model to another. I didn't know all the different tire sizes used and I had to guesstimate in some cases, so if I'm in error or missing data let me know and I'll update the file.
