Table of the gear ratio

These are just a common ratio as a reference.
It would be great if this helps you to find your suitable ratio.

Some colored cells indicate common ratios people are running.

Green: for modified bikes (20")
commonly running at 1.30-1.50
Purple: for stock bikes (26")
commonly running at 1.10-1.30

These values are rounded off numbers to the nearest three places of decimals.
