Title: Gear Charts/Calculators, etc
Post by: cycloneracer on October 14, 2007, 09:14:00 pm
Here is a gearing chart that I found that has been very helpful.  It is from 9 tooth to 23 tooth. and 9 tooth to 60 tooth.   This is the only one that I have found that goes that small on the rear sprocket.
Hope this helps!  Feel free to post other gear charts in this topic.

1:1 Gearbox Speed and RPM Chart
https://docs.google.com/spreadsheet/ccc?key=0AkskuszqFgg-dGNnQlBRU3IxTDd0SlB5QnZCamdTVHc#gid=0

Here is a Speed/RPM Chart I made for the 1:1 Gearboxes people use.
I have been asked alot of questions about gearing lately, so I figured I would just build a calculator.

This is a shared Google Document;
 ONLY TYPE IN THE YELLOW BOXES
Typing in other boxes will mess up my formulas!

It figures gear ratios and can figure MPH from Engine RPM as well as Engine RPM from MPH.

Here is a link to repaired calculator, someone typed in the red boxes....DO NOT TYPE IN THE RED BOXES
If you would like it to work different, download it to your computer and do whatever you want to it.

If you do accidentally type in the red boxes, please let me know so I can fix it!
